- FIG. 9A shows a fourth alternative embodiment
- Catheter 130 is similar to catheter 70 shown in FIG. 5A and FIG. 5B, except that. a plurality of ports 132 are disposed proximate a second side of flexible body 131, rather than one port 78, as shown in FIG. 5A. With a plurality of ports, it is possible, for example, to use a therapeutic tool through one port while simultaneously suctioning and removing debris through another port; or a therapeutic tool can be used through one port while simultaneously electrophysiologically monitoring, suctioning and/or biopsying through a second port, third or fourth port.
- the use of the catheter of the present invention is described with respect to the preferred embodiment 20. It is understood that the use of alternative embodiments 70, 88, 110, 126 and 130 is analogous.
- the user would insert flexible catheter body 22 into the body via the appropriate vascular access to the desired location in the body, such as selected venous locations, heart chamber, etc.
- a guide wire might be first inserted into place and then the catheter body fed along the guide wire.
- the user might then insert a surgical device into the body through access port 40 and feed the surgical device to proximate distal end 26 of catheter body 22.
- the user Prior to, during and after operation of the surgical device, the user might obtain both hemodynamic measurements and images from the ultrasonic transducer field of view. By operation of the surgical device within the field of view of transducer 40, the user can monitor operation of the surgical device at all times.
- the proposed device optimally uses a 5 to 20 mHz transducer with the most optimally applied frequency of 7 to 10 mHz.
- the lower frequency used in the UIHC reflects the need to image larger objects such as the cardiac septa, valves, and extravascular anatomy.
- Intervention One primary function of this catheter system is to guide the logical and safe use of various a) ablation, b) laser, c) cutting, d) occluding, e) etc., catheter-based interventional cardiovascular tools. The invention has the access port through which other technologies (devices) can be passed. Once the interventional tool exits the catheter tip, it can be directed repeatedly and selectively to specific site for controlled intervention.
- D. Imaging The invention is also an imaging system capable of visualizing intracardiac, intravascular, and extravascular structures. Because the transducer frequencies utilized are usually lower than intravascular systems, the catheter 20 can see multiple cardiac cavities and visualize structures outside the vascular system. The imaging capability is basically two-fold: 1) diagnostic and 2) application.
- Diagnostic imaging The catheter 20 can effectively perform diagnostic intracardiac and transvascular imaging. This application will more than likely be performed just prior to an interventional application. The intervention then will follow using the same catheter system and its unique delivery capability.
- diagnostic imaging include 1) accurate visualization and measurement of an intracardiac defect, 2) characterization of valve orifice, 3) localization of a tumor and its connections, 4) etc.
- Extravascular diagnoses would include 1) visualize pancreatic mass/pathology, 2) retroperitoneal pathology, 3) intracranial imaging. 4) recognition of perivascular pathology, and 5) etc. 2.
- Application imaging refers to the use of the catheter and its imaging capability to deliver and then apply another technology such as 1) occlusion device for closure of a septal defect, 2) ablation catheters for treatment of bypass tracts, 3) creation of a defect such as that with the blade septostomy catheter or laser-based catheter system, and 4) directing of valvuloplasty, etc.
- direct imaging of an application such as ablation, the procedure will be able to be performed more safely and repeatedly, and the result can be better assessed.
- Hemodynamics The catheter 20 is a truly combined ultrasound Doppler and conventional hemodynamic catheter. There are Doppler catheters, and there are catheters capable of imaging and measuring hemodynamic pressure.
- the catheter 20 is capable of Doppler hemodynamics (continuous and pulsed-wave Doppler) as well as high-fidelity hemodynamic pressure recording while simultaneously imaging the heart and blood vessel.
- the catheter 20 provides a combination of imaging, hemodynamic, and interventional delivery catheter.
- intracardiac ultrasound is capable of 1) imaging, 2) delivering a therapeutic device, and 3) obtaining simultaneous hemodynamics which can be used to develop less invasive cardiac surgical techniques.
- This simultaneous use of one or more devices within the heart or vascular tree opens up the potential to develop less invasive surgical therapies.
- Examples would include 1) removal of a cardiac tumor by visually grasping the tumor with one device and visually cutting its attachment with a second device, thus allowing less invasive extraction of intracardiac mass lesions, 2) visually placing an electrophysiologic catheter on a bypass tract and then with direct ultrasound visualization ablate the underlying tract with the second device, 3) visually performing laser surgery such as creating an intra-atrial defect, vaporization of obstructing thrombus such as is seen in pseudointimal occlusion of conduits, 4) visually removing a foreign body from the heart or vascular tree, and 5) directing intravascular surgery from within a blood vessel or monitoring concomitant hemodynamic changes.
