- the UI logic 64 configures the screen display of computer 26 a with an application-specific user interface tailored for the control of and interface with the particular EP system selected by the user.
- the “EnSite” system is selected, so the UI logic 64 alters the visual appearance of the “EnSite” button so that it is visually distinguishable from the other, non-selected buttons in group 70 .
- the “EnSite” button may appear depressed or otherwise shaded differently than the other, non-selected buttons in group 70 . This always lets the user know what system is selected.
- the UI logic 64 in an embodiment, also maintains the application-selection buttons in group 70 at the top of the screen regardless of the particular application selected by the user. This arrangement allows the user to move from system (application) to system (application) quickly and control each one independently.
- UI logic 64 presents an application-specific user interface tailored and optimized for control of and interaction with system 34 .
- This user interface includes a second, common-task group of selectable buttons, designated group 72 , a third, view-mode group of selectable buttons, designated group 74 , a fourth, view-select group of selectable buttons, designated group 76 , a flattened joystick 78 configured to receive view-manipulation input from the user, a voice recognition control button 80 , and a settings button 82 .
- Each group will be addressed in turn.
- the second group 72 of buttons includes a listing of common tasks performed by an EP physician when interacting with system 34 .
- Each of the buttons in group 72 are associated with a respective task (and resulting action).
- the five buttons in group 72 are labeled “Zoom In”, “Zoom Out”, “Add Lesion”, “Freeze Point”, and “Save Point”.
- the “Zoom In” and “Zoom Out” buttons allow the user to adjust the apparent size of the 3D model displayed on monitor 20 (i.e., enlarging or reducing the 3D model on the monitor).
- FIG. 4A is a view of the monitor 20 of FIG. 2 , showing multiple inset displays for different applications, where the display area (window) 52 1 shows the EnSiteTM display output of a 3D electro-anatomic model at a first magnification level.
- FIG. 4B is a further view of monitor 20 , showing a zoomed-in view of the same display area (window), now designated 52 2 , which has an increased magnification level and thus apparent size. This change of course allows the physician to see details in window 52 2 that may not be easy to see in window 52 1 .
- the “Add Lesion” button is configured to add a lesion marker to the 3D model.
- Other commands can be also be executed using the “Freeze Point” and “Save Point” buttons. It should be understood that variations are possible.
- buttons in group 74 are associated with a respective display mode, which alters the display output of system 34 to suit the wishes of the physician.
- the three selectable buttons labeled “Dual View”, “Right View”, and “Map View” re-configure the display output of system 34 , as will appear on monitor 20 .
- buttons in group 76 are associated with a respective viewpoint from which the 3D electro-anatomic model is “viewed” (i.e., as shown in window 52 on monitor 20 ).
- Three of the five selectable buttons namely those labeled “LAO”, “AP”, and “RAO”, allow the user to reconfigure the view point from which the 3D electro-anatomic model is viewed (i.e., left anterior oblique, anterior-posterior, right anterior oblique, respectively).
- the remaining two buttons namely those labeled “Center at Surface” and “Center at Electrode” allow the user to invoke, respectively, the following functions: (1) center the anatomy shape in the middle of the viewing area; and (2) center the current mapping electrode or electrodes in the middle of the viewing area.
- the flattened joystick 78 is a screen object that allows the user to rotate the 3D model displayed in the window 52 .
- the point of contact i.e., physician's finger
- the joystick object 78 moves from the center or neutral position, for example at point 83 , towards the outer perimeter (e.g., through point 84 to point 86 )
- the magnitude of the input action increases.
- the acceleration of rotation of the model or cursor will increase.
- FIG. 3A shows the joystick object 78 as having three (3) gradations or concentric bands, it should be appreciated that this is for clarity only and not limiting in number.
- a relatively larger number of gradations or bands such as ten (10) may be provided so as to effectively provide for a substantially continuous increase in sensitivity (or magnitude) as the point of contact moves toward the outer radius.
- a single gradient may be continuous from the center position, point 83 , to the outer edge of the joystick object 78 , with the centermost portion of the gradient being the brightest in intensity or color and the outermost portion of the gradient being the darkest in intensity or color, for example.
- a single gradient may be continuous from the center position, point 83 , to the outer edge of the joystick object 78 , with the centermost portion of the gradient being the darkest in intensity or color and the outermost portion of the gradient being brightest in intensity or color, for example.
- UI logic 64 can be further configured to present an additional button labeled “Follow Me” (not shown), which, when selected by the user, configures the electro-anatomic mapping system 34 for “follow me” control.
- This style of control is not currently available using a conventional keyboard and mouse interface.
- UI logic 64 is configured to receive a rotation input from the user via the touch panel (e.g., joystick 78 ); however, the received input is interpreted by system 34 as a request to rotate the endocardial surface rendering (the “map”) while maintaining the mapping catheter still or stationary on the display.
- the physician can set the position and orientation of the mapping catheter, where it will remain stationary after the “Follow Me” button is selected.
- computer 26 a includes microphone 66 for capturing speech (audio) and voice recognition logic 68 for analyzing the captured speech to extract or identify spoken commands.
- the voice recognition feature can be used in combination with the touch panel functionality of computer 26 a .
- the microphone 66 may comprise conventional apparatus known in the art, and can be a voice recognition optimized microphone particularly adapted for use in speech recognition applications (e.g., an echo-cancelling microphone).
- Voice recognition logic 68 may comprise conventional apparatus known in the art.
- voice recognition logic 68 may be a commercially available component, such as software available under the trade designation DRAGON DICTATIONTM speech recognition software.
- computer 26 a is configured to recognize a defined set of words or phrases adapted to control various functions of the multiple applications that are accessible or controllable by computer 26 a .
- the voice recognition feature can itself be configured to recognize unique words or phrases to selectively enable or disable the voice recognition feature.
- a button such as button 80 in FIG. 3A , can be used to enable or disable the voice recognition feature.
- the enable/disable button can be either a touch-sensitive button (i.e., screen object), or can be hardware button.
- Voice recognition logic 68 is configured to interact with the physician or other user to “train” the logic (e.g., having the user speak known words) so as to improve word and/or phrase recognition.
- the particulars for each user so trained can be stored in a respective voice (user) profile, stored in memory 62 .
- the currently active voice profile is listed in dashed-line box 89 .
- each user can have unique commands, which may also be stored in the respective voice profile.
- the language need not be English, and can be other languages. This flexibility as to language choice enlarges the audience of users who can use the device 26 a .
- the voice recognition feature presents a number of advantages, including the fact that the physician 16 does not have to remove his/her hands from the catheter or other medical device being manipulated. In addition, the absence of contact or need to touch computer 26 a maintains a sterile condition.
- the voice recognition feature can also be used either alone or in combination with other technologies.
- UI logic 64 also presents a “Settings” button 82 .
- “Settings” button 82 When the “Settings” button 82 is selected, UI logic 64 generates another screen display that allows the user to adjust and/or set/reset various settings associated with the application currently selected.
- the “Settings” button can also allow adjustment of parameters that are more global in nature (i.e., apply to more than one application). For example only, through “Settings”, the physician or another user can edit all of the phrases associated with a particular physician or specify a timeout (i.e., the elapsed amount of time, after which the computer will stop listening (or not) for voice commands). The physician or another user can also edit miscellaneous parameters, such as communication settings and the like.
- FIG. 3B is an isometric view of a sterile drape 88 configured to protect the touch panel computer 26 a of FIG. 3A from contamination and to maintain the physician's sterility. Conventional materials and construction techniques can be used to make drape 88 .

- buttons are shown, grouped by function, for example the signals-adjustment group 92 , the events group 94 , the timer group 96 and the print group 98 . It should be understood that variations are possible, depending on the items that can be adjusted or controlled on the destination system. It warrants emphasizing that UI logic 64 thus presents a unique user interface tailored to the requirements of the particular application selected. Each group includes items that are commonly asked for by the physician.
- the Speed +/ ⁇ buttons can be used to change the viewed waveform sweep speed as the physician may need more or less detail; the Page +/ ⁇ buttons can be used to change the page of signals being viewed (e.g., from surface ECG signals to intracardiac signals); and the Amplitude +/ ⁇ buttons can be used to change the signal amplitudes up or down.
- the enumerated Events buttons cause a mark to be created in the patient charting log to indicate a noteworthy (i.e., important) item or event, such as the patient was just defibrillated or entered a tachy-arrhythmia.
- the timer buttons can be used to keep track of such periods of time, for example, such as a certain time after an ablation (e.g., 30 minutes) to verify that the ablation procedure is still effective.
- various print buttons are provided so as to avoid requiring a physician to verbally indicate (e.g., by way of shouting out “print that document to the case” or the like) and to include such documents in a final report.

- the output motion data generated by motion capture apparatus 26 d may comprise imaging data.
- a skeleton 138 a shows the respective positions of two fiducial points at 140 3 and 140 4 corresponding to the separated hands of the user.
- Gesture recognition logic 134 is configured to determine the position of the user's hands, and also a distance 142 between the user's hands.
- the position and distance between the user's hands can be translated by interpreter logic 136 to a robotic catheter control command.
- the position and distance between the user's hands can be used to control the degree of extension or retraction of a catheter and/or a sheath along a respective translation axis.
- a robotic catheter control command may have a characteristic that corresponds to the magnitude of the action that is to be initiated by the command.
- the magnitude of the action may be defined by the distance between preselected fiducial points.
- the action may be a catheter extension, a catheter retraction, a sheath extension, and a sheath retraction.
- a skeleton 138 b shows a sequence of time-based positions traversed by a single fiducial point (joint 140 4 ) during the rotation of a user's wrist.
- the time-based positions of the tracked fiducial point (joint 140 4 ) at times t 1 , t 2 , t 3 , t 4 and t 5 are designated 140 4-1 , 140 4-2 , 140 4-3 , 140 4-4 , and 140 4-5 respectively.
- gesture recognition logic 134 can determine the extent of the rotation, as indicated by rotation angle 144 .
- gesture recognition logic 134 recognizes the rotational motion while interpreter logic 136 translates this gesture into an output command, for example only, to actuate rotation of a catheter and/or a sheath.
- Interpreter logic 136 can be configured to generate the output rotation command further as a function of the determined rotation angle 144 (i.e., the extent of actual catheter and/or sheath rotation can be made to correspond to the determined rotation angle 144 ).
- the fiducial point tracking data output from motion capture apparatus 26 d therefore includes, for each fiducial point, a respective time-based plurality of positions.
- a robotic catheter control command may have a characteristic that corresponds to the rotation associated with the action to be initiated by the command.
- the rotation may be defined by the rotation angle through which the preselected fiducial point rotates.
- the action may be a catheter or sheath rotation.
- gesture recognition logic 134 can be additionally configured to identify and track a wand (e.g., part or all of electronic wand system 26 b described above), a baton or a like implement being held in the hand of the user.
- a wand e.g., part or all of electronic wand system 26 b described above
- baton or a like implement being held in the hand of the user.
- the use of such implements can improve the ability of the motion capture apparatus 26 d to track the user's wrist motion (rotation).
- a wand being generally larger and more distinct than a wrist fiducial point (joint), can be expected to provide a correspondingly larger object in the imaging data and/or other data provided by the motion capture apparatus 26 d . This effectively provides greater resolution and robustness in the tracking functionality of motion capture apparatus 26 d /gesture recognition logic 134 .
- Gesture recognition logic 134 may be configured to operate as described below to recognize a 3D gesture.
- gesture recognition logic 134 is configured to identify a start pose based on the fiducial point tracking data.
- the start pose may correspond to a start condition where a first set of fiducial points assumes a first relationship therebetween. For example, this condition may be satisfied when the fiducial points form a first predetermined “constellation”.
- gesture recognition logic 134 is configured to record the motion of a predetermined plurality of fiducial points after recognition of the start pose, and continue recording until an end pose is identified, which identification is also based on the fiducial tracking data.
- the end pose may correspond to an end condition where a second set of fiducial points assume a second relationship therebetween. For example, this condition may be satisfied when the fiducial points form a second predetermined “constellation”.
- gesture recognition logic 134 is configured to compare the recorded motion of the predetermined plurality of fiducial points (being tracked) with a plurality of predefined gestures. Each predefined gesture is itself defined by a respective motion of a respective set of fiducial points. Finally, gesture recognition logic 134 is configured to output one of the plurality of predefined gestures as the recognized gesture when the recorded motion matches one of the predefined gestures (i.e., the recognized gesture being the one that matches the recorded motion).
- System 127 may also include various safety features. As described above, motion capture apparatus 26 d is generally responsive to activity occurring within sensing volume 122 . In an embodiment, motion capture apparatus 26 d /gesture recognition logic 134 can be configured to be responsive only to activity in a smaller 3D volume included within sensing volume 122 (hereinafter an “action box”). The purpose of the action box is that once it is defined, system 127 will only respond to actions that occur within the action box. For example, a user can only actuate the robotic catheter system by placing his hands in the action box or otherwise causing some activity to occur in the action box. This arrangement can be expected to reduce the occurrence of unintended actuation, thereby improving safety.
- the action box of sensing volume 122 can be positioned above a patient table (see FIG. 2 , which shows a patient table and patient), in a control room, for example, control area/room 12 in FIG. 1 , or in various other locations.
- system 127 can be configured to allow the user to adjust either or both of the size and location of the action box relative to motion capture apparatus 26 d .
- motion capture apparatus 26 d will only respond to activities occurring within the action box, and ignore all other activity outside the action box.
- Staff can be trained to never place their hands or any other object into the action box as it is strictly for use by a trained physician because of the potential to actuate functionality of a medical device.
- the action box can be delineated by a visible construct, such as a frame.
- the frame can be made of solid material, in which case is also presents a physical construct, or the outlines of the frame can be illuminated, for example, via low intensity laser beams.
- system 127 can be configured to include a user-actuatable switch such as a dead-man switch 146 .
- Switch 146 may include a normally open state and a user-actuatable closed state.
