Definitions
- the present invention relates generally to implantable access ports and attachment mechanisms or systems for attaching the implantable access ports to a patient. More specifically, the present invention relates to implantable access ports with independent moving gears for the anchors, and related actuation devices.
- Implantable medical devices for performing therapeutic functions for a patient are well known. Such devices include pace makers, vascular access ports, injection ports (such as those used with gastric banding devices) and gastric pacing devices. Such devices are attached to a human, typically subcutaneously, in an appropriate place in order to function properly. It is desirable that the procedure to implant such devices be quick, easy, efficient, and require as small of an incision as possible.
- a suture (also known as stitches) is typically used by doctors to hold skin, internal organs, blood vessels and all other tissues of the human body together after they have been severed by injury, incision or surgery. Suturing is both time consuming and inconvenient.
- Surgical fasteners such as staples, clips, clamps, bands, tacks, or other wound or incision closure devices, have been used in surgical procedures to eliminate the need for suturing.
- Surgical fasteners are commonly used in surgical procedures to allow a surgeon to fasten, secure, and/or repair bodily tissue. In these applications, the surgeon often uses a fastener implanting device loaded with one or more surgical fasteners to accomplish in a few seconds what would have taken many minutes to perform by suturing. This reduction in operating time reduces blood loss and trauma to the patient.
- surgical fasteners have been used mainly for the closure of incisions or wounds, or to fasten tissues together.
- a surgical fastener that can be used with a number of different types of implantable medical devices would be beneficial for surgeons.
- surgical systems that incorporate surgical fasteners often use extremely specialized devices that may be unnecessarily complicated and are unsuitable for adaptation to other applications.
- the majority of implantable medical devices are secured with sutures.
- the associated access port may be sutured into place with 3 to 5 sutures against the rectus muscle sheath.
- Such placement of the sutures is often challenging because the associated access port is placed below several inches of bodily tissue (e.g., fat), and suturing the associated access port often takes as long as placing the gastric band itself.
- An improved fastening device would allow easy, one-step attachment with security equivalent to the sutured medical device.
- the external pistol may include a trigger having geared teeth, a gear which meshes with the geared teeth, and a spring.
- the external pistol attaches to the implantable access port and tightens a fastener into the tissue of the patient upon pressing of the trigger. After attachment, the external pistol is removed from the implantable access port. Examples of similar methods may be found in European Patent Application Pub. No. 1736194 and U.S. Patent Application Pub. No. 2005/0283118.
- Another conventional method for fastening an implantable access port includes fasteners extending from the housing of the implantable access port.
- the implantable access port may be self-attached upon the surgeon applying a distal force to the access port housing, causing the fasteners to penetrate the tissue, engaging the tissue to hold the access port in place. Examples of similar methods may be found in U.S. Patent Application Pub. Nos. 2004/0254537, 2006/0190039, 2006/0235445, and 2009/0259190.
- the fasteners may be electronically switched between a deployed position and an un-deployed position using an actuator.
- European Patent Application Pub. No. 1543861 and U.S. Patent Application Pub. No. 2005/0131352 disclose an injection port that may be implanted using separate fasteners that are not part of the port prior to implantation. These fasteners are inserted one at a time using a tool. Thus, the tool is repositioned prior to implanting each fastener, which may lead to inefficiencies and inaccuracies in the implantation.
- U.S. Pat. No. 7,374,557 also discloses individually inserted fasteners.
- the present invention overcomes at least some of the drawbacks of these conventional medical devices and methods.
- implantable access ports and related actuation devices Generally described herein are implantable access ports and related actuation devices.
- the apparatus, systems and methods described herein provide relatively easy attachment capabilities of the implantable access ports to bodily tissue.
- an implantable injection port comprises a base with a first anchor opening.
- a first gear is coupled to the base and is rotatable about a first axis, and a first anchor is coupled to the first gear.
- a second gear is coupled to the base and is rotatable about a second axis, and a second anchor is coupled to the second gear.
- the first gear has a first plurality of gear teeth
- the second gear has a second plurality of gear teeth.
- a top portion of the injection port is spaced apart from the base of the port and has a first plurality of top teeth that engage with the first plurality of gear teeth on the first gear. This engagement occurs prior to rotation of the second gear.
- the top portion rotates, which causes rotation of the first gear, which in turn causes movement of the first anchor through the anchor opening of the base and into the tissue of the patient.
- the first gear rotates about the first axis independently of the second gear rotating about a second axis and prior to the second anchor being implanted in the tissue of the patient.
- the first gear and the second gear rotate non-simultaneously.
- an actuation device for attaching an implantable injection port comprises a head for coupling to the implantable injection port.
- a first drive band is coupled to a trigger of the actuation device, and a second drive band is coupled to the first drive band for translating motion from the trigger of the actuation device to the second drive band.