- Radio frequency ablation Presently a bypass tract is localized by an electrophysiologic study which systematically maps the atrioventricular valve annulus. Positioning of the ablation catheter is determined by x- ray fluoroscopy and certain electrical measurements which relate the distance of the ablation catheter from a reference catheter. The catheter 20 will allow an operator to map the atrioventricular valve under direct ultrasound visualization. Thus, increased accuracy of catheter placement, precision of the applied therapy, and immediate assessment of outcome would result.
- the above ablation technique would be particularly applicable for right-sided bypass 5 tracts (in and around the tricuspid valve annulus) . This would be accomplished by placement of the catheter 20 through the superior vena cava above the tricuspid annulus. 10 For left-sided bypass tracts, the catheter
- mitral annulus 20 could be placed across the atrial septum under direct ultrasound visualization.
- the mitral annulus could thus be mapped directly and the localized bypass tract precisely 15 ablated under visual ultrasonic and hemodynamic direction. Complications such as valve perforation, multiple imprecise applications of ablation energy, and inadvertent ablation of normal conduction 20 tissue would be substantially reduced.
- Ultrasound direction of the biopsy device to an intracardiac tumor, avoidance of scar, and selective biopsy of suspect tissue are feasible with the catheter 20 device.
- One of 30 the more frequently life-threatening complications in the cardiac catheterization laboratory is catheter perforation of the heart. Such complications most commonly accompany cardiac biopsy, electrophysiologic 35 catheter manipulation, and valvuloplasty.
- Use of an intracardiac ultrasound imaging, hemodynamics, and delivery catheter should substantially increase or improve safety of these procedures.
- Transvascular diagnoses The catheter 20 will allow visualization of perivascular and extravascular pathology. Transvascular or transorgan imaging and localization of pathology out of the immediate vascular tree will result in a substantial step forward in the diagnosis and possible treatment of difficult to reach pathology.
- the catheter 20 cannot only diagnose but guide a biopsy needle and therapeutic device to an extravascular lesion in question.
- the retroperitoneum, mediastinum, and basal cerebrovascular pathology are logical areas of interest.
- vascular system is a conduit to each organ, and the catheter 20 can be delivered to each organ. Characterization of the underlying parenchyma and possible transvascular biopsy or treatment will ultimately be developed.
- the catheter 20 opens the potential not only to visualize but to directly intervene with the same catheter system.
- There are numerous intraoperative catheter-based systems which to date use conventional x-ray to accomplish their goal of placement and application of a specified therapy.
- the catheter 20 has all the prerequisites of an ideal imaging and interventional instrument and has the ability to 1) image, 2) obtain hemodynamics by multiple means (pressure dynamics and Doppler, 3) function as a diagnostic as well as therapeutic device, and 4) accommodate other unique technologies which would enhance the application of both systems.
- intravascular, transvascular, and intracardiac devices could be delivered through the port means described above within or about the heart and blood vessels of the body.
- the catheters described above could also be used in any echogenic tissue, such as liver, parenchyma, bile ducts, ureters, urinary bladder, and intracranial - i.e., any place in the body which is echogenic which would allow passage of a catheter for either diagnostic or therapeutic applications using ultrasound visualization.
- the catheter 20 is a new and exciting innovation to invasive medicine. There are multiple • other and yet-to-be-determined applications. However, the new concept described opens the potential development of less expensive, more precise, and safe intravascular and transvascular diagnostic and surgical devices.
- the catheter 20 is very much different from any conventional ultrasound catheter-based system.
- the catheter 20 incorporates image and hemodynamic capability as well as the ability to deliver other diverse technologies to specified sites within the cardiovascular system (heart and blood vessels).
- the catheter 20 is seen as an ideal diagnostic and therapeutic tool for future development.
- the proposed applications foster greater preciseness, adaptability, and safety.
- Ultrasound permits visualization from within blood-filled spaces as well as through blood-filled spaces into other water- or fluid-filled tissue.
- the catheter 20 will evolve into the ultimate interventional system.
- FIG. 4 is an illustration showing one potential use of the ultrasound imaging and hemodynamic catheter (UIHC) .
- the UIHC is advanced from the superior vena cava to the tricuspid valve annulus. Simultaneously visualized in the annulus, electrophysiologic and ultimately and ablation procedure are performed. The ability to directly visualize and direct therapeutic catheter devices highlights only one of the many applications of the UIHC.