- System 127 can be configured to be active only when the dead-man switch 146 has been closed by the user.
- System 127 may only respond to user actions (gestures) when the switch 146 has been actuated.
- system 127 may be configured to at least disable communication of a robotic control command to the robotic catheter system unless switch 146 is in the closed state.
- the dead-man switch 146 may comprise a switch on a wand, a foot pedal, or the like.
- motion capture mechanisms can be used.
- alternatives include an optical-based position tracking product (e.g., object or fiducial tracking system) known by the trade designation as the POLARIS® system and a magnetic-field based product known by the trade designation as the AURORA® system, both from Northern Digital Inc.
- object or fiducial tracking system e.g., object or fiducial tracking system
- AURORA® system e.g., AURORA® system
- FIG. 17 shows a further embodiment involving hand motion tracking where a user input device 1000 can include a spatially detected glove or stylus.
- the user's/wearer's index finger can be instrumented with various sensors 1040 (e.g., position and orientation sensors, and/or accelerometers).
- the glove or stylus input device can be locatable in 3-D space through the use of a positioning system employing a magnetic field, an electrostatic field, or through the use of an optical positioning system.
- the positioning system can be implemented within a liquid tank (e.g., water tank), where field generators, such as those associated with the EnSiteTM NavXTM control system (a product of St. Jude Medical), are externally attached.
- an instrumented glove or stylus can extend into the tank while, for example, the user's finger (e.g., index finger), or stylus can be instrumented with electrodes configured to measure parameters of the electric field.
- the construction and/or placement of the sensors e.g., EnSiteTM NavXTM-type electrodes
- the positioning system can be implemented using a magnetic positioning system.
- a magnetic positioning system 1070 can operate, for example, by emitting several magnetic fields 1072 a - 1074 c from an array of field generators 1074 a - 1074 c .
- Sensor coils e.g., sensors 1040 or 1052
- a processor 1080 can be able to resolve the sensor's position and orientation relative to each field generator or to a fixed reference sensor. Detected changes in the position and orientation of the glove or stylus sensor can then be registered and user motion data can be determined, and passed on to gesture recognition logic 134 .
- a haptic glove (not shown) with sensors can be provided in order to capture user motion, to thereby allow recognition of user gestures, as seen by reference to U.S. application Ser. No. 12/507,175, filed 22 Jul. 2009 (published as United States patent application publication no. US 2010/0073150 A1), and hereby incorporated by reference as though fully set forth herein.
- a haptic glove can output data that allows detection of the relative bending of the fingers and joints within the hand.
- Various motions of the hand can be indicators of desired motion to be input into the robotic catheter system.
- a haptic glove or similar devices have the potential to detect motion relative to itself, but not absolute motion relative to the physical (real) world. In an embodiment and referring again to FIGS.
- a hybrid motion capture system wherein a haptic glove is configured to simultaneously provide relative motion such as finger bending as described above combined with an absolute location device, such as motion capture apparatus 26 d , to form composite motions or gestures (using input from both systems).
- Such composite motions can be provided to gesture recognition logic 134 and interpreter logic 136 to output corresponding robotic catheter control commands, for effecting precise motions of the catheter and/or sheath of the robotic catheter system.
- user-provided gestures can also be captured and used to control other electrophysiological systems, such an electro-anatomic mapping and visualization system (e.g., an EnSiteTM VelocityTM system).
- an electro-anatomic mapping and visualization system e.g., an EnSiteTM VelocityTM system
- system 127 can be configured with context switching functionality. In other words, system 127 is configured to determine when a gesture is intended to control one target system such as the robotic catheter system versus another target system such as an electro-anatomic mapping and visualization system.
- system 127 is configured to analyze the actions occurring within a context switching box 148 , shown in FIG. 15 .
- context switching box 148 may be located near the corner of sensing volume 122 .
- system 127 is configured to detect when the user is “tapping” in context switching box 148 .
- context switching box 148 switches context (i.e., from the robotic catheter system as the target to the mapping system as the target) and thereafter allows user input to control an electro-anatomic mapping system target, such as the EnsiteTM VelocityTM system.
- the act of tapping may involve the user holding his or her hand in a particular location and then ballistically moving the fingers back and forth.
- This tapping motion when detected by gesture recognition logic 134 , causes an electro-anatomic system, such as system 34 — FIG. 2 , to display a context menu visible to the user.
- a context menu may have a series of selectable options in a “drop-down” style box.
- Gesture recognition logic 134 can be further configured to recognize a second tapping motion, which finalizes the selection and closes the context menu. While the gesture itself can be captured using system 127 , other detection mechanisms, such as through the use of various sensors as described above (e.g., haptic glove, accelerometer disposed within a glove, a wand, etc.) can be alternatively used.
- system 127 may include context switching logic (not shown) stored in memory 132 and configured for execution in the one or more processors 130 .
- the context switching logic may be configured to detect a predetermined context switching gesture (e.g., the “tapping” gesture described above) based on the output data from motion capture apparatus 26 d , but only where the context switching gesture occurs in the context switching portion of sensing volume 122 .
- a context switching gesture e.g., the “tapping” gesture described above
- the context switching logic may set a context switch parameter or the like.
- Interpreter logic 136 is accordingly configured to selectively translate, based on the state of the context switch parameter, the recognized user gesture into one of either (i) a robotic catheter control command, or (ii) an electro-anatomic mapping system control command.
- further visual feedback can be displayed on the display of the electro-anatomic system 34 , such as on the display area 52 in FIG. 2 , showing the relative motion of the user's hands and fingers.
- This feedback can be through the use of a (i) special-purpose mouse pointer in addition to and visibly distinguishable from a primary mouse pointer, (ii) a graphical representation of the hands, or the like.
- system 127 can be used in combination with an electro-anatomic system 34 ( FIG. 2 ) and further in combination with a three-dimensional (3D) display, such as that described in U.S. application No. 61/643,667, filed 7 May 2012, and hereby incorporated by reference as though fully set forth herein.
- This combination of functions allows for a virtual representation of the hands that could be rendered and displayed within a three-dimensional (3D) window along with representations of the catheters and/or sheaths, all with respect to a heart model.
- This 3D window may allow the user to perceive his or her own hands reaching into the heart of the patient.
- the user could “grab” the catheter and move it to a new location, for example, to a target location.
- the virtual hands can be moved near the tip of one of the catheters, and by “pinching” on the tip of the catheter, the user can “grab and pull” the catheter in different directions.
- the target location can be specified as the location to which the rendered catheter is pulled by the user. Once the target location has been specified, this information can be passed on to the robotic control system 210 by interpreter logic 136 , wherein robotic control system 210 processes this target location as a dynamic waypoint, and thereafter automatically move the catheter to such target location.
- the foregoing combination including a 3D display, provides an intuitive way for a user to manipulate a medical device within the heart.
- interpreter logic 136 can be configured to generate different commands based on the same user gesture.
- Interpreter logic 136 is configured to analyze the recognized use gesture in light of and as a function of the orientation of the then-visible (current) view of an anatomical model being displayed by an electro-anatomic system, such as system 34 ( FIG. 2 ).
- the effect of the user gesture can be view relative, such that the same gesture can actuate different, relative motions based on the current view angle or orientation displayed by the electro-anatomic system 34 .
- the direction of translation can be different based on the current view, as shown in the examples in Table 1.
- RCGS 210 can be likened to power steering for a catheter system.
- the RCGS 210 can be used, for example, to manipulate the location and orientation of catheters and sheaths in a heart chamber or in another body cavity or lumen.
- the RCGS 210 thus provides the user with a similar type of control provided by a conventional manually-operated system, but allows for repeatable, precise, and dynamic movements.
- a user such as an electrophysiologist can identify locations (potentially forming a path) on a rendered computer model of the cardiac anatomy.
- the system can be configured to relate those digitally selected points to positions within a patient's actual/physical anatomy, and can thereafter command and control the movement of the catheter to the defined positions. Once at the specified target location, either the user or the system can perform the desired diagnostic or therapeutic function.
- the RCGS 210 enables full robotic navigation/guidance and control.
- the RCGS 210 can generally include one or more monitors or displays 212 , a visualization, mapping and navigation (including localization) system 214 , a human input device and control system (referred to as “input control system”) 224 , an electronic control system 226 , a manipulator assembly 300 for operating a device cartridge 400 , and a manipulator support structure 500 for positioning the manipulator assembly 300 in proximity to a patient or a patient's bed.

- an electronic control system 226 a manipulator assembly 300 for operating a device cartridge 400
- manipulator support structure 500 for positioning the manipulator assembly 300 in proximity to a patient or a patient's bed.
- Displays 212 are configured to visually present to a user information regarding patient anatomy, medical device location or the like, originating from a variety of different sources.
- Displays 212 can include (1) an EnSiteTM VelocityTM monitor 216 (coupled to system 214 —described more fully below) for displaying cardiac chamber geometries or models, displaying activation timing and voltage data to identify arrhythmias, and for facilitating guidance of catheter movement; (2) a fluoroscopy monitor 218 for displaying a real-time x-ray image or for assisting a physician with catheter movement; (3) an intra-cardiac echo (ICE) display 220 to provide further imaging; and (4) an EP recording system display 222 .
- ICE intra-cardiac echo
- the system 214 is configured to provide many advanced features, such as visualization, mapping, navigation support and positioning (i.e., determine a position and orientation (P&O) of a sensor-equipped medical device, for example, a P&O of a distal tip portion of a catheter).
- Such functionality can be provided as part of a larger visualization, mapping and navigation system, for example, an EnSiteTM VelocityTM system running a version of EnSiteTM NavXTM software commercially available from St. Jude Medical, Inc., of St. Paul, Minn. and as described above.
- System 214 can thus comprise conventional apparatus, for example, the EnSiteTM VelocityTM system, or other known technologies for locating/navigating a catheter in space (and for visualization), including for example, the CARTO visualization and location system of Biosense Webster, Inc., the AURORA® system of Northern Digital Inc., a magnetic field based localization system such as the MediGuideTM Technology, a system based on technology from MediGuide Ltd. of Haifa, Israel and now owned by St. Jude Medical, Inc., or a hybrid magnetic field-impedance based system, such as the CARTO 3 visualization and location system of Biosense Webster, Inc.

- a target point may 1120 be initially set by taping on screen in a position where a target point is desired. Once a point has been set, it may be subsequently selected by re-tapping on the point. When a point is “selected,” it may change appearance, such as selected point 1122 .
- the user may for example, select it by tapping it, and then drag the point to a new location. Additionally, after selecting a point, the software may call up a list of menu options that may allow the user to configure or view one or more parameters of the point.

- The instant disclosure relates generally to electrophysiology lab integration, and more particularly to user interfaces and devices therefore for robotic control of electrophysiology lab diagnostic and therapeutic equipment.
- It is known to provide an electrophysiology lab in a medical facility. Such a lab may have use of a wide variety of diagnostic and therapeutic equipment useful in rendering medical service to a patient, such as imaging systems (e.g., fluoroscopy, intracardiac echocardiography, etc.), an electro-anatomic visualization, mapping and navigation system, ablation energy sources (e.g., radio frequency (RF) ablation generator), a recording system (e.g., for ECG, cardiac signals, etc.), a cardiac stimulator and the like. In a typical configuration, as seen by reference to
FIG. 1 , a procedure room 10 (i.e., a sterile environment) may have an associated control area orroom 12, which is commonly outfitted with one or more control stations 14 1, 14 2, . . . 14 n that are operated by one or more control technicians. Each control station may include a respective display monitor, keyboard and mouse for use by the technician. Depending on the lab setup, the control station(s) may be across the room, or outside of theprocedure room 10 completely, perhaps configured with a common window to allow the technician(s) to observe the procedure room through the window. These control station(s) allow access to and may be used to control the diagnostic and therapeutic equipment mentioned above. - In conventional practice, an electrophysiology (EP)
physician 16 is scrubbed into a sterile procedure and typically manipulates one or more catheters (not shown) in a sterile drape covered body of thepatient 18. The physician's sterile gloved hands are typically engaged with the catheter handle and shaft next to the patient and he or she is therefore unable to directly make changes himself to any of the EP systems. Theprocedure room 10 typically includes one or more monitors (e.g., an integratedmulti-display monitor 20 is shown) arranged so that thephysician 16 can see themonitor 20 on which is displayed various patient information being produced by the diagnostic and therapeutic equipment mentioned above. InFIG. 1 , multiple applications, for example, an electro-anatomic mapping application (e.g., EnSite™ Velocity™) and an EP signal acquisition and recording application, direct a visual output to a respective display area ofmonitor 20. When changes to an application are needed, thephysician 16 verbalizes such commands to the control technicians in the control area/room 12 who are working at the various control stations 14 1, 14 2, . . . 14 n. The multiple technicians at multiple control stations use multiple keyboard/mouse sets to control the multiple applications. The verbal commands between the physician and the technician occur throughout the procedure. - For example, the
EP physician 16 can verbally communicate (i.e., to the control technician—a mapping system operator) the desired view of the map to be displayed, when to collect points, when to separate anatomic locations, and other details of creating and viewing an anatomic map. TheEP physician 16 can also communicate which signal traces to show, the desired amplitude, when to drop a lesion marker, and when to record a segment, to name a few. Where the technician is in a separate room, communication can be facilitated using radio. - While some commands are straightforward, for example, “LAO View”, “record that” and “stop pacing”, other commands are not as easy to clearly communicate. For example, how much rotation of a model the command “rotate a little to the right” means can be different as between the physician and the technician. This type of command therefore involves a question of degree. Also, depending on the physician-technician relationship, other requests related to the mapping system views and setup can be misinterpreted. For example, a request to “rotate right” may mean to rotate the model right (i.e., rotate view left) when originating from one physician but can alternatively mean rotate view right (i.e., rotate model left) when coming from another physician. This type of command therefore involves physician-technician agreement as to convention. Furthermore, implementation of requests for event markers, segment recordings, lesion markers and the like can be delayed by the time it takes the technician to hear, understand and act on a physician's command. Ambient discussions and/or equipment noise in and around the EP lab can increase this delay.