- the second drive band interfaces with a top portion of the implantable injection port to facilitate deploying an anchor of the implantable injection port into the tissue of the patient.
- a switch on a housing of the actuation device is operable to direct the second drive band to rotate the top portion of the implantable injection port in an implanting direction or a retracting direction.
- a method for implanting an implantable injection port comprises coupling a gripping portion of an actuation device to a top portion of the implantable injection port.
- a trigger of the actuation device is depressed when a switch in the actuation device is located in an implanting orientation.
- a vertical drive band is then directed through the switch to contact the top portion of the implantable injection port and rotate the top portion in an implanting direction.
- a first anchor coupled to a first gear is implanted into the tissue of the patient in response to a first set of top teeth causing the first gear to rotate.
- a second anchor coupled to a second gear is implanted into the tissue of the patient in response to the first set of top teeth or a second set of top teeth causing the second gear to rotate.

Abstract
An implantable injection port comprises a base. A first gear is coupled to the base, and a first anchor is coupled to the first gear. A second gear is coupled to the base, and a second anchor is coupled to the second gear. A top portion of the injection port is spaced apart from the base of the port and has a first plurality of top teeth that engage with a first plurality of gear teeth on the first gear. This engagement occurs prior to rotation of the second gear. The top portion rotates, which causes rotation of the first gear, which in turn causes movement of the first anchor through the anchor opening of the base and into the tissue of the patient. The first gear and the second gear rotate non-simultaneously.
Description
- 1. Field
- The present invention relates generally to implantable access ports and attachment mechanisms or systems for attaching the implantable access ports to a patient. More specifically, the present invention relates to implantable access ports with independent moving gears for the anchors, and related actuation devices.
- 2. Description of the Related Art
- Implantable medical devices for performing therapeutic functions for a patient are well known. Such devices include pace makers, vascular access ports, injection ports (such as those used with gastric banding devices) and gastric pacing devices. Such devices are attached to a human, typically subcutaneously, in an appropriate place in order to function properly. It is desirable that the procedure to implant such devices be quick, easy, efficient, and require as small of an incision as possible.
- A suture (also known as stitches) is typically used by doctors to hold skin, internal organs, blood vessels and all other tissues of the human body together after they have been severed by injury, incision or surgery. Suturing is both time consuming and inconvenient. Surgical fasteners, such as staples, clips, clamps, bands, tacks, or other wound or incision closure devices, have been used in surgical procedures to eliminate the need for suturing. Surgical fasteners are commonly used in surgical procedures to allow a surgeon to fasten, secure, and/or repair bodily tissue. In these applications, the surgeon often uses a fastener implanting device loaded with one or more surgical fasteners to accomplish in a few seconds what would have taken many minutes to perform by suturing. This reduction in operating time reduces blood loss and trauma to the patient.
- Typically, such surgical fasteners have been used mainly for the closure of incisions or wounds, or to fasten tissues together. A surgical fastener that can be used with a number of different types of implantable medical devices would be beneficial for surgeons. Currently, surgical systems that incorporate surgical fasteners often use extremely specialized devices that may be unnecessarily complicated and are unsuitable for adaptation to other applications.
- As a result, the majority of implantable medical devices are secured with sutures. For example, when inserting a gastric band and an associated access port, the associated access port may be sutured into place with 3 to 5 sutures against the rectus muscle sheath. Such placement of the sutures is often challenging because the associated access port is placed below several inches of bodily tissue (e.g., fat), and suturing the associated access port often takes as long as placing the gastric band itself. An improved fastening device would allow easy, one-step attachment with security equivalent to the sutured medical device.
- One conventional method for fastening an implantable access port to the patient includes an external pistol-like applying means. The external pistol may include a trigger having geared teeth, a gear which meshes with the geared teeth, and a spring. The external pistol attaches to the implantable access port and tightens a fastener into the tissue of the patient upon pressing of the trigger. After attachment, the external pistol is removed from the implantable access port. Examples of similar methods may be found in European Patent Application Pub. No. 1736194 and U.S. Patent Application Pub. No. 2005/0283118.
- Another conventional method for fastening an implantable access port includes fasteners extending from the housing of the implantable access port. In a self-attaching method, the implantable access port may be self-attached upon the surgeon applying a distal force to the access port housing, causing the fasteners to penetrate the tissue, engaging the tissue to hold the access port in place. Examples of similar methods may be found in U.S. Patent Application Pub. Nos. 2004/0254537, 2006/0190039, 2006/0235445, and 2009/0259190. In an electronic method, the fasteners may be electronically switched between a deployed position and an un-deployed position using an actuator.