- Certain catheter procedures can be performed through the use of a remote catheter guidance system (RCGS), which employs robotically-controlled movement of the catheter. The robotic control can receive input command through a user interface that can include a joystick, mouse or the like. However, there is a need for an improved user interface to control an RCGS.
- The foregoing discussion is intended only to illustrate the present field and should not be taken as a disavowal of claim scope.
- One advantage of the methods and apparatuses described, depicted and claimed herein is that they provide an EP physician or other user with the capability of directly controlling a robotic catheter system. In an embodiment, a system for enabling a user to remotely control a robotic catheter system includes a motion capture apparatus and an electronic control unit. The motion capture apparatus is configured to capture motion of a user in a sensing volume and generate output data indicative of the captured user motion. The electronic control unit includes one or more processors and memory. The system further includes gesture recognition logic stored in the memory and configured to execute on the one or more processors. The gesture recognition logic is configured to recognize a user gesture based on the output data generated by the motion capture apparatus. The system further includes interpreter logic stored in the memory and configured to be executed by the one or more processors. The interpreter logic is configured to translate the recognized user gestures to a corresponding robotic catheter control command wherein the command is configured to control an aspect of the operation of the robotic catheter system. The electronic control unit is configured to communicate the command to the robotic catheter system.
- In an embodiment, the motion capture apparatus is configured to acquire imaging of the movements of the user. For example only, the motion capture apparatus provides the capability of receiving input by way of physician gestures (e.g., hand, arm, leg, trunk, facial, etc.).
- In an embodiment, the user motion data includes fiducial point tracking data, and wherein the gesture recognition logic is configured to identify a start pose based on fiducial point tracking data, record the motion a predetermined plurality of fiducial points after the start pose until an end pose is identified based on the fiducial point tracking data, compare the recorded motion of the predetermined plurality of fiducial points with a plurality of predefined gestures, and output the user gesture when the recorded motion matches one of the plurality of gestures.
- The foregoing and other aspects, features, details, utilities, and advantages of the present disclosure will be apparent from reading the following description and claims, and from reviewing the accompanying drawings.

Means orapparatus 24 provides the mechanism for theEP physician 16 to directly interact with such systems without the need for the intermediate step of verbalizing commands to a control technician, as described in connection withFIG. 1 . In this regard,bedside interface device 26 is configured to present a user interface or other input logic with which the user (e.g., the EP physician 16) can directly interact or from which an input can be acquired. In multiple embodiments, various modes of interaction are presented, such as interaction via a user touch, a user multi-touch, a user gesture, a verbal command, a motion pattern of a user-controlled device, a user motion pattern and a user electroencephalogram. In addition,bedside interface device 26 can be configured to communicate with one or more of the diagnostic/therapeutic systems either wirelessly (as shown) or via a wired connection (not shown). - The
base interface 28 is configured to interpret and/or facilitate directing the input acquired by thebedside interface device 26 to the appropriate one or more diagnostic and/or therapeutic systems (e.g., an electro-anatomic mapping system). In an embodiment,base interface 28 is centralized (as shown), wherein all communications withbedside device 26 occur throughbase interface 28. In a further embodiment,base interface 28 may be functionally distributed, wherein interface functions are located within each diagnostic or therapeutic system. In a still further embodiment, communications betweenbedside interface 26 and certain ones of the diagnostic/therapeutic systems can be centralized, while communications with other ones of the diagnostic/therapeutic systems can occur directly (i.e., separately). - The means or
apparatus 24 addresses a number of the shortcomings of the conventional practice as described in the Background. For example, means orapparatus 24 allows theEP physician 16 to directly input levels of degree, for example, how much to rotate a view, as opposed to trying to verbally communicate “how much” to a control technician. Further, the use of means orapparatus 24 avoids the potential confusion that can sometimes occur between the EP physician and the control technician as to convention (i.e., does “rotate right” mean rotate the view or the model?). In addition, the use of means orapparatus 24 reduces or eliminates the inherent time delay between the time when the EP physician verbally issues a command and the time when the command is understood and acted upon by the technician. - With continued reference to
FIG. 2 , thephysician 16 will typically have access to a plurality of diagnostic and/or therapeutic systems in order to perform one or more medical procedures. In the illustrative embodiment, thephysician 16 may have access to a first imaging system, such as afluoroscopic imaging system 30, a second imaging system, such as an intracardiac ultrasound or echocardiography (ICE)imaging system 32, an electro-anatomic positioning, mapping, andvisualization system 34, a further positioning system, such as a medical positioning system (magnetic-field based) 36, a patient data (electrophysiological (EP) data) monitoring andrecording system 38, acardiac stimulator 40, an EP data editing/monitoring system 42 and anablation system 44.FIG. 2 schematically shows acommunication mechanism 46 which facilitates communication between and among the various systems described above. It should be understood, however, that thecommunications mechanism 46 may not necessarily function to enable communications between each and every system shown. - The
fluoroscopic imaging system 30 may comprise conventional apparatus known in the art, for example, single plane or bi-plane configurations. Adisplay area 48 that is shown onmonitor 20 corresponds to the display output offluoroscopic imaging system 30. - The intracardiac ultrasound and/or intracardiac echocardiography (ICE)
imaging system 32 may also comprise conventional apparatus known in the art. For example, in one embodiment, thesystem 32 may comprise a commercial system available under the trade designation ViewMate™ Z intracardiac ultrasound system compatible with a ViewFlex™ PLUS intracardiac echocardiography (ICE) catheter, from St. Jude Medical, Inc. of St. Paul, Minn., USA. Thesystem 32 is configured to provide real-time image guidance and visualization, for example, of the cardiac anatomy. Such high fidelity images can be used to help direct diagnosis or therapy during complex electrophysiology procedures. Adisplay area 50 that is shown onmonitor 20 corresponds to the display output of theultrasound imaging system 32. - The
system 34 is configured to provide many advanced features, such as visualization, mapping, navigation support and positioning (i.e., determine a position and orientation (P&O) of a sensor-equipped medical device, for example, a P&O of a distal tip portion of a catheter). Such functionality can be provided as part of a larger visualization, mapping and navigation system, for example, an EnSite™ Velocity™ cardiac electro-anatomic mapping system running a version of EnSite™ NavX™ navigation and visualization technology software commercially available from St. Jude Medical, Inc., of St. Paul, Minn. and as also seen generally by reference to U.S. Pat. No. 7,263,397 (the '397 patent), or U.S. Pat. No. 7,885,707 (the '707 patent). The '397 patent and the '707 patent are both hereby incorporated by reference as though fully set forth herein.System 34 can be configured to perform further advanced functions, such as motion compensation and adjustment functions. Motion compensation may include, for example, compensation for respiration-induced patient body movement, as described in U.S. application Ser. No. 12/980,515, filed 29 Dec. 2010, which is hereby incorporated by reference as though fully set forth herein.System 34 can be used in connection with or for various medical procedures, for example, EP studies or cardiac ablation procedures. -
System 34 is further configured to generate and display three dimensional (3D) cardiac chamber geometries or models, display activation timing and voltage data to identify arrhythmias, and to generally facilitate guidance of catheter movement in the body of the patient. For example, adisplay area 52 that is shown onmonitor 20 corresponds to the display output ofsystem 34, can be viewed byphysician 16 during a procedure, which can visually communicate information of interest or need to the physician. Thedisplay area 52 inFIG. 2 shows a 3D cardiac model, which, as will be described below in greater detail, may be modified (i.e., rotated, zoomed, etc.) pursuant to commands given directly byphysician 16 via thebedside interface device 26. -
System 36 is configured to provide positioning information with respect to suitably configured medical devices (i.e., those including a positioning sensor).System 36 may use, at least in part, a magnetic field based localization technology, comprising conventional apparatus known in the art, for example, as seen by reference to U.S. Pat. No. 7,386,339 (the '339 patent), U.S. Pat. No. 6,233,476 (the '476 patent), and U.S. Pat. No. 7,197,354 (the '354 patent). The '339 patent, the '476 patent, and the '354 patent are all hereby incorporated by reference as though fully set forth herein.System 36 may comprise MediGuide™ Technology, a medical positioning system commercially offered by MediGuide Ltd. of Haifa, Israel and now owned by St. Jude Medical, Inc. of St. Paul, Minn., USA.System 36 may alternatively comprise variants, which employ magnetic field generator operation, at least in part, such as a combination magnetic field and current field-based system such as the CARTO™ 3 System available from Biosense Webster, and as generally shown with reference to one or more of U.S. Pat. Nos. 6,498,944, 6,788,967 and 6,690,963, the entire disclosures of each of the foregoing being incorporated herein by reference as though fully set forth herein. - EP monitoring and
recording system 38 is configured to receive, digitize, display and store electrocardiograms, invasive blood pressure waveforms, marker channels, and ablation data.System 38 may comprise conventional apparatus known in the art. In one embodiment,system 38 may comprise a commercially available product sold under the trade designation EP-WorkMate™ from St. Jude Medical, Inc. of St. Paul, Minn., USA. Thesystem 38 can be configured to record a large number of intracardiac channels, may be further configured with an integrated cardiac stimulator (shown inFIG. 2 as stimulator 40), as well as offering storage and retrieval capabilities of an extensive database of patient information.Display areas monitor 20 correspond to the display output of EP monitoring andrecording system 38. -
Cardiac stimulator 40 is configured to provide electrical stimulation of the heart during EP studies.Stimulator 40 can be provided in either a stand-alone configuration, or can be integrated with EP monitoring andrecording system 38, as shown inFIG. 2 .Stimulator 40 is configured to allow the user to initiate or terminate tachy-arrhythmias manually or automatically using preprogrammed modes of operation.Stimulator 40 may comprise conventional apparatus known in the art. In an embodiment,stimulator 40 can comprise a commercially available cardiac stimulator sold under the trade designation EP-4™ available from St. Jude Medical, Inc. of St. Paul, Minn., USA. Thedisplay area 58 shown onmonitor 20 corresponds to the display output of thecardiac stimulator 40. - EP data editing/
monitoring system 42 is configured to allow editing and monitoring of patient data (EP data), as well as charting, analysis, and other functions.System 42 can be configured for connection to EPdata recording system 38 for real-time patient charting, physiological monitoring, and data analysis during EP studies/procedures.System 42 may comprise conventional apparatus known in the art. In an embodiment,system 42 may comprise a commercially available product sold under the trade designation EP-NurseMate™ available from St. Jude Medical, Inc. of St. Paul, Minn., USA. - To the extent the medical procedure involves tissue ablation (e.g., cardiac tissue ablation),
ablation system 44 can be provided. Theablation system 44 may be configured with various types of ablation energy sources that can be used in or by a catheter, such as radio-frequency (RF), ultrasound (e.g. acoustic/ultrasound or HIFU), laser, microwave, cryogenic, chemical, photo-chemical or other energy used (or combinations and/or hybrids thereof) for performing ablative procedures. RF ablation embodiments may and typically will include other structure(s) not shown inFIG. 2 , such as one or more body surface electrodes (skin patches) for application onto the body of a patient (e.g., an RF dispersive indifferent electrode/patch), an irrigation fluid source (gravity feed or pump), and an RF ablation generator (e.g., such as a commercially available unit sold under the model number IBI-1500T RF Cardiac Ablation Generator, available from St. Jude Medical, Inc.). -
FIG. 3A is a plan view of a first embodiment of a bedside interface device comprising acomputer 26 a, suitable for use in the EP lab ofFIG. 2 , and showing a first application-specific user interface. Thecomputer 26 a includes a touch-responsive display panel and thus may be referred to hereinafter sometimes as a touch panel computer. Thetouch panel computer 26 a, as shown in inset inFIG. 3A , includes an electronic control unit (ECU) having aprocessor 60 and a computer-readable memory 62, user interface (UI) logic 64 stored in thememory 62 and configured to be executed byprocessor 60, amicrophone 66 andvoice recognition logic 68. In an embodiment,voice recognition logic 68 is also stored inmemory 62 and is configured to be executed byprocessor 60. In an embodiment, thetouch panel computer 26 a is configured for wireless communication to base interface 28 (best shown inFIG. 2 ). In addition, thetouch panel computer 26 a is configured to draw operating power at least from a battery-based power source—eliminating the need for a power cable. The resulting portability (i.e., no cables needed for either communications or power) allowstouch panel computer 26 a to be carried around by theEP physician 16 or other lab staff to provide control over the linked systems (described below) while moving throughout theprocedure room 10 or even thecontrol room 12. In another embodiment,touch panel computer 26 a can be wired for one or both of communications and power, and can also be fixed to the bedrail or in the sterile field. - In the illustrated embodiment, the UI logic 64 is configured to present a plurality of application-specific user interfaces, each configured to allow a user (e.g., the EP physician 16) to interact with a respective one of a plurality of diagnostic and/or therapeutic systems (and their unique interface or control applications). As shown in
FIG. 3A , the UI logic 64 is configured to present on the touch panel surface ofcomputer 26 a a plurality of touch-sensitive objects (i.e., “buttons”, “flattened joystick”, etc.), to be described below. In the illustrative embodiment, the UI logic 64 produces a first, application-selection group of buttons, designated asgroup 70, and which are located near the top of the touch panel. Each of the buttons ingroup 70 are associated with a respective diagnostic and/or therapeutic system (and control or interface application therefore). For example, the six buttons labeled “EnSite”, “WorkMate”, “EP4”, “NurseMate”, “MediGuide”, “ViewMate” correspond to electro-anatomic mapping system 34 (for mapping control), EP recording system 38 (for patient data recording control), stimulator 40 (for stimulator control), EP data editing and monitoring system 42 (for charting) and ultrasound imaging system 32 (for ultrasound control), respectively. - When a user selects one of the buttons in
group 70, the UI logic 64 configures the screen display ofcomputer 26 a with an application-specific user interface tailored for the control of and interface with the particular EP system selected by the user. InFIG. 3A , the “EnSite” system is selected, so the UI logic 64 alters the visual appearance of the “EnSite” button so that it is visually distinguishable from the other, non-selected buttons ingroup 70. For example, when selected, the “EnSite” button may appear depressed or otherwise shaded differently than the other, non-selected buttons ingroup 70. This always lets the user know what system is selected. The UI logic 64, in an embodiment, also maintains the application-selection buttons ingroup 70 at the top of the screen regardless of the particular application selected by the user. This arrangement allows the user to move from system (application) to system (application) quickly and control each one independently. - With continued reference to
FIG. 3A , UI logic 64 presents an application-specific user interface tailored and optimized for control of and interaction withsystem 34. This user interface includes a second, common-task group of selectable buttons, designatedgroup 72, a third, view-mode group of selectable buttons, designatedgroup 74, a fourth, view-select group of selectable buttons, designatedgroup 76, a flattenedjoystick 78 configured to receive view-manipulation input from the user, a voicerecognition control button 80, and asettings button 82. Each group will be addressed in turn. - The
second group 72 of buttons includes a listing of common tasks performed by an EP physician when interacting withsystem 34. Each of the buttons ingroup 72 are associated with a respective task (and resulting action). For example, the five buttons ingroup 72 are labeled “Zoom In”, “Zoom Out”, “Add Lesion”, “Freeze Point”, and “Save Point”. The “Zoom In” and “Zoom Out” buttons allow the user to adjust the apparent size of the 3D model displayed on monitor 20 (i.e., enlarging or reducing the 3D model on the monitor). - For example,
FIG. 4A is a view of themonitor 20 ofFIG. 2 , showing multiple inset displays for different applications, where the display area (window) 52 1 shows the EnSite™ display output of a 3D electro-anatomic model at a first magnification level.FIG. 4B is a further view ofmonitor 20, showing a zoomed-in view of the same display area (window), now designated 52 2, which has an increased magnification level and thus apparent size. This change of course allows the physician to see details inwindow 52 2 that may not be easy to see inwindow 52 1. - Referring again to
FIG. 3A , the “Add Lesion” button is configured to add a lesion marker to the 3D model. Other commands can be also be executed using the “Freeze Point” and “Save Point” buttons. It should be understood that variations are possible. - Each of the buttons in
group 74 are associated with a respective display mode, which alters the display output ofsystem 34 to suit the wishes of the physician. For example, the three selectable buttons labeled “Dual View”, “Right View”, and “Map View” re-configure the display output ofsystem 34, as will appear onmonitor 20. - Each of the buttons in
group 76 are associated with a respective viewpoint from which the 3D electro-anatomic model is “viewed” (i.e., as shown inwindow 52 on monitor 20). Three of the five selectable buttons, namely those labeled “LAO”, “AP”, and “RAO”, allow the user to reconfigure the view point from which the 3D electro-anatomic model is viewed (i.e., left anterior oblique, anterior-posterior, right anterior oblique, respectively). The remaining two buttons, namely those labeled “Center at Surface” and “Center at Electrode” allow the user to invoke, respectively, the following functions: (1) center the anatomy shape in the middle of the viewing area; and (2) center the current mapping electrode or electrodes in the middle of the viewing area. - The flattened
joystick 78 is a screen object that allows the user to rotate the 3D model displayed in thewindow 52. In addition, as the point of contact (i.e., physician's finger) with thejoystick object 78 moves from the center or neutral position, for example at point 83, towards the outer perimeter (e.g., throughpoint 84 to point 86), the magnitude of the input action increases. For example, the acceleration of rotation of the model or cursor will increase. WhileFIG. 3A shows thejoystick object 78 as having three (3) gradations or concentric bands, it should be appreciated that this is for clarity only and not limiting in number. For example, in an embodiment, a relatively larger number of gradations or bands, such as ten (10), may be provided so as to effectively provide for a substantially continuous increase in sensitivity (or magnitude) as the point of contact moves toward the outer radius. In another embodiment, a single gradient may be continuous from the center position, point 83, to the outer edge of thejoystick object 78, with the centermost portion of the gradient being the brightest in intensity or color and the outermost portion of the gradient being the darkest in intensity or color, for example. In yet another embodiment, a single gradient may be continuous from the center position, point 83, to the outer edge of thejoystick object 78, with the centermost portion of the gradient being the darkest in intensity or color and the outermost portion of the gradient being brightest in intensity or color, for example. - In a further embodiment, UI logic 64 can be further configured to present an additional button labeled “Follow Me” (not shown), which, when selected by the user, configures the electro-
anatomic mapping system 34 for “follow me” control. This style of control is not currently available using a conventional keyboard and mouse interface. For “follow me” control, UI logic 64 is configured to receive a rotation input from the user via the touch panel (e.g., joystick 78); however, the received input is interpreted bysystem 34 as a request to rotate the endocardial surface rendering (the “map”) while maintaining the mapping catheter still or stationary on the display. In an embodiment, the physician can set the position and orientation of the mapping catheter, where it will remain stationary after the “Follow Me” button is selected. - Another feature of the
touch panel computer 26 a is that it incorporates, in an embodiment, voice recognition technology. As described above,computer 26 a includesmicrophone 66 for capturing speech (audio) andvoice recognition logic 68 for analyzing the captured speech to extract or identify spoken commands. The voice recognition feature can be used in combination with the touch panel functionality ofcomputer 26 a. Themicrophone 66 may comprise conventional apparatus known in the art, and can be a voice recognition optimized microphone particularly adapted for use in speech recognition applications (e.g., an echo-cancelling microphone).Voice recognition logic 68 may comprise conventional apparatus known in the art. In an embodiment,voice recognition logic 68 may be a commercially available component, such as software available under the trade designation DRAGON DICTATION™ speech recognition software. - In an embodiment,
computer 26 a is configured to recognize a defined set of words or phrases adapted to control various functions of the multiple applications that are accessible or controllable bycomputer 26 a. The voice recognition feature can itself be configured to recognize unique words or phrases to selectively enable or disable the voice recognition feature. Alternatively (or in addition to), a button, such asbutton 80 inFIG. 3A , can be used to enable or disable the voice recognition feature. In this regard, the enable/disable button can be either a touch-sensitive button (i.e., screen object), or can be hardware button. -
Voice recognition logic 68 is configured to interact with the physician or other user to “train” the logic (e.g., having the user speak known words) so as to improve word and/or phrase recognition. The particulars for each user so trained can be stored in a respective voice (user) profile, stored inmemory 62. For example, inFIG. 3A , the currently active voice profile is listed in dashed-line box 89. In an embodiment, each user can have unique commands, which may also be stored in the respective voice profile. In a further embodiment, the language need not be English, and can be other languages. This flexibility as to language choice enlarges the audience of users who can use thedevice 26 a. The voice recognition feature presents a number of advantages, including the fact that thephysician 16 does not have to remove his/her hands from the catheter or other medical device being manipulated. In addition, the absence of contact or need to touchcomputer 26 a maintains a sterile condition. The voice recognition feature can also be used either alone or in combination with other technologies. - With continued reference to
FIG. 3A , UI logic 64 also presents a “Settings”button 82. When the “Settings”button 82 is selected, UI logic 64 generates another screen display that allows the user to adjust and/or set/reset various settings associated with the application currently selected. In an embodiment, the “Settings” button can also allow adjustment of parameters that are more global in nature (i.e., apply to more than one application). For example only, through “Settings”, the physician or another user can edit all of the phrases associated with a particular physician or specify a timeout (i.e., the elapsed amount of time, after which the computer will stop listening (or not) for voice commands). The physician or another user can also edit miscellaneous parameters, such as communication settings and the like. -
FIG. 3B is an isometric view of asterile drape 88 configured to protect thetouch panel computer 26 a ofFIG. 3A from contamination and to maintain the physician's sterility. Conventional materials and construction techniques can be used to makedrape 88. -
FIG. 5 is a plan view oftouch panel computer 26 a showing a different application-specific user interface, now relating to EP monitoring and recording system 38 (i.e., “EP-WorkMate”). In the illustrative embodiment, UI logic 64 produces the same application-selection group 70 of buttons along the top of the touch panel, for quick and easy movement by the user between applications. A second, common-tasks group of buttons, designated asgroup 90, are shown belowgroup 70. For example, the three buttons labeled “Record”, “Update”, and “Add Map Point” can execute the identified function. Likewise, additional groups of buttons are shown, grouped by function, for example the signals-adjustment group 92, theevents group 94, thetimer group 96 and theprint group 98. It should be understood that variations are possible, depending on the items that can be adjusted or controlled on the destination system. It warrants emphasizing that UI logic 64 thus presents a unique user interface tailored to the requirements of the particular application selected. Each group includes items that are commonly asked for by the physician. For example, in thesignals group 92, the Speed +/− buttons can be used to change the viewed waveform sweep speed as the physician may need more or less detail; the Page +/− buttons can be used to change the page of signals being viewed (e.g., from surface ECG signals to intracardiac signals); and the Amplitude +/− buttons can be used to change the signal amplitudes up or down. As a further example, in theEvents group 94, the enumerated Events buttons cause a mark to be created in the patient charting log to indicate a noteworthy (i.e., important) item or event, such as the patient was just defibrillated or entered a tachy-arrhythmia. Note that these items are all user definable and speakable (capable of being tied to the voice recognition function). The physician also needs to keep track of certain periods of time. Thus, in theTimer group 96, the timer buttons can be used to keep track of such periods of time, for example, such as a certain time after an ablation (e.g., 30 minutes) to verify that the ablation procedure is still effective. Finally, regarding theprint group 98, various print buttons are provided so as to avoid requiring a physician to verbally indicate (e.g., by way of shouting out “print that document to the case” or the like) and to include such documents in a final report. -
FIG. 6 is a plan view oftouch panel computer 26 a showing in exemplary fashion a further, different application-specific user interface relating to the ultrasound imaging system 32 (“ViewMate”). As with the other application-specific user interfaces, the user interface presented inFIG. 6 repeats the common, application-selection group of buttons, designatedgroup 70. A further group of buttons and adjustment mechanisms are located ingroup 100. The controls (buttons, sliders) provided for this user interface completely eliminate the need to have a separate ultrasound keyboard to control the console. The user interface shown can be different, independent on the kind of machine being controlled, but at a minimum may typically provide a way to control the receive gain, the depth setting, the focus zone, the TGC (i.e., time gain compensation) curve, the monitoring mode (e.g., B, M, color Doppler, Doppler), image recording, as well as other image attributes and states. Note,trackpad object 101 is shown in the center of the user interface. The capability provided by UI logic 64 to rapidly switch applications and present to the bedside user an application-specific user interface minimizes or eliminates many of the shortcomings set forth in the Background. - It should be understood that variations in UI logic 64 are possible. For example, certain applications can be linked (in software) so that multiple applications can be controlled with a single command (e.g., the Record command). In another embodiment, UI logic 64 can be configured to provide additional and/or substitute functions, such as, without limitation, (1) map creation; (2) collecting points; (3) segmenting regions by anatomy; (4) map view (rotate and zoom); (5) select/manipulate a number of maps and view each; (6) selection of signal trace display; (7) adjust EP signal amplitude; (8) sweep speed; (9) provide single button (or touch, multi-touch, gesture) for recording a segment, placing an event marker, and/or placing a lesion marker.