- European Patent Application Pub. No. 1543861 and U.S. Patent Application Pub. No. 2005/0131352 disclose an injection port that may be implanted using separate fasteners that are not part of the port prior to implantation. These fasteners are inserted one at a time using a tool. Thus, the tool is repositioned prior to implanting each fastener, which may lead to inefficiencies and inaccuracies in the implantation. U.S. Pat. No. 7,374,557 also discloses individually inserted fasteners.
- The present invention overcomes at least some of the drawbacks of these conventional medical devices and methods.
- Generally described herein are implantable access ports and related actuation devices. The apparatus, systems and methods described herein provide relatively easy attachment capabilities of the implantable access ports to bodily tissue.
- In one example embodiment, an implantable injection port comprises a base with a first anchor opening. A first gear is coupled to the base and is rotatable about a first axis, and a first anchor is coupled to the first gear. A second gear is coupled to the base and is rotatable about a second axis, and a second anchor is coupled to the second gear. The first gear has a first plurality of gear teeth, and the second gear has a second plurality of gear teeth.
- A top portion of the injection port is spaced apart from the base of the port and has a first plurality of top teeth that engage with the first plurality of gear teeth on the first gear. This engagement occurs prior to rotation of the second gear. The top portion rotates, which causes rotation of the first gear, which in turn causes movement of the first anchor through the anchor opening of the base and into the tissue of the patient. The first gear rotates about the first axis independently of the second gear rotating about a second axis and prior to the second anchor being implanted in the tissue of the patient. Thus, the first gear and the second gear rotate non-simultaneously.
- In another embodiment of the present invention, an actuation device for attaching an implantable injection port comprises a head for coupling to the implantable injection port. A first drive band is coupled to a trigger of the actuation device, and a second drive band is coupled to the first drive band for translating motion from the trigger of the actuation device to the second drive band. The second drive band interfaces with a top portion of the implantable injection port to facilitate deploying an anchor of the implantable injection port into the tissue of the patient. A switch on a housing of the actuation device is operable to direct the second drive band to rotate the top portion of the implantable injection port in an implanting direction or a retracting direction.
- Further, in accordance with an embodiment, a method for implanting an implantable injection port comprises coupling a gripping portion of an actuation device to a top portion of the implantable injection port. A trigger of the actuation device is depressed when a switch in the actuation device is located in an implanting orientation. A vertical drive band is then directed through the switch to contact the top portion of the implantable injection port and rotate the top portion in an implanting direction.
- At a first time, a first anchor coupled to a first gear is implanted into the tissue of the patient in response to a first set of top teeth causing the first gear to rotate. At a second time, a second anchor coupled to a second gear is implanted into the tissue of the patient in response to the first set of top teeth or a second set of top teeth causing the second gear to rotate.

FIG. 1 is a simplified partial front view of ahuman body 105 with a food intake restriction system, such as an implantablegastric banding system 100 having aband 110, aport 130 and anapplier 135 according to an embodiment of the present invention. Thegastric banding system 100 is used to treat obesity and to attach to a tissue of a patient. Theband 110 may be a gastric band, such as the Lap-Band®, and may be adjustable, implantable, inflatable and positioned around or near the upper portion of astomach 120 of a human 105. Generally, theband 110 is placed about the fundus, or esophageal junction, of a patient's upper stomach forming a stoma that restricts the food's passage into a lower portion of the stomach. Theband 110 may include an inflatable portion (e.g., a cavity) made of silicone rubber, or another type of biocompatible material, that inflates or expands inward to constrict the stoma (stomach inlet) when filled with a fluid (e.g., saline) from the tubing, such as acatheter 125. Alternatively, a mechanical device or a combination hydraulic/mechanical device may be coupled to theband 110 to constrict the stoma. When the stoma is of an appropriate size that is restricted by theband 110, food held in the upper portion of the stomach may provide a feeling of satiety or fullness that discourages overeating. - The
port 130 may be implanted in a body region accessible for needle injections from asyringe 140 and/or for receiving telemetry communication signals. Theport 130 is a medical device that may be referred to as an access port, an injection port, an implantable access device/port or a housing. Theport 130 fluidly communicates with the inflatable portion of theband 110 via thecatheter 125. - A medical professional (e.g., doctor, health care provider, nurse, surgeon, technician, etc.) may position and temporarily or permanently implant the