- It should be further understood that the screen layouts in the illustrative embodiment are exemplary only and not limiting in nature. The UI logic 64 can thus implement alternative screen layouts for interaction by the user. For example, while the screen displays in
FIGS. 3A, 5 and 6 show an approach that incorporates the top level menu items on every screen, multi-level menus can also be used. For example, the screen layouts can be arranged such that a user descends down a series of screens to further levels of control. To return to upper levels (and to the “home” screen), a “Back” button or the like can be provided. Alternatively, a “Home” button can be provided. - In a still further embodiment, UI logic 64 can be configured for bi-directional display of information, for example, on the touch-responsive display panel. As one example, the “EnSite” user interface (
FIG. 3A ) can be configured so that the EnSite™ model is sent to thecomputer 26 a and displayed on the touch-responsive display panel. The user interface provided by UI logic 64 can allow the user to drag his or her finger on the panel to rotate the model. The display of the model provides context with respect to the act of dragging. Other information can be displayed as well, such as a waveform. In various embodiments, all or a portion of the items/windows displayed on monitor 20 (see, e.g.,FIGS. 2, 4A, and 4B ) may be displayed or mirrored on the touch-responsive display panel. For example, display area orwindow 52 may be displayed on the touch-responsive display panel allowing the physician or other user to directly modify the features ofwindow 52 at the patient's bedside. Other display areas/windows, such aswindows FIG. 2 ) may also be displayed and/or modified on the touch-panel display panel. One further example involves displaying feedback information or messages originating from the various devices or systems back to the touch-responsive display panel. In this regard, the UI logic 64 can configure any of the user-interfaces to have a message area, which can show informational messages, warning messages or critical error messages for viewing by the user. The message area feature provides a way to immediately alert the physician to such messages, rather than the physician having to watch for messages on multiple displays. -
FIG. 7A is a diagrammatic and block diagram view of a second embodiment of the bedside interface device, comprising anelectronic wand system 26 b. As withtouch panel computer 26 a,wand system 26 b is configured to allow the EP physician to take control, bedside of the patient, of an EP diagnostic or therapeutic system, such as the electro-anatomic mapping system 34. Thewand system 26 b includes a wirelessremote control portion 102, anoptical emitter portion 104, and abase interface 28 b, which may be coupled to the desired, target EP system through either a wired or wireless connection. Thewand system 26 b incorporates remote control technology, and includes the ability to detect and interpret motion of the remote control indicative of an EP physician's command or other instruction, detect and interpret key-presses on the remote control, and/or detect and interpret motion/keypress combinations. - Since the
wand system 26 b is contemplated as being used in the sterile procedure room, multiple embodiments are contemplated for avoiding contamination. In this regard,wand system 26 b may be configured with a disposableremote control portion 102, with a reusableremote control portion 102 that is contained within an enclosure compatible with sterilization procedures, with a reusableremote control portion 102 adapted to be secured in a sterilization-compatible wrapper, or with a reusableremote control portion 102 that is encased in a sterile but disposable wrapper. - With continued reference to
FIG. 7A ,remote control portion 102 may include anoptical detector 106, anelectronic processor 108, amemory 110, anoptional accelerometer 112 and a wireless transmitter/receiver 114. Theprocessor 108 is configured to execute a control program that is stored inmemory 110, to achieve the functions described below. Theoptical emitter 104 is configured to emit alight pattern 105 that can be detected and recognized byoptical detector 106. For example, the light pattern may be a pair of light sources spaced apart by a predetermined, known distance. The control program in remote 102 can be configured to assess movement of thelight pattern 105 as detected by detector 106 (e.g., by assessing a time-based sequence of images captured by detector 106). For example, in the exemplary light pattern described above,processor 108 can be configured to determine the locations of the light sources (in pixel space). In an embodiment, the control program in remote 102 may only discern thelight pattern 105 itself (e.g., the locations in pixel space) and transmit this information tobase interface 28 b, which in turn assesses the movement of the detected light pattern in order to arrive at a description of the motion of the remote 102. In a still further embodiment, various aspects of the processing may be divided betweenprocessor 108 and a processor (not shown) contained inbase interface 28 b. Theprocessor 106 communicates withbase interface 28 b via the wireless transmitter/receiver 114, which may be any type of wireless communication method now known or hereafter developed (e.g., such as those technologies or standards branded Bluetooth™, Wi-Fi™, etc.). Theprocessor 108 is configured to transmit wirelessly to interface 28 b the detected keypresses and information concerning the motion of the remote control 102 (e.g., the information about or derived from the images from the optical detector 106). In an embodiment, the motion ofremote control 102 may also be determined, or supplemented by, readings from accelerometer 112 (which may be single-axis or multi-axis, such as a 3-axis accelerometer). In some instances, rapid motion may be better detected using an accelerometer than using optical methods. In an embodiment,electronic wand system 26 b may be similar to (but differing in application, as described herein) a commercially available game controller sold under the trade designation Wii Remote Controller, from Nintendo of America, Inc. - Either the remote 102 or the
base interface 28 b (or both, potentially in some division of computing labor) is configured to identify a command applicable to the one of the EP diagnostic/therapeutic systems, such as electro-anatomic mapping system 34, based on the detected motion of the remote 102. Alternatively, the command may be identified based on a key press, or a predetermined motion/key press combination. Once the remote 102 and/orinterface 28 b identifies the command it is transmitted to the appropriate EP system. In an electro-anatomic mapping system embodiment, the wirelessremote control 102 is configured to allow an EP physician to issues a wide variety of commands, for example only, any of the commands (e.g., 3D model rotation, manipulation, etc.) described above in connection withtouch panel computer 26 a. By encoding at least some of the control through the wirelessremote control 102 that the EP physician controls, one or more of the shortcomings of conventional EP labs, as described in the Background, can be minimized or eliminated. As withtouch panel computer 26 a,electronic wand system 26 b can reduce procedure times as the EP physician will spend less time playing “hot or cold” with the mapping system operator (i.e., the control technician), but instead can set the display to his/her needs throughout the medical procedure. -
FIG. 7B shows a further embodiment, designatedinterface device 26 c.Interface device 26 integrates theremote control 102 described above into the handle of acatheter 115. Through the foregoing, the physician need not take his hands off the catheter, but rather can issue direct, physical commands (e.g., via key-presses) while retaining control of the catheter. Additionally, one or more of the keys or a slider switch on the catheter handle may serve as a safety mechanism to prevent inadvertent activation of one or more commands while operating the catheter. In such an embodiment, after advancing the catheter into a patient's body, the safety mechanism may be deactivated or otherwise turned off such that the physician can issue commands and then he or she may reactivate or turn on the safety mechanism and resume manipulating the catheter without fear of modifying the view or model shown on an on-screen display, for example. Thecatheter 115 may further comprise one or more electrodes on a distal portion of the catheter shaft and a manual or motorized steering mechanism (not shown) to enable the distal portion of the catheter shaft to be steered in at least one direction. In at least one embodiment, the catheter handle may be generally symmetric on opposing sides and include identical or nearly identical sets of controls on opposing sides of the handle so that a physician need not worry about which side of the catheter handle contains the keys. In another embodiment, the catheter handle may be generally cylindrical in shape and include an annular and/or rotatable control feature for issuing at least one command, again so the physician need not worry about the catheter handle's orientation in his or her hand(s). Exemplary catheters, handles, and steering mechanisms are shown and described in U.S. Pat. No. 5,861,024, U.S. application Ser. No. 12/861,555, filed 23 Aug. 2012 (the '555 application), U.S. Pat. Nos. 7,465,288, and 6,671,533, each of which is hereby incorporated by reference as though fully set forth herein. -
FIG. 8 is a diagrammatic and block diagram view of a fourth embodiment of the bedside interface device, comprising amotion capture apparatus 26 d. As withtouch panel computer 26 a,wand system 26 b andintegrated system 26 c,motion capture apparatus 26 d is configured to allow the EP physician to take control, bedside of the patient, of an EP diagnostic or therapeutic system, such as electro-anatomical mapping system 34. Themotion capture apparatus 26 d includes acapture apparatus 116 having both anoptical sub-system 118 and amicrophone sub-system 120 where theapparatus 116 is coupled to abase interface 28 b. Theapparatus 116 is configured to optically detect the motion or physical gestures of the EP physician or other user when such movements occur within asensing volume 122. Thebase interface 28 b may be coupled to the desired, target EP system through either a wired or wireless connection. - The
motion capture apparatus 26 d includes the capability to detect hand/arm/leg/trunk/facial motions (e.g., gestures) of the EP physician or other user and translate the detected patterns into a desired command.Apparatus 26 d also includes audio capture and processing capability and thus also has the capability to detect speech and translate the same into desired commands. In an embodiment,apparatus 26 d is configured to detect and interpret combinations and sequences of gestures and speech into desired commands. Thebase interface 28 b is configured to communicate the commands (e.g., rotation, zoom, pan of a 3D anatomical model) to the appropriate EP diagnostic or therapeutic system (e.g., the electro-anatomic mapping system 34). In an embodiment, themotion capture apparatus 26 d may comprise commercially available components, for example, the Kinect™ game control system, available from Microsoft, Redmond, Wash., USA. A so-called Kinect™ software development kit (SDK) is available, which includes drivers, rich application programming interfaces (API's), among other things contents, that enables access to the capabilities of the Kinect™ device. In particular, the SDK allows access to raw sensor streams (e.g., depth sensor, color camera sensor, and four-element microphone array), skeletal tracking, advanced audio (i.e., integration with Windows speech recognition) as well as other features. - Since there is no contact contemplated by
EP physician 16 during use ofmotion capture apparatus 26 d, contamination and subsequent sterilization issues are eliminated or reduced. In addition, the lack of contact withapparatus 26 d for control purposes allows the EP physician to keep his hands on the catheter or other medical device(s) being manipulated during an EP procedure. By encoding at least some of the control through themotion capture apparatus 26 d, with which the EP physician interacts, one or more of the shortcomings of conventional EP labs, as described in the Background, can be minimized or eliminated. As with the previous embodiments, themotion capture apparatus 26 d can reduce procedure times. - It should be understood that variations are possible. For example, the
motion capture apparatus 26 d can be used in concert with sensors and/or emitters in a sterile glove to assist theapparatus 26 d to discriminate commands intended to be directed to one of the EP systems, versus EP physician hand movements that result from his/her manipulation of the catheter or medical device, versus other movement in the EP lab in general. In another embodiment, themotion capture apparatus 26 d may discriminate such commands by being “activated” by a user when a specific verbal command is issued (e.g., “motion capture on”) and then “deactivated” by the user when another specific verbal command is issued (e.g., “motion capture off”). -
FIGS. 9-10 are diagrammatic views of fifth and sixth embodiments of the bedside interface device, comprising touch responsive devices.FIGS. 9 and 10 show touch-screenmouse pad devices EP physician 16 can move the mouse cursor from application to application and control each such application independently.Devices -
FIG. 11 is a diagrammatic view of a seventh embodiment of the bedside interface device comprising a customizedjoystick 26 g.Joystick 26 g can also be covered in a sterile bag. Thedevice 26 g can be used to be provide application-specific control a particular application function(s), such as rotating a 3D model (system 34), adding lesion markers, and the like. -
FIGS. 12-13 are diagrammatic views of eighth and ninth embodiments of the bedside interface device comprising holographic mouse and keyboard input devices, respectively.Holographic mouse 26 h deployslight beam pattern 124, which is used by themouse 26 h to acquire user input (i.e., movement of the physician's finger, instead of moving a conventional mouse). The movement input can be used in the same manner as that obtained from a conventional mouse.Holographic keyboard 26 i also deploys alight beam pattern 126 corresponding to a keyboard. A physician's finger can be used to “select” the key much in the same manner as a conventional keyboard, but without any physical contact.Devices - It should be understood that variations are possible. For example, in a further embodiment, primary control by the physician in manipulating or interacting with the mapping system may be through use of voice control alone (i.e., a microphone coupled with voice recognition logic), apart from its inclusion with other modes or devices for user interaction described above. In a still further embodiment, the physician can be equipped with headgear that monitors head movements to determine at what location on the screen/monitor the physician is looking. In effect, such headgear can act as a trackball to move or otherwise manipulate an image (or view of a model) on the monitor in accordance with the physician's head movements. In a yet further embodiment, the physician can be equipped with headgear that monitors head movements and/or also monitors brainwave patterns (e.g., to record a user electroencephalogram (EEG)). Such monitored data can be analyzed to derive or infer user input or commands for controlling an image (or view of a model), as described above. An EEG-based embodiment may comprise conventional apparatus known in the art, for example, commercially available products respectively sold under the trade designation MindWave™ headset from NeuroSky, Inc., San Jose, Calif., USA, or the Emotiv EPOC™ personal interface neuroheadset from Emotiv, Kwun Tong, Hong Kong. In a still further embodiment, the physician can be equipped with an eye tracking apparatus, wherein monitored eye movements constitute the user input to be interpreted by the system (e.g., the eye movements can be interpreted as a cursor movement or other command).
- It should also be appreciated that while the foregoing description pertains to an EP physician manually controlling a catheter through the use of a manually-actuated handle or the like, other configurations are possible, such as robotically-actuated embodiments. For example, a catheter movement controller (not shown) described above may be incorporated into a larger robotic catheter guidance and control system, for example, as seen by reference to U.S. application Ser. No. 12/751,843, filed 31 Mar. 2010, which is hereby incorporated by reference as though fully set forth herein. Such a robotic catheter system may be configured to manipulate and maneuver catheters within a lumen or a cavity of a human body, while the bedside interface devices described herein can be used to access and control the EP diagnostic and/or therapeutic systems. In at least one embodiment, a bedside interface device as described herein may also be used to access and control the robotic catheter system.

FIG. 14 is a block diagram of a base interface, designated 128, which may be one part of a system 127 (FIG. 15 ) configured to enable one or more users to remotely control a robotic medical device system, such as a robotic catheter system. In an embodiment, another part ofsystem 127 may comprise a motion capture apparatus, for example,motion capture apparatus 26 d shown inFIG. 15 .Motion capture apparatus 26 d may be configured to capture the motion of one or more users in a sensing volume and generate output data indicative of the captured user motion.Base interface 128 may be configured generally to analyze the generated output data from themotion capture apparatus 26 d to identify/recognize one or more three-dimensional (3D) gestures, and then translate such gestures into one or more robotic catheter control commands. The catheter control commands may be configured to control an aspect of the operation of the robotic catheter system. One such robotic catheter system is described in connection withFIGS. 18-23 . - With continued reference to
FIG. 14 ,base interface 128 includes an electronic control unit having one or moreelectronic processors 130 andmemory 132.Base interface 128 further includesgesture recognition logic 134 andinterpreter logic 136. Bothgesture recognition logic 134 andinterpreter logic 136, in an embodiment, comprise programmed logic (e.g., software) that is stored inmemory 132 and is configured to be executed by the one ormore processors 130. -
Gesture recognition logic 134 is configured to recognize one or more three-dimensional (3D) user gestures based on an analysis of the output data generated bymotion capture apparatus 26 d. In an embodiment,motion capture apparatus 26 d comprises commercially available components, for example, the Kinect™ game control system, available from Microsoft, Redmond, Wash., USA.Gesture recognition logic 134 can, in an embodiment, comprise implementations developed using a Kinect™ software development kit (SDK), which includes drivers, rich application programming interfaces (API's), among other things, that enables access to the capabilities of the Kinect™ device. The SDK allows access to raw sensor streams (e.g., depth sensor, color camera sensor, and four-element microphone array), skeletal tracking, advanced audio (i.e., integration with Windows speech recognition) as well as other features. -
Interpreter logic 136 is configured to translate the one or more 3D gestures recognized bygesture recognition logic 134 to one or more corresponding robotic catheter control commands. Such robotic catheter control commands may be configured to control one or more aspects of the operation of a robotic catheter system, such as the robotic catheter system described in connection withFIGS. 18-23 . For example only, such commands can include deflection, rotation, and/or translation of one or more robotically controlled catheters and/or sheaths.Interpreter logic 136, in an embodiment, may comprise application level code configured to use, for example, various features available in the Kinect™ SDK mentioned above. -
FIG. 15 is a diagrammatic and block diagram view ofsystem 127, which includesmotion capture apparatus 26 d andbase interface 128. In at least one embodiment,motion capture apparatus 26 d includescapture apparatus 116 having bothoptical sub-system 118 andmicrophone sub-system 120, as described above in connection withFIG. 8 .Motion capture apparatus 26 d may be configured to detect (e.g., optically) the physical motion of various objects, such as a user including portions of the user such as fingers, hands, arms, etc., that occur within asensing volume 122. The detected physical motion can also be that of a user-controlled implement, such as a wand (e.g., part or all ofelectronic wand system 26 b described above) or the like. In an embodiment,sensing volume 122 is located proximate to themotion capture apparatus 26 d.Motion capture apparatus 26 d may be electrically connected tobase interface 128 for communication thereto of user motion data. - The user motion data is indicative of the captured user motion. The user motion data may include imaging data as well as other information concerning the 3D posture of various objects in the sensing volume. In this regard, it should be appreciated that as updates occur over time, the resulting time-based series can be used to determine the motion patterns of the objects being tracked.
Base interface 128 may be coupled to a robotic catheter system such asrobotic control system 210, as shown, over acommunication mechanism 46, as also described above. - In an embodiment, gesture recognition logic 134 (
FIG. 14 ) is configured to track an object, for example, a specific body part such as a user's hand.Motion capture apparatus 26 d can define the tracked object by one or more fiducial points. For example, in an embodiment,motion capture apparatus 26 d, in combination with software functionality as implemented in base interface 128 (e.g., via the SDK), can recognize and track the time-based motion of a person's body orskeleton 138, including the time-based tracking of one or more of a plurality of constituent joints 140 1, 140 2, . . . 140 n, where n is an integer. The above-mentioned fiducial points may be taken to correspond to the joints 140 1, 140 2, . . . 140 n.Gesture recognition logic 134 can track the time-based positions of these fiducial points. The tracked positions in turn can form the basis of various metrics, such as position, distance, and rotation, all to be described below. - In light of the above, the output data generated by
motion capture apparatus 26 d includes fiducial point tracking data associated with a plurality of fiducial points defined with respect to the user. The fiducial point tracking data includes, for each fiducial point, a respective position. Each position may include a respective three-dimensional coordinate in a reference coordinate system, for example, defined withinsensing volume 122 that is monitored bymotion capture apparatus 26 d. In addition and/or in the alternative, the output motion data generated bymotion capture apparatus 26 d may comprise imaging data. - As shown in
FIG. 16A , for example, askeleton 138 a shows the respective positions of two fiducial points at 140 3 and 140 4 corresponding to the separated hands of the user.Gesture recognition logic 134 is configured to determine the position of the user's hands, and also adistance 142 between the user's hands. The position and distance between the user's hands can be translated byinterpreter logic 136 to a robotic catheter control command. For example, the position and distance between the user's hands can be used to control the degree of extension or retraction of a catheter and/or a sheath along a respective translation axis. Thus, more generally, a robotic catheter control command may have a characteristic that corresponds to the magnitude of the action that is to be initiated by the command. In the example ofFIG. 16A , the magnitude of the action may be defined by the distance between preselected fiducial points. The action may be a catheter extension, a catheter retraction, a sheath extension, and a sheath retraction. - As shown in
FIG. 16B , as a further example, askeleton 138 b shows a sequence of time-based positions traversed by a single fiducial point (joint 140 4) during the rotation of a user's wrist. The time-based positions of the tracked fiducial point (joint 140 4) at times t1, t2, t3, t4 and t5 are designated 140 4-1, 140 4-2, 140 4-3, 140 4-4, and 140 4-5 respectively. Through tracking,gesture recognition logic 134 can determine the extent of the rotation, as indicated byrotation angle 144. In an embodiment,gesture recognition logic 134 recognizes the rotational motion whileinterpreter logic 136 translates this gesture into an output command, for example only, to actuate rotation of a catheter and/or a sheath.Interpreter logic 136 can be configured to generate the output rotation command further as a function of the determined rotation angle 144 (i.e., the extent of actual catheter and/or sheath rotation can be made to correspond to the determined rotation angle 144). The fiducial point tracking data output frommotion capture apparatus 26 d therefore includes, for each fiducial point, a respective time-based plurality of positions. Thus, more generally, a robotic catheter control command may have a characteristic that corresponds to the rotation associated with the action to be initiated by the command. In the example ofFIG. 16B , the rotation may be defined by the rotation angle through which the preselected fiducial point rotates. The action may be a catheter or sheath rotation. - In an embodiment, in the case of a gesture involving wrist rotation,
gesture recognition logic 134 can be additionally configured to identify and track a wand (e.g., part or all ofelectronic wand system 26 b described above), a baton or a like implement being held in the hand of the user. The use of such implements can improve the ability of themotion capture apparatus 26 d to track the user's wrist motion (rotation). For example, a wand, being generally larger and more distinct than a wrist fiducial point (joint), can be expected to provide a correspondingly larger object in the imaging data and/or other data provided by themotion capture apparatus 26 d. This effectively provides greater resolution and robustness in the tracking functionality ofmotion capture apparatus 26 d/gesture recognition logic 134. -
Gesture recognition logic 134 may be configured to operate as described below to recognize a 3D gesture. First,gesture recognition logic 134 is configured to identify a start pose based on the fiducial point tracking data. In an embodiment, the start pose may correspond to a start condition where a first set of fiducial points assumes a first relationship therebetween. For example, this condition may be satisfied when the fiducial points form a first predetermined “constellation”. Second,gesture recognition logic 134 is configured to record the motion of a predetermined plurality of fiducial points after recognition of the start pose, and continue recording until an end pose is identified, which identification is also based on the fiducial tracking data. In an embodiment, the end pose may correspond to an end condition where a second set of fiducial points assume a second relationship therebetween. For example, this condition may be satisfied when the fiducial points form a second predetermined “constellation”. - Third,
gesture recognition logic 134 is configured to compare the recorded motion of the predetermined plurality of fiducial points (being tracked) with a plurality of predefined gestures. Each predefined gesture is itself defined by a respective motion of a respective set of fiducial points. Finally,gesture recognition logic 134 is configured to output one of the plurality of predefined gestures as the recognized gesture when the recorded motion matches one of the predefined gestures (i.e., the recognized gesture being the one that matches the recorded motion). -
System 127 may also include various safety features. As described above,motion capture apparatus 26 d is generally responsive to activity occurring withinsensing volume 122. In an embodiment,motion capture apparatus 26 d/gesture recognition logic 134 can be configured to be responsive only to activity in a smaller 3D volume included within sensing volume 122 (hereinafter an “action box”). The purpose of the action box is that once it is defined,system 127 will only respond to actions that occur within the action box. For example, a user can only actuate the robotic catheter system by placing his hands in the action box or otherwise causing some activity to occur in the action box. This arrangement can be expected to reduce the occurrence of unintended actuation, thereby improving safety. The action box ofsensing volume 122 can be positioned above a patient table (seeFIG. 2 , which shows a patient table and patient), in a control room, for example, control area/room 12 inFIG. 1 , or in various other locations. - In an embodiment,
system 127 can be configured to allow the user to adjust either or both of the size and location of the action box relative tomotion capture apparatus 26 d. It should be understood thatmotion capture apparatus 26 d will only respond to activities occurring within the action box, and ignore all other activity outside the action box. Staff can be trained to never place their hands or any other object into the action box as it is strictly for use by a trained physician because of the potential to actuate functionality of a medical device. In this regard, the action box can be delineated by a visible construct, such as a frame. The frame can be made of solid material, in which case is also presents a physical construct, or the outlines of the frame can be illuminated, for example, via low intensity laser beams. - For additional safety protection,
system 127 can be configured to include a user-actuatable switch such as a dead-man switch 146.Switch 146 may include a normally open state and a user-actuatable closed state.System 127 can be configured to be active only when the dead-man switch 146 has been closed by the user.System 127 may only respond to user actions (gestures) when theswitch 146 has been actuated. In a further embodiment,system 127 may be configured to at least disable communication of a robotic control command to the robotic catheter system unlessswitch 146 is in the closed state. The dead-man switch 146 may comprise a switch on a wand, a foot pedal, or the like. - Although an embodiment has been described in connection with
FIGS. 14-15 andFIGS. 16A-16B , other motion capture mechanisms can be used. For example, alternatives include an optical-based position tracking product (e.g., object or fiducial tracking system) known by the trade designation as the POLARIS® system and a magnetic-field based product known by the trade designation as the AURORA® system, both from Northern Digital Inc. -
FIG. 17 shows a further embodiment involving hand motion tracking where auser input device 1000 can include a spatially detected glove or stylus. In an embodiment whereuser input device 1000 includes a spatially detected glove, the user's/wearer's index finger can be instrumented with various sensors 1040 (e.g., position and orientation sensors, and/or accelerometers). The glove or stylus input device can be locatable in 3-D space through the use of a positioning system employing a magnetic field, an electrostatic field, or through the use of an optical positioning system. In an embodiment, the positioning system can be implemented within a liquid tank (e.g., water tank), where field generators, such as those associated with the EnSite™ NavX™ control system (a product of St. Jude Medical), are externally attached. For such embodiments, an instrumented glove or stylus can extend into the tank while, for example, the user's finger (e.g., index finger), or stylus can be instrumented with electrodes configured to measure parameters of the electric field. In an embodiment, the construction and/or placement of the sensors (e.g., EnSite™ NavX™-type electrodes) can be similar to sensors on the distal portion of the catheter. In another embodiment, the positioning system can be implemented using a magnetic positioning system. - In the illustrated embodiment of
FIG. 17 , amagnetic positioning system 1070 can operate, for example, by emitting several magnetic fields 1072 a-1074 c from an array of field generators 1074 a-1074 c. Sensor coils (e.g.,sensors 1040 or 1052) located on the glove or stylus can then sense the magnetic field strength emanating from each sensor coil. By selectively energizing each field generator at a different time or frequency, aprocessor 1080 can be able to resolve the sensor's position and orientation relative to each field generator or to a fixed reference sensor. Detected changes in the position and orientation of the glove or stylus sensor can then be registered and user motion data can be determined, and passed on togesture recognition logic 134. - In a still further embodiment, a haptic glove (not shown) with sensors can be provided in order to capture user motion, to thereby allow recognition of user gestures, as seen by reference to U.S. application Ser. No. 12/507,175, filed 22 Jul. 2009 (published as United States patent application publication no. US 2010/0073150 A1), and hereby incorporated by reference as though fully set forth herein. A haptic glove can output data that allows detection of the relative bending of the fingers and joints within the hand. Various motions of the hand can be indicators of desired motion to be input into the robotic catheter system. A haptic glove or similar devices have the potential to detect motion relative to itself, but not absolute motion relative to the physical (real) world. In an embodiment and referring again to
FIGS. 14-15 , a hybrid motion capture system is provided, wherein a haptic glove is configured to simultaneously provide relative motion such as finger bending as described above combined with an absolute location device, such asmotion capture apparatus 26 d, to form composite motions or gestures (using input from both systems). Such composite motions can be provided togesture recognition logic 134 andinterpreter logic 136 to output corresponding robotic catheter control commands, for effecting precise motions of the catheter and/or sheath of the robotic catheter system. - As described above, user-provided gestures can also be captured and used to control other electrophysiological systems, such an electro-anatomic mapping and visualization system (e.g., an EnSite™ Velocity™ system). In the scenario where user gesture capture is contemplated for controlling multiple, different systems, such as the robotic catheter system and the Ensite™ Velocity™ system,
system 127 can be configured with context switching functionality. In other words,system 127 is configured to determine when a gesture is intended to control one target system such as the robotic catheter system versus another target system such as an electro-anatomic mapping and visualization system. - To facilitate making such determinations,
system 127 is configured to analyze the actions occurring within acontext switching box 148, shown inFIG. 15 . As illustrated,context switching box 148 may be located near the corner ofsensing volume 122. In an embodiment,system 127 is configured to detect when the user is “tapping” incontext switching box 148. Thus, when the user “taps” a point incontext switching box 148,system 127 switches context (i.e., from the robotic catheter system as the target to the mapping system as the target) and thereafter allows user input to control an electro-anatomic mapping system target, such as the Ensite™ Velocity™ system. The act of tapping may involve the user holding his or her hand in a particular location and then ballistically moving the fingers back and forth. This tapping motion, when detected bygesture recognition logic 134, causes an electro-anatomic system, such assystem 34—FIG. 2 , to display a context menu visible to the user. For example, such a context menu may have a series of selectable options in a “drop-down” style box. - In operation, the user, by moving the hand up and/or down “over” the selectable options, causes the option over which the hand hovers to become highlighted.