port 130 inside the body of the human 105 in order to perform adjustments of the food intake restriction or stoma created by theband 110. The medical professional, for example, may implant theport 130 in the lateral, subcostal region of the human's abdomen under the skin and layers of fatty tissue, or on or near the sternum of the human 105. Also, any other suitable attachment areas or port sites may be used. - The
applier 135 may be used to secure theport 130 to the human 105, as depression of an applier trigger facilitates rotation of a portion of theport 130 to secure anchors of theport 130 into bodily tissue of the human 105. In particular, the anchors may be moved from an undeployed position to a deployed position. Theapplier 135 may be a tool such as a delivery tool. -

FIGS. 2A-4 , theport 130 is configured to receive fluid from thesyringe 140 for movement into the inflatable portion of theband 110. Theport 130 includes thetop portion 205 and thereservoir 410. Thereservoir 410 contains an interior space for holding the fluid. Thereservoir 410 may be an internal titanium port reservoir or a port without thetop portion 205. As shown inFIG. 4 , thereservoir 410 is formed in the shape of a cylinder. - The
top portion 205 may be a drive cap, a port cap, a rotating cap, a top cap or a top outer ring. Thetop portion 205 may have alip 261 that facilitates rotating thetop portion 205 to implant theport 130, and alip 262 that facilitates rotating thetop portion 205 to remove theport 130, as discussed further below. Thetop portion 205 may be attached to or may be integrally formed with aninner ring 206. Theinner ring 206 may also be referred to as a flange. Alternatively, thetop portion 205 may include theinner ring 206. - The
top portion 205 may have acenter opening 207. Thecenter opening 207 allows theinner ring 206 to fit therein. In addition, a septum 215 (e.g., a needle penetrable septum) may be located or positioned within theinner ring 206 and/or the center opening 207 of thetop portion 205. Theinner ring 206 and/or theseptum 215 may be attached to thereservoir 410. Thetop portion 205 may rotate without rotating theinner ring 206 and/or theseptum 215. That is, theinner ring 206 and/or theseptum 215 may be permanently attached or fixedly attached to thereservoir 410. In one embodiment, thetop portion 205 is moveably or rotatably attached to theinner ring 206. - As an example, the
syringe 140 may be used to pierce theseptum 215, thus allowing the fluid in thesyringe 140 to pass into thereservoir 410 and then ultimately through thecatheter 125 and into the inflatable portion of theband 110. Also, thesyringe 140 may be used to remove fluid from thereservoir 410, which causes the fluid in the inflatable portion of theband 110 to be removed therefrom. Theseptum 215 may be made of any suitable needle penetrable material, for example, a self sealing, needle penetrable material. - The
port 130 has abase 245, one ormore axles 350, one or more axle holders 451, one ormore gears 375 and one or more anchors 255. Theanchors 255 and thegears 375 may be formed as one piece, or as separate pieces that may be joined together. The base 245 may also be referred to as a port base, a bottom base, a bottom cap, a bottom ring or a bottom portion. The base 245 may lie along a plane that is substantially parallel to the plane defined by thetop portion 205. Thereservoir 410 is fixedly attached to thebase 245 and does not move with the rotation of thetop portion 205. - The
base 245 includes one ormore anchor openings 365 and one ormore tip openings 370. As an example, the one ormore anchor openings 365 may be formed in the shape of a rectangle and the one ormore tip openings 370 may be formed in the shape of a circle. Theanchors 255 may be locked into place in the base 245 after deployment using a flat interference locating feature, for example, in theanchor openings 365. Ahousing 200 is disposed about thereservoir 410, between the base 245 and the top cover 250. - The axle holder 451 is attached to or integrated with the
base 245. The axle holder 451 may include twopylons axle 350 to pass therethrough (seeFIG. 4 ). The twopylons anchor opening 365. Theanchor 255 and thegear 375 also have openings that allow for theaxle 350 to pass therethrough. The component with theanchor 255 and thegear 375 fit between the twopylons axle 350 passes through the holes of thepylon 451 a, theanchor 255, thegear 375, and thepylon 451 b and is positioned therein. The rotational movement of thegear 375 causes a similar circular or rotational movement of theanchor 255. - The
axle 350 may rotate circularly when force is applied thereon. Theaxle 350 may also be referred to as a center pin. Thegear 375, attached to theaxle 350, may rotate in unison with and/or about theaxle 350. - The base 245 may be moveably attached to the
top portion 205 by thereservoir 410. Astem 240 is attached to thereservoir 410 for moving the fluid from theport 130 to theband 110. Thestem 240 may include a strain relief element which locks into ahousing 200 and protects thecatheter 125 from folding, kinking, rotating, or torquing when thecatheter 125 is connected to thereservoir 410. Thehousing 200 may also be referred to as a port housing. Thehousing 200 surrounds theport 130 and covers the components therein. - A