Gesture recognition logic 134 can be further configured to recognize a second tapping motion, which finalizes the selection and closes the context menu. While the gesture itself can be captured usingsystem 127, other detection mechanisms, such as through the use of various sensors as described above (e.g., haptic glove, accelerometer disposed within a glove, a wand, etc.) can be alternatively used. - Thus, in light of the above,
system 127 may include context switching logic (not shown) stored inmemory 132 and configured for execution in the one ormore processors 130. The context switching logic may be configured to detect a predetermined context switching gesture (e.g., the “tapping” gesture described above) based on the output data frommotion capture apparatus 26 d, but only where the context switching gesture occurs in the context switching portion ofsensing volume 122. When the context switching logic detects the context switching gesture, it may set a context switch parameter or the like.Interpreter logic 136 is accordingly configured to selectively translate, based on the state of the context switch parameter, the recognized user gesture into one of either (i) a robotic catheter control command, or (ii) an electro-anatomic mapping system control command. - In another embodiment, further visual feedback can be displayed on the display of the electro-
anatomic system 34, such as on thedisplay area 52 inFIG. 2 , showing the relative motion of the user's hands and fingers. This feedback can be through the use of a (i) special-purpose mouse pointer in addition to and visibly distinguishable from a primary mouse pointer, (ii) a graphical representation of the hands, or the like. - Referring to
FIG. 15 , in another embodiment,system 127 can be used in combination with an electro-anatomic system 34 (FIG. 2 ) and further in combination with a three-dimensional (3D) display, such as that described in U.S. application No. 61/643,667, filed 7 May 2012, and hereby incorporated by reference as though fully set forth herein. This combination of functions allows for a virtual representation of the hands that could be rendered and displayed within a three-dimensional (3D) window along with representations of the catheters and/or sheaths, all with respect to a heart model. This 3D window may allow the user to perceive his or her own hands reaching into the heart of the patient. Through this facility, the user could “grab” the catheter and move it to a new location, for example, to a target location. For example, the virtual hands can be moved near the tip of one of the catheters, and by “pinching” on the tip of the catheter, the user can “grab and pull” the catheter in different directions. The target location can be specified as the location to which the rendered catheter is pulled by the user. Once the target location has been specified, this information can be passed on to therobotic control system 210 byinterpreter logic 136, whereinrobotic control system 210 processes this target location as a dynamic waypoint, and thereafter automatically move the catheter to such target location. The foregoing combination, including a 3D display, provides an intuitive way for a user to manipulate a medical device within the heart. - In another embodiment,
interpreter logic 136 can be configured to generate different commands based on the same user gesture.Interpreter logic 136 is configured to analyze the recognized use gesture in light of and as a function of the orientation of the then-visible (current) view of an anatomical model being displayed by an electro-anatomic system, such as system 34 (FIG. 2 ). In other words, the effect of the user gesture can be view relative, such that the same gesture can actuate different, relative motions based on the current view angle or orientation displayed by the electro-anatomic system 34. For example, the direction of translation can be different based on the current view, as shown in the examples in Table 1. -

- Referring to
FIG. 18 ,RCGS 210 can be likened to power steering for a catheter system. TheRCGS 210 can be used, for example, to manipulate the location and orientation of catheters and sheaths in a heart chamber or in another body cavity or lumen. TheRCGS 210 thus provides the user with a similar type of control provided by a conventional manually-operated system, but allows for repeatable, precise, and dynamic movements. For example, a user such as an electrophysiologist can identify locations (potentially forming a path) on a rendered computer model of the cardiac anatomy. The system can be configured to relate those digitally selected points to positions within a patient's actual/physical anatomy, and can thereafter command and control the movement of the catheter to the defined positions. Once at the specified target location, either the user or the system can perform the desired diagnostic or therapeutic function. TheRCGS 210 enables full robotic navigation/guidance and control. - As shown in
FIG. 18 , theRCGS 210 can generally include one or more monitors or displays 212, a visualization, mapping and navigation (including localization)system 214, a human input device and control system (referred to as “input control system”) 224, anelectronic control system 226, amanipulator assembly 300 for operating adevice cartridge 400, and amanipulator support structure 500 for positioning themanipulator assembly 300 in proximity to a patient or a patient's bed. -
Displays 212 are configured to visually present to a user information regarding patient anatomy, medical device location or the like, originating from a variety of different sources.Displays 212 can include (1) an EnSite™ Velocity™ monitor 216 (coupled tosystem 214—described more fully below) for displaying cardiac chamber geometries or models, displaying activation timing and voltage data to identify arrhythmias, and for facilitating guidance of catheter movement; (2) afluoroscopy monitor 218 for displaying a real-time x-ray image or for assisting a physician with catheter movement; (3) an intra-cardiac echo (ICE)display 220 to provide further imaging; and (4) an EPrecording system display 222. - The
system 214 is configured to provide many advanced features, such as visualization, mapping, navigation support and positioning (i.e., determine a position and orientation (P&O) of a sensor-equipped medical device, for example, a P&O of a distal tip portion of a catheter). Such functionality can be provided as part of a larger visualization, mapping and navigation system, for example, an EnSite™ Velocity™ system running a version of EnSite™ NavX™ software commercially available from St. Jude Medical, Inc., of St. Paul, Minn. and as described above.System 214 can thus comprise conventional apparatus, for example, the EnSite™ Velocity™ system, or other known technologies for locating/navigating a catheter in space (and for visualization), including for example, the CARTO visualization and location system of Biosense Webster, Inc., the AURORA® system of Northern Digital Inc., a magnetic field based localization system such as the MediGuide™ Technology, a system based on technology from MediGuide Ltd. of Haifa, Israel and now owned by St. Jude Medical, Inc., or a hybrid magnetic field-impedance based system, such as the CARTO 3 visualization and location system of Biosense Webster, Inc. Some of the localization, navigation and/or visualization systems can involve providing a sensor for producing signals indicative of catheter location and/or orientation information, and can include, for example one or more electrodes in the case of an impedance-based localization system such as the EnSite™ Velocity™ system running EnSite™ NavX™ software, which electrodes can already exist in some instances, or alternatively, one or more coils (i.e., wire windings) configured to detect one or more characteristics of a low-strength magnetic field, for example, in the case of a magnetic-field based localization system such as the MediGuide™ Technology, a system using technology from MediGuide Ltd. described above. - The
input control system 224 is configured to allow a user, such as an electrophysiologist, to interact with theRCGS 210, in order to control the movement and advancement/withdrawal of both a catheter and sheath (see, e.g., U.S. application Ser. No. 12/751,843, filed 31 Mar. 2010 (the '843 application), and PCT/US2009/038597, filed 27 Mar. 2009 (the '597 application), and published 1 Oct. 2009 under publication no. WO 2009/120982. The '843 application and the '597 application are both hereby incorporated by reference as though fully set forth herein. Generally, several types of input devices and related controls can be employed, including, without limitation, instrumented traditional catheter handle controls, oversized catheter models, instrumented user-wearable gloves, touch screen display monitors, 2-D input devices, 3-D input devices, spatially detected styluses, and traditional joysticks. For a further description of exemplary input apparatus and related controls, see, for example, U.S. application Ser. No. 12/933,063, filed 16 Sep. 2010 (the '063 application), and U.S. application Ser. No. 12/347,442, filed 31 Dec. 2008 (the '442 application). The '063 application and the '442 application are both hereby incorporated by reference as though fully set forth herein. The input devices can be configured to directly control the movement of the catheter and sheath, or can be configured, for example, to manipulate a target or cursor on an associated display. - The
electronic control system 226 is configured to translate (i.e., interpret) inputs (e.g., motions) of the user at an input device or from another source into a resulting movement of the catheter and/or surrounding sheath. In this regard, thesystem 226 includes a programmed electronic control unit (ECU) in communication with a memory or other computer readable media (memory) suitable for information storage. Relevant to the present disclosure, theelectronic control system 226 is configured, among other things, to issue commands (i.e., actuation control signals) to the manipulator assembly 300 (i.e., to the actuation units—electric motors) to move or bend the catheter and/or sheath to prescribed positions and/or in prescribed ways, all in accordance with the received user input and a predetermined operating strategy programmed into thesystem 226. In addition to the instant description, further details of a programmed electronic control system can be found in U.S. application Ser. No. 12/751,843, described above. It should be understood that although the exemplary EnSite™Velocity™ system 214 and theelectronic control system 226 are shown separately, integration of one or more computing functions can result in a system including an ECU on which can be run both (i) various control and diagnostic logic pertaining to theRCGS 210 and (ii) the visualization, mapping and navigation functionality ofsystem 214. - The
manipulator assembly 300, in response to such commands, is configured to maneuver the medical device (e.g., translation movement, such as advancement and withdrawal of the catheter and/or sheath), as well as to effectuate distal end (tip) deflection and/or rotation or virtual rotation. In an embodiment, themanipulator assembly 300 can include actuation mechanisms/units (e.g., a plurality of electric motor and lead screw combinations, or other electric motor configurations, as detailed below) for linearly actuating one or more control members (e.g., steering wires) associated with the medical device for achieving the above-described translation, deflection and/or rotation (or virtual rotation). In addition to the description set forth herein, further details of a manipulator assembly can be found in U.S. application Ser. No. 12/347,826, filed 31 Dec. 2008, which is hereby incorporated by reference as though fully set forth herein. Although themanipulator 300 is illustrated and described with respect to the manipulation of a single medical device (e.g., a single catheter and sheath combination), themanipulator 300 can be configured to manipulate multiple devices, such as a cardiac mapping catheter, an ablation catheter, an imaging catheter, such an intracardiac echocardiography (ICE) catheter, or the like, as seen by reference to international application no. PCT/US12/30697, with an international filing date of 27 Mar. 2012 (the '697 application), which claims priority to U.S. provisional application No. 61/581,838 filed 30 Dec. 2011 (the '838 application). The '697 application and the '838 application are both hereby incorporated by reference as though fully set forth herein. - A
device cartridge 400 is provided for each medical device controlled by theRCGS 210. For this exemplary description of an RCGS, one cartridge is associated with a catheter and a second cartridge is associated with an outer sheath. The cartridge is then coupled, generally speaking, to theRCGS 210 for subsequent robotically-controlled movement. In addition to the description set forth herein, further details of a device cartridge can be found in U.S. application Ser. No. 12/347,835, filed 31 Dec. 2008 (the '835 application), and U.S. application Ser. No. 12/347,842, filed 31 Dec. 2008 (the '842 application). The '835 application and the '842 application are both hereby incorporated by reference as though fully set forth herein. -
FIG. 19 is a side view of an exemplary robotic catheter manipulator support structure, designated structure 510 (see U.S. application Ser. No. 12/347,811, filed 31 Dec. 2008, hereby incorporated by reference as though fully set forth herein). Thestructure 510 can generally include asupport frame 512 includingretractable wheels 514 andattachment assembly 516 for attachment to an operating bed (not shown). A plurality ofsupport linkages 520 can be provided for accurately positioning one or more manipulator assemblies, such asmanipulator assembly 302. Theassembly 302 is configured to serve as the interface for the mechanical control of the movements or actions of one or more device cartridges, such as catheter andsheath cartridges assembly 302 also includes a plurality of manipulation bases onto which the device cartridges are mounted. After mounting, themanipulator assembly 302, through the manipulation bases, is capable of manipulating the attached catheter and sheath. - Referring to
FIG. 24 , themanipulator assembly 302 may include asupport device 382 positioned on the distal end of the manipulator assembly and configured to receive one or more ancillary tools, such as, for example, anintroducer 384, aguide 386, or a hemostasis pad 388. In an embodiment thesupport device 382 and ancillary tools, are configured to interact with a portion of the catheter and/or sheath between the manipulator and the patient. For example, as generally illustrated inFIG. 24 ,introducer 384 and/or guidetube 386 may direct the catheter into the patient at a fixed angle or position while allowing the manipulator to be oriented at a different relative angle. -
FIGS. 25A-25B are isometric and related diagrammatic views illustrating another embodiment of a manipulator support structure, designatedmanipulator support structure 650.Manipulator support structure 650 may generally include a track mountedunit 652 for movement ofmanipulator support structure 650 and its related components.Structure 650 may includeattachment assembly 654 for attachment to ceiling or otherwise mountedtrack 656, and a plurality ofsupport linkages 658 for accurately positioning roboticcatheter manipulator assembly 300. Referring toFIGS. 25A and 25B , in use,manipulator support structure 650 may be positioned relative tooperation bed 518 and locked in position during use, and moved out of the use position or otherwise re-configured to a stowed position by re-positioning ofsupport linkages 658. As shown inFIG. 25B , manipulator support structure may be moved generally horizontally and vertically for positioning and removal from the area ofoperation bed 518. - In the Figures to follow,
FIGS. 20A-20B will show a manipulator assembly,FIGS. 21A-21C will show a manipulation base, andFIGS. 22A-22B will show a device cartridge. -
FIG. 20A is an isometric view, with portions omitted for clarity, ofmanipulator assembly 302.Assembly 302 includes acatheter manipulator mechanism 304, asheath manipulator mechanism 306, acatheter manipulation base 308, asheath manipulation base 310, a first (catheter)drive mechanism 312, a second (sheath) drive mechanism 314, and atrack 356. As further shown,assembly 302 further includes acatheter cartridge 402 and asheath cartridge 404, with acatheter 406 having aproximal end opening 408 coupled to thecatheter cartridge 402 and asheath 410 coupled to thesheath cartridge 404. - Catheter and
sheath manipulator mechanisms catheter 406 and thesheath 410. First, eachmechanism catheter 406 and thesheath 410. Translation movement here refers to the independent advancement and retraction (withdrawal) as shown generally in the directions designated D1 and D2 inFIG. 20A . Second, eachmechanism sheath mechanism catheter 406 and thesheath 410. Virtual rotation can be made through the use of independent four-wire steering control for each device (e.g., eight total steering wires, comprising four sheath control wires and four catheter control wires). The distal end movement is referred to as “virtual” rotation because the outer surface of the sheath (or catheter) does not in fact rotate in the conventional sense (i.e., about a longitudinal axis) but rather achieves the same movements as conventional uni-planar deflection coupled with axial rotation. In addition to the present description of virtual rotation, further details can be found in international application no. PCT/US2009/038597, published 1 Oct. 2009, as WO 2009/120982, which is hereby incorporated by reference as though fully set forth herein. - Each
manipulator mechanism respective manipulation base sheath cartridges base track 356. In an embodiment, D1 and D2 can each represent a translation of approximately 8 linear inches. Each interlockingbase precision drive mechanism 312, 314. Such drive mechanisms can include, for example and without limitation, an electric motor driven lead screw or ball screw. - The