radiopaque marker 420 is a type of locator element on theport 130 that is visible under an x-ray. Theradiopaque marker 420 may be secured in thehousing 200 so as not to hide theradiopaque marker 420. Theradiopaque markers 420 can be used to facilitate identification of the type of gastric band or other useful information to be identified by the x-ray image of theport 130, for example, by using varied configurations, sizes or shapes of theradiopaque marker 420. - In accordance with an embodiment, the
housing 200, thebase 245, thetop portion 205, and thegears 375 may be made of implantable grade plastic. Further, theanchors 255, the axels 250, and theradiopaque markers 420 may be made of implantable grade metal. Additionally, thereservoir 410 may be made of implantable grade titanium, and theseptum 215 may be made of implantable silicone. It should be understood that other materials are contemplated within the scope of the present invention, and the above are only representative materials according to an embodiment. - In an embodiment, the
port 130 may be assembled as follows. Theanchor 255 and thegear 375 structure and/or assembly is inserted between thepylons pylons pylon 451 a. The above process is repeated until all of theanchors 255 and thegears 375 are assembled. In an embodiment, theanchors 255 are assembled in a fully deployed position. Thereservoir 410 and thestem 240 subassembly are then inserted into thebase 245, for example, by leading with thestem 240 and coming in from the bottom of thebase 245. Thestem 240 may be aligned over a supporting block on thebase 245. Then, theseptum 215 may be inserted into thereservoir 410. Thehousing 200 is then aligned with theradiopaque markers 420 and inserted, following which thetop portion 205 is aligned and inserted. Theinner ring 206 or a port cover may then be inserted and pressed into place around theseptum 215 and within thetop portion 205. - In accordance with various embodiments,
FIGS. 5A-5C illustrate anapplier 135 that is configured to interface with thetop portion 205 of theport 130. Theapplier 135 includes anapplier housing 539 and ahousing top cover 538. Theapplier 135 further includes a head or agripping portion 581 configured to mate with thetop portion 205 of theport 130. - A
trigger 582 is movably coupled to theapplier housing 539 to allow a physician to actuate theport 130 in order to implant theanchors 255. Thetrigger 582 is biased away from theapplier housing 539 via aspring 563. Thetrigger 582 is also coupled to apulley 583. Thepulley 583 is coupled to afirst drive band 584, and thefirst drive band 584 is coupled to asecond drive band 586 to facilitate actuating theport 130, as will be described further below. The first andsecond drive bands applier 135 may be made of plastic and/or may be designed to be disposable. Aswitch 587 is operatively coupled to theapplier housing 539 to direct thesecond drive band 586 in an implanting direction or a removal direction to facilitate implanting or removing theport 130, which will also be discussed further below. - In accordance with an embodiment of the present invention, and with reference to
FIGS. 6A-6B , thefirst drive band 584 may be referred to as a horizontal drive band. To clarify, and with reference specifically toFIG. 6A , in an embodiment, thefirst drive band 584 may be a substantially flat drive band with a horizontal orientation, with respect to thegripping portion 581 of theapplier 135, where thefirst drive band 584 mates with thesecond drive band 586. - Further, in an embodiment, the
second drive band 586 may be referred to as a vertical drive band because of the second drive band's 586 vertical orientation, with respect to thegripping portion 581, where thefirst drive band 584 mates with thesecond drive band 586. Such a configuration allows thefirst drive band 584 to curve up theapplier housing 539, and allows thesecond drive band 586 to curve with respect to the curvature of thegripping portion 581 of theapplier 135. Other orientations and geometries of thedrive bands top portion 205 of theport 130 in response to a depression of thetrigger 582 are contemplated within the scope of the present invention. - The
switch 587 may further comprise aswitch channel 590 configured to receive thesecond drive band 586 and direct thesecond drive band 586 through afirst band channel 588 a or asecond band channel 588 b in theapplier 135. Theswitch 587 may rotate automatically or manually to direct thesecond drive band 586 down theappropriate band channel switch 587 depending on whether or not theport 130 will be implanted or removed. In another embodiment, theswitch 587 may automatically toggle to a removal position after thetrigger 582 is depressed and released to implant theport 130. - For example, to implant the
port 130, theswitch channel 590 may direct thesecond drive band 586 through thefirst band channel 588 a so that thesecond drive band 586 moves clockwise along afirst band surface 589 a of thegripping portion 581.FIGS. 6C-6D illustrate the extendedsecond drive band 586 along thefirst band surface 589 a to illustrate the motion along thefirst band surface 589 a (without showing the connected port 130) according to an embodiment of the present invention. With momentary reference toFIGS. 8A-8B , in accordance with an embodiment, a partial perspective view of theapplier 135 gripping theport 130 is shown, with thesecond drive band 586 passing through the switch, but prior to beginning rotation of thetop portion 205 to implant theport 130. - In this manner, the
second drive band 586 may be configured to interface with thetop portion 205 of theport 130 to rotate thetop portion 205 in a clockwise fashion in order to implant theanchors 255 in the tissue of thepatient 105. For example, with reference also toFIGS. 2A , 11, and 13-14, thesecond drive band 586 may be configured to interface with alip 261 on thetop portion 205 to facilitate rotating thetop portion 205 clockwise by pushing against thelip 261. - The
lip 261 may be referred to as an implanting lip because thesecond drive band 586 pushes against the implantinglip 261 to implant theport 130. A similar lip 262 (seeFIG. 2A ) may be located on another part of thetop portion 205 to allow thesecond drive band 586 to push against thelip 262 to rotate thetop portion 205 counter-clockwise. Thelip 262 may be referred to as a removal lip because thesecond drive band 586 pushes against theremoval lip 262 to remove theport 130. - Accordingly, the
first band channel 588 a may be referred to as an implanting band channel, thefirst band surface 589 a may be referred to as an implanting band surface, and thesecond drive band 586 may cause thetop portion 205 to move in an implanting direction by pushing against thelip 261 when thesecond drive band 586 moves through the implantingband channel 588 a and along the implantingband surface 589 a. - Similarly, to remove the
port 130, theswitch channel 590 may direct thesecond drive band 586 through thesecond band channel 588 b so that thesecond drive band 586 moves counter-clockwise along asecond band surface 589 b of thegripping portion 581.FIGS. 6E-6F illustrate the extendedsecond drive band 586 along thesecond band surface 589 b to illustrate the motion along thesecond band surface 589 b (without showing the connected port 130) according to an embodiment of the present invention. - In this manner, the
second drive band 586 may be configured to interface with thetop portion 205 of theport 130 to rotate thetop portion 205 in a counter-clockwise fashion in order to remove theanchors 255 from the tissue of thepatient 105. For example, thesecond drive band 586 may interface with a lip 262 (seeFIG. 2A ), ridge, or other structure on thetop portion 205 to facilitate pushing on the structure to rotate thetop portion 205 in a counter-clockwise direction. Thelip 262 may be referred to as a removal or an extraction lip because thesecond drive band 586 pushes against theremoval lip 262 to remove theport 130. - Accordingly, the
second band channel 588 b may be referred to as a removal band channel, thesecond band surface 589 b may be referred to as a removal band surface, and thesecond drive band 586 may cause thetop portion 205 to move in a removal direction when thesecond drive band 586 moves through theremoval band channel 588 a and along theremoval band surface 589 a. However, in other embodiments, it should be understood that thetop portion 205 of theport 130 may be rotated counter-clockwise to implant theanchors 255 and rotated clockwise to remove theanchors 255. In various embodiments, theapplier 135 may provide a tactile response, for example, through thetrigger 582, to indicate implantation and/or removal of theanchors 255. - In various embodiments, the
applier tool 135 may be assembled as follows. Thevertical drive band 586 and thehorizontal drive band 584 may be assembled together using a snap fit or an assembly pin, or other suitable attachment mechanism. Thehorizontal drive band 584 may then be inserted into thetrigger 582, for example, into a groove in thepulley 583. A snap fit, assembly pin, or other suitable mechanism may be used to attach thehorizontal drive band 584 to thetrigger 582. Thespring 563 is then inserted into thetrigger 582, and the assembly is inserted into theapplier housing 539. Theswitch 587 is then inserted into thehousing 539, and thehousing top cover 538 is then secured to thehousing 539, for example, by bonding thetop cover 538 and thehousing 539 together using epoxy or ultrasonic welding. - With reference to
FIGS. 7A-7B , in accordance with an embodiment, thetop portion 205 may comprise one or more fittings 707 (e.g., cavities, holes, snap bosses, or notches) located on a surface of thetop portion 205 to allow theapplier 135 to attach to or mate with thetop portion 205. Thefittings 707 may be referred to as snap fittings or bosses because theapplier 135 may snap into and out of thefittings 707. Thefittings 707 may interface with mating snap leaves 709 on theapplier 135. In one embodiment, thetop portion 205 rotates in a clockwise or counter-clockwise direction as guided by theapplier 135 to facilitate implanting theport 130 into or removing theport 130 from the patient's tissue. Theport 130 may be released from theapplier 135 by slightly lifting and then retracting theapplier 135. - With reference to