manipulator mechanisms catheter 406 can pass throughsheath 410 in a coaxial arrangement. Thus,sheath 410 can include a water-tightproximal sheath opening 408. Overall, themanipulator mechanisms sheath cartridges 402, 404 (and thus relative movement between catheter and sheath). -
FIG. 20B is an isometric view ofmanipulator assembly 302, substantially the same asFIG. 20B except that catheter andsheath cartridges sheath 406, 410) so as to reveal an exposed face of the manipulation bases 308, 310. -
FIG. 21A is an isometric, enlarged view showing manipulation base 308 (and base 310) in greater detail. Eachcartridge manipulation base base fingers FIG. 22B , to independently tensionselect steering wires FIG. 22B . Each finger can be configured to be independently actuated (i.e., moved back and forth within the oval slots depicted inFIG. 21A ) by a respective precision drive mechanism, such as a motor drivenball screw 324. Aplate 326 provides a surface onto which one of thecartridges -
FIG. 21B is an isometric, enlarged view of base 308 (and base 310), substantially the same asFIG. 21A except withplate 326 omitted. Each motor-drivenball screw 324, best shown inFIG. 21A , for both finger control and for cartridge translation control, can further include encoders to measure a relative and/or an absolute position of each element of the system. Moreover, each motor-drivenball screw 324, for both finger control and cartridge translation control, can be outfitted with steering wire force sensors to measure a corresponding steering wire tension. For example, acorresponding finger ball screw 324 can include a number of components, for example only, a rotary electric motor (e.g.,motors lead screw 328, abearing 330 and acoupler 332 mounted relative to and engaging aframe 340. In the depicted embodiments linear actuation is primarily, if not exclusively, employed. However, some known examples of systems with rotary-based device drivers include U.S. application Ser. No. 12/150,110, filed 23 Apr. 2008 (the '110 application); and U.S. application Ser. No. 12/032,639, filed 15 Feb. 2008 (the '639 application). The '110 application and the '639 application are hereby incorporated by reference in their entirety as though fully set forth herein. These and other types of remote actuation can directly benefit from the teaching of the instant disclosure. -
FIG. 21C is an isometric, enlarged view of base 308 (and base 310) that is taken from an opposite side as compared toFIGS. 21A-21B .Bases motors fingers bases track 356. A plurality of inductive sensors (e.g. home sensors) 358 can also be provided for guiding each manipulation base to a home position. -
FIG. 22A is an isometric, enlarged view showing, in greater detail,sheath cartridge 404. It should be understood that the description ofsheath cartridge 404, except as otherwise stated, applies equally tocatheter cartridge 402.Catheter 406 andsheath 410 can be substantially connected or affixed torespective cartridges 402, 404 (e.g., in the neck portion). Thus, advancement ofcartridge 404 correspondingly advances thesheath 410 and retraction ofcartridge 404 retracts thesheath 410. Likewise, although not shown, advancement ofcartridge 402 correspondingly advancescatheter 406 while a retraction ofcartridge 402 retractscatheter 406. As shown,sheath cartridge 404 includes upper andlower cartridge sections -
FIG. 22B is an isometric, enlarged view showing, in greater detail,sheath cartridge 404, withupper section 428 omitted to reveal interior components.Cartridge 404 can include slider blocks (e.g., as shown forcartridge 404, slider blocks 412, 414, 416, 418), each rigidly and independently coupled to a respective one of a plurality of steering wires (e.g.,sheath steering wires cartridge 402 forcatheter 406 also includes slider blocks for coupling to a plurality (e.g., four) steering wires.Device cartridges respective base Sheath cartridge 404 can be designed in a similar manner as thecatheter cartridge 402, but will typically be configured to provide for the passage ofcatheter 406. - Referring to
FIGS. 21A and 22A , catheter andsheath cartridges respective manipulation bases FIG. 22A ) on the cartridge can engage one or more mating recesses 360 in the base (seeFIG. 21A ). In an embodiment,such recesses 360 can include an interference lock such as a spring detent or other locking means. In an embodiment, such other locking means can include a physical interference that can require affirmative/positive action by the user to release the cartridge. Such action can include or require actuation of arelease lever 362. Additionally, the cartridge can include one or more locator pins (not shown) configured to passively fit into mating holes on the base (e.g., 364 inFIG. 21A ). - In operation, a user first manually positions
catheter 406 and sheath 410 (withcatheter 406 inserted in sheath 410) within the vasculature of a patient. Once the medical devices are roughly positioned in relation to the heart or other anatomical site of interest, the user can then engage or connect (e.g., “snap-in”) the catheter and sheath cartridges into place onrespective bases sheath cartridge 404 andsheath base 310, each of the plurality offingers FIG. 22B ). Each finger can be designed to be actuated in a proximal direction to respectively move each slider block, thereby placing the respective steering wire in tension (i.e., a “pull” wire). Translation, distal end bending and virtual rotation can be accomplished through the use of theRCGS 210. -
FIG. 23 is a diagrammatic view of a node suitable for connection to a communications bus (not shown) inRCGS 210. The node includes anactuation unit 600, similar to the actuation mechanisms described above (e.g., catheter actuation mechanism 304). In an embodiment, theRCGS 210 can have at least ten such actuation units (i.e., one for each of the four catheter steering wires, four sheath steering wires, one catheter manipulation base and one sheath manipulation base), which as described include electric motors. Of course, as described above, when theRCGS 210 is configured to manipulate multiple medical devices, each medical device will include a respective actuation assembly, suited to the type of medical device. -
FIG. 23 shows in diagrammatic or block form many of the components described above—where appropriate, references to the earlier describe components will be made.Actuation unit 600 includes a first, slidable control member 602 (e.g., the slider as described above) that is connected to or coupled with a second, tensile control member 604 (e.g., the steering wire as described above). Theslider 602 can be configured to interface with a third, movable control member 606 (e.g., the finger as described above). Thefinger 606 can further be operatively coupled with a portion of a sensor 608 (e.g., a force sensor), which, in turn, can be coupled with atranslatable drive element 610 that can be mechanically moved. For example, without limitation,translatable drive element 610 can ride on or can otherwise be mechanically moved by amechanical movement device 612 that, in turn, can be coupled with anelectric motor 614. Themechanical movement device 612 can comprise a lead screw while thetranslatable drive element 610 can comprise a threaded nut, which can be controllably translated byscrew 612 in the X+ or X− directions. In another embodiment,mechanical movement device 612 can include a ball screw, whiletranslatable drive element 610 can include a ball assembly. Many variations are possible, as will be appreciated by one of ordinary skill in the art. - The
actuation unit 600 also includes a rotarymotor position encoder 616 that is coupled to themotor 614 and is configured to output a signal indicative of the position of themotor 614. Theencoder 616 can comprise an internal, optical encoder assembly, integral withmotor 614, configured to produce a relatively high accuracy output. The motor position sensor can operate in either absolute or relative coordinates. In an embodiment, a second motor position sensor (not shown) can also be provided, such as a potentiometer (or impedance-based), configured to provide a varying voltage output proportional to the motor's rotary position. The output of the secondary position sensor can be used as an integrity check of the operating performance of the primary position sensor (encoder) during start-up or initialization of the actuation unit. -
Actuation unit 600 also includes one or more local controllers including abus interface 618 to facilitate exchange of information betweenactuation unit 600 and electronic control system 226 (via the bus). The controller communicates with the mainelectronic control system 226 via the bus interface and is configured, among other things, to (1) receive and execute motor actuation commands issued by theelectronic control system 226 for controlling the movements ofmotor 614; and (2) receive and execute a command (issued by the electronic control system 226) to take a motor position sensor reading, for example, fromencoder 616 and subsequently report the reading tosystem 226. - A user interface device in the form of a touch screen monitor will now be discussed with reference to
FIGS. 26A-26D . - An embodiment of user interface device may include a
multi-touch display interface 1100 and related hardware and software that would allow a user to physically interact with the robotic catheter system without the need for a keyboard, mouse, or other input device. Such a display may be configured to recognize multiple finger or hand contacts with or along the screen, and would allow a user to directly interface with the objects, anatomy, or devices displayed on the screen. - As shown in
FIGS. 26A-26B , an embodiment of themulti-touch interface 1100 may include multiple on-screen menu buttons 1102 that allow a user to toggle between various active functions within the image. Such functions may include, for example, the ability to pan, rotate, or zoom 3D objects and models within the display, select and/or direct movement of the catheter or sheath, place lesion markers, way points, virtual sensors, or automated movement targets and lines within the anatomic model. - In an exemplary approach, when in rotate mode, a user may rotate a
3D cardiac geometry 1104 by touching the screen with a finger and dragging across the screen to spin the 3D model about an axis orthogonal to both the surface normal of the screen and the direction of the dragging motion. When in pan mode, a dragging motion across the screen may physically move the model across the screen. Additionally, the zoom may be controlled, for example, through a pinching (zoom out) or expanding motion (zoom in) of multiple fingers, or through the use of an on-screen slider - As shown in
FIG. 26B , in an embodiment, themulti-touch interface 1100 may be used to control the movement of a displayedcatheter 1110 orsheath 1112 by first pressing on the image of the catheter or sheath to select it, followed by dragging the selected device in the direction of intended travel. Alternatively, thecatheter 1110 orsheath 1112 may be selected by using a pinching motion as if the user is virtually grabbing the image. In an embodiment, while the user is dragging a virtual representation of the catheter or sheath, aghost image 1114 of the current position of the device may be displayed as a reference. Theghost image 1114 may be based on real-time feedback of the actual catheter position as provided by a catheter positioning system such as Ensite NavX. Once the user is satisfied with the movement, the user may release the selected catheter or sheath by removing his/her finger from the screen. The system may then be configured to move the actual catheter in accordance with the user intended motion, and may update theghost image 1114 to reflect the actual movement. In another embodiment, the user may move a control point on the catheter or sheath and the actual catheter may be configured to track this point in real-time. - In an embodiment, as generally illustrated in
FIGS. 26A, 26C , the user may use themulti-touch interface 1100 to selecttarget points 1120 within the image. These target points may be used to identify lesion points for intended or completed therapy delivery, way-points for semi-automated step-wise catheter movement, destination points for fully automated movement, or as relative markers or virtual electrophysiology sensors that may have no impact on relative movement. In an embodiment, a target point may 1120 be initially set by taping on screen in a position where a target point is desired. Once a point has been set, it may be subsequently selected by re-tapping on the point. When a point is “selected,” it may change appearance, such as selectedpoint 1122. If the user desires to move target point, the user may for example, select it by tapping it, and then drag the point to a new location. Additionally, after selecting a point, the software may call up a list of menu options that may allow the user to configure or view one or more parameters of the point. Such parameters may include, for example, the nature of the point (e.g. marker, lesion point, waypoint, sensor) the distance of the point above the surface, or specific data recorded or computed at the point. - Once a user taps the screen in the desired location of the target point, the software may be configured to place the
target point 1120 directly on the surface of themodel 1104 as displayed. In such a configuration, the system may know the relative depth of each pixel or primitive on the display. By touching on a displayed element, the system may map the target point directly to the anatomical surface. The software may further allow the user to specify a fixed or minimum distance from the displayed anatomical surface where the point should be located. For example, if the user specifies a distance of 10 mm prior to selecting a point, the software may locate thetarget point 10 mm off of the selected surface in a direction normal to the screen/viewing plane. Alternatively, the software may generate a virtual surface located 10 mm interior to the surface of the anatomical model and then map the point to the virtual surface. (i.e. 10 mm normal to the anatomical model surface). In another embodiment, as shown inFIG. 26C , the user may select apoint 1122 with onefinger 1124, and use asecond finger 1126 to control avariable slider 1128 to specify a distance above the surface. Theslider 1128 may likewise be located on the side of the screen and/or may appear only after a point has been selected. The display may also be configured to display a secondary projection of the catheter and model to aid the user in positioning the target point in three dimensional space (e.g. using a right anterior oblique (RAO) projection as the primary display, and a left anterior oblique (LAO) projection as the secondary display). - Referring back to
FIG. 26B , in an embodiment, as the user is dragging a display of the catheter 1110 (or sheath 1112), the user may use a second finger to modulate a slider (such as a slider generally illustrated inFIG. 26C ) to control the catheter's distance from the anatomical surface in real time. Using this technique, the user could achieve a motion where, for example, the catheter begins in contact with the tissue, gradually lifts off from the tissue while traversing a distance, and gradually lands back on the tissue. Alternatively, for either free catheter motion, or for positioning a target point, the user may use a physical slider or wheel, apart from the display, to modulate the distance from the surface. Using the touch screen, the user may also control the extension of the catheter from the sheath by placing one finger on thecatheter 1112 and a second finger on thesheath 1114 and expanding or squeezing his/her fingers together. - In addition to setting individual target points, as illustrated in
FIG. 26A , the user may also be able to specify a line orpath 1130 along the surface of themodel 1104 by touching and dragging a finger across the screen. Such generatedline 1130 may be similar to a splined series of waypoints. Furthermore, in an embodiment, the user may select a point along the line and “lift” that point away from the surface by, for example, using a slider or numerical input. Points adjacent to the selected point may additionally be lifted off as if they were tied to the selected point. - In an embodiment, as shown in
FIG. 26D , themulti-touch interface 1100 may be used to manage multiple displays (such as displays A-D) in an integrated electrophysiology environment. Using the interface for display management purposes may include the ability to resize, move, minimize, or maximize windows that display, for example, EnSite NavX models, digital fluoroscopic displays, patient vital information, patient hospital records, real time electrocardiograph traces, CT imagery, MRI imagery, and/or any other displays desired by the user. In an embodiment, a user may move or expand a window using on-screen buttons to, for example, freeze the touch screen input for the respective displays, followed by touching and dragging the window to move it, or using a multi-finger expanding motion to, for example, expand the window. - In accordance with another embodiment, an article of manufacture includes a computer storage medium having a computer program encoded thereon, where the computer program includes code for acquiring or capturing motion of a user and generating corresponding output data, for recognizing a user gesture based on the user motion output data, and for translating the recognized user gesture into one or more commands for an EP diagnostic and/or therapeutic system, including at least a robotic catheter control command, or an electro-anatomic system command. Such embodiments may be configured to execute one or more processors, multiple processors that are integrated into a single system or are distributed over and connected together through a communications network, and where the network may be wired or wireless.
- It should be understood that while the foregoing description describes various embodiments of a bedside interface device in the context of the practice of electrophysiology, and specifically catheterization, the teachings are not so limited and can be applied to other clinical settings.