FIG. 9 , in an embodiment, thetop portion 205 of theport 130 may have top teeth 930 protruding from a bottom surface of thetop portion 205. In an example embodiment, the top teeth 930 are positioned about an axis that is substantially perpendicular to a plane defined by thetop portion 205. The top teeth 930 include ridges, alternating cut-outs and protrusions, bumpy or uneven surfaces, a flat surface with friction and/or any other surface(s) with sufficient friction to interact with and move components (e.g., thegear 375 and the anchor 255) of theport 130. Various sets or pluralities of top teeth 930 (e.g., a first set/plurality of top teeth, a second set/plurality of top teeth, etc.) may be positioned along an outer edge of thetop portion 205 for interacting withdifferent gears 375 at different or the same times. - The
gear 375 may also be referred to as a pinion gear. Theteeth 380 on thegear 375 mate with the top teeth 930 of thetop portion 205 to rotate theanchor 255. Theteeth 380 and top teeth 930 may include ridges, bumpy surfaces, flat surfaces with friction, and any other surface with sufficient friction to interact with and to move components of theport 130. - With reference to
FIG. 10 , and in accordance with an embodiment, to deploy theanchor 255, thetop portion 205 is rotated in a clockwise direction and the top teeth 930 are engaged with theteeth 380 to rotate thegear 375 and theanchor 255 in a counter-clockwise direction causing theanchor 255 to move through theanchor opening 365 and into the tissue of a patient. In an embodiment, and with reference toFIG. 11 , theanchor tip 460 may also move into thetip opening 370 when theanchor 255 is fully deployed. - The
anchor 255 secures theport 130 to the human 105, by theanchor tip 460 penetrating the human's skin or muscle (e.g., abdominal muscle fascia). Theanchor tip 460 may also be referred to as a hook or pointed end. Theanchor tip 460 is structured to penetrate and enter the bodily tissue as theanchor 255 rotates into the deployed position. - In some embodiments, the
anchor tip 460 includes one or more flat faces. For example, theanchor tip 460 may have a single facet, or may have two or more facets. Theanchor 255 may also be referred to as an attachment mechanism, a hook, a needle anchor, a needle device, or a cork screw. Also, theanchor 255 may be formed in the shape of a hook, a needle or a cork screw (e.g., a series of spirals with a sharp point at the end of the series of spirals). In one embodiment, eachanchor 255 may be made of a wire, for example, a bent stainless steel wire having a round cross section and a multi-faceted sharp distal tip. Theport 130 may include two, three, four, five ormore anchors 255 and related components that are attached and positioned equidistantly around thebase 245. - In one embodiment, a plurality of
anchors 255 are deployed or moved from an un-deployed position (see, e.g.,FIG. 9 ) to a fully-deployed position (see, e.g.,FIGS. 13B , 13C, and 14), or from a fully-deployed position to an un-deployed position. In various embodiments, someanchors 255 may be deployed or removed simultaneously. For example, where theport 130 has fouranchors 255, and with reference to FIGS. 10 and 11A-11B,opposite anchors 255 may be simultaneously deployed. Further, someanchors 255 may be deployed or removed non-simultaneously. For example, a first set of opposinganchors 255 a may be deployed or removed first, and then a second set of opposinganchors 255 b may be deployed or removed second (see, e.g.,FIG. 13A ). It should be understood that various other deployment combinations, both simultaneous and non-simultaneous, are contemplated within the scope of the present invention. - Each
anchor 255 is rotated from an un-deployed position where theanchor 255 is above the base 245 to a deployed position where theanchor 255 travels through theanchor opening 365. When in the deployed position, theanchors 255 fix theport 130 to the bodily tissue. If theport 130 is removed, theanchors 255 may be rotated from the deployed position back to the un-deployed position within theport 130. - In the case where the
port 130 is used in conjunction with thegastric band 110, theport 130 may be secured, by means of theanchors 255, to the rectus muscle fascia. Theanchor 255 may protrude through the anchor opening 365 in thebase 245, and may also protrude through thetip opening 370 in the base 245 as theanchor 255 is rotated around theaxle 350. Thetip opening 370 provides a safe storage position for theanchor tip 460 so theanchor tip 460 does not get dulled or damaged. - The base 245 may also have one or
more suture holes 285 for suturing theport 130 to the human 105, in the event that the use of theapplier 135 to attach theport 130 is not desired or allowable. A drawback of suturing is the additional time and effort required by the medical professional to secure theport 130 during surgery. - In some embodiments, the
anchors 255 are removable or reversible, allowing theanchors 255 to be detached from the bodily tissue. For example, thetop portion 205 can be rotated in a counter-clockwise direction to remove theanchors 255 from the tissue. Specifically, to un-deploy theanchors 255, thetop portion 205 is rotated in a counter-clockwise direction and the top teeth 930 are engaged with theteeth 380 to rotate thegear 375 and theanchor 255 in a clockwise direction causing theanchors 255 to move through theanchor opening 365 and out of the tissue. Theanchor tip 460 may also move into theanchor opening 365. - In one embodiment, a plurality of
anchors 255 includes four anchors that are evenly spaced apart around thebase 245. Eachanchor 255 may be referred to as being independent, which includes being a separate component or having separate operation from anotheranchor 255. Eachanchor 255 includes a curved distal portion such as theanchor tip 460 which engages the bodily tissue and a pivotal proximal portion or a body portion that includes thegear 375, which is rotatably connected to thebase 245 of theport 130. - As noted above, in various embodiments, the
anchors 255 are independently movable between a non-implanted and implanted position. Furthermore, theanchors 255 may be implanted or extracted simultaneously or non-simultaneously. To facilitate deployment of theanchors 255, the plurality of sets of top teeth 930 may be advantageously located around a circumference of thetop portion 205 so that the top teeth 930 interact with theteeth 380 at the appropriate time. - Although it should be understood that various numbers, configurations, and locations of the top teeth 930, the
gears 375, and theanchors 255 are contemplated within the scope of the present invention, the following is a description of a particular configuration according to an embodiment of the present invention. - With reference to
FIGS. 9 , 10, and 11A-B, and in accordance with an embodiment, thetop portion 205 includes four sets of top teeth 930. Each set of top teeth 930 is located to allow simultaneous or non-simultaneous deployment of theanchors 255. For example, the fouranchors 255 may be spaced equidistantly around the circumference of the port 130 (e.g., every ninety degrees), but the sets of top teeth 930 may not be equidistant. - To explain, a first set of the
anchors 255 a that are opposite each other may be deployed first, and a second set ofanchors 255 b (seeFIGS. 13A-13C ) that are opposite each other, but that neighbor the first set ofanchors 255 a, may be deployed second. A first set oftop teeth 930 a (as illustrated inFIG. 9 ) may interface with theteeth 380 a on afirst gear 375 a (or first set ofgears 375 a) to facilitate implanting afirst anchor 255 a (or first set ofanchors 255 a) into the patient's tissue. As illustrated in FIGS. 10 and 11A-11B, thesefirst anchors 255 a are implanted prior to implantation of a second set ofanchors 255 b (seeFIG. 13B-13C ). - In an embodiment, and with reference to
FIGS. 13A-13C and 14, after the first set oftop teeth 930 a moves through theteeth 380 a on the first set ofgears 375 a and the first set ofanchors 255 a are implanted, the second set oftop teeth 930 b interact with the second set ofteeth 380 b on the second set ofgears 375 b. In this manner, the second set oftop teeth 930 b cause the second set ofanchors 255 b to be implanted into the tissue of the patient after implantation of the first set ofanchors 255 a. Theanchors 255 may similarly be non-simultaneously removed from the patient's tissue in reverse of the above mentioned process (e.g., by rotating thetop portion 205 counter-clockwise). - Although two sets of
top teeth top portion 205. In this manner, the top teeth 930 may first come in contact with the first set ofteeth 380 a on the first set ofgears 375 a to facilitate implanting the first set ofanchors 255 a. As thetop portion 205 continues to rotate, the top teeth 930 may then come into contact with the second set ofteeth 380 b on the second set ofgears 375 b to facilitate implanting the second set ofanchors 255 b. Other configurations are contemplated within the scope of the present invention that facilitate non-simultaneous deployment of at least some of theanchors 255. - In accordance with various embodiments, non-simultaneous implantation of the
anchors 255 may be accomplished by moving theswitch 587 of theapplier 135 to an implantation position and then depressing thetrigger 582 of theapplier 135. Depressing thetrigger 582 causes thehorizontal drive band 584 to act on thevertical drive band 586, which moves through theswitch channel 590 and the implantingband channel 588 a. - By moving through the implanting
band channel 588 a, thevertical drive band 586 acts on the implantinglip 261 to cause thetop portion 205 to rotate in a clockwise manner to move the top teeth 930 over theteeth 380 of thegears 375 to implant theanchors 255 into the tissue of the patient. For example, the first set ofanchors 255 a may be deployed, and then the second set ofanchors 255 b may be deployed, resulting in non-simultaneous deployment of theanchors - In a reverse manner, and in accordance with various embodiments, non-simultaneous removal of the
anchors 255 may be accomplished by moving theswitch 587 of theapplier 135 to a removal position and then depressing thetrigger 582 of theapplier 135. Depressing thetrigger 582 causes thehorizontal drive band 584 to act on the vertical drive and 586, which moves through theswitch channel 590 and theremoval band channel 588 b. - By moving through the
removal band channel 588 b, thevertical drive band 586 acts on theremoval lip 262 to cause thetop portion 205 to rotate in a counter-clockwise manner to move the top teeth 930 over theteeth 380 of thegears 375 to remove theanchors 255 from the tissue of the patient. For example, the first set ofanchors 255 a may be removed, and then the second set ofanchors 255 b may be removed, resulting in non-simultaneous removal of theanchors - The terms “a,” “an,” “the,” and similar referents used in the context of describing the present invention (especially in the context of the following claims) are to be construed to cover both the singular and the plural, unless otherwise indicated herein or clearly contradicted by context.
