Description

    BACKGROUND
  • 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 and locking gears for the anchors and related actuation devices. The implantable access ports may be connected to an inflatable portion of a gastric band and may be used to fill and remove fluid from the inflatable portion of the gastric band.
  • 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.
  • 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. In an electronic method, the fasteners may be electronically switched between a deployed position and an un-deployed position using an actuator.
  • The present invention overcomes at least some of the drawbacks of these conventional medical devices and methods.
  • SUMMARY
  • Generally described herein are implantable access ports and related actuation devices. The apparatus, systems and methods described herein provide relatively easy attachment and locking capabilities of the implantable access ports to bodily tissue.
  • In one example embodiment, an implantable injection port for use with a gastric band for treating obesity and for attaching to a tissue of a patient is disclosed. The implantable injection port includes a base having an anchor opening, a gear coupled to the base and rotatable about a central axis, the gear having a plurality of gear teeth, an anchor coupled to the gear, and a top portion spaced apart from the base and having a plurality of top teeth that engage with the plurality of gear teeth. The top portion is rotatable causing rotation of the gear such that the rotation of the gear causes movement of the anchor through the anchor opening of the base and into the tissue of the patient.

  • DETAILED DESCRIPTION
  • Apparatus, systems and methods that implement the embodiments of the various features of the present invention will now be described with reference to the drawings. The drawings and the associated descriptions are provided to illustrate some embodiments of the present invention and not to limit the scope of the present invention. Throughout the drawings, reference numbers are re-used to indicate correspondence between referenced elements.
  • A system is disclosed having a port (e.g., an implantable access port or an implantable injection port) that is securely fastened to bodily tissue of a human or a patient. The port is used to fill and remove fluid from an inflatable portion of a band (e.g., a gastric band) via a catheter attached between the port and the inflatable portion of the band. One or more anchors (e.g., four anchors) of the port may be subcutaneously and securely attached to the bodily tissue of the human by rotating one or more mating components (e.g., an applier, an axle, a cap, a gear, etc.). The one or more mating components provide a continually secure attachment of the one or more anchors to the bodily tissue of the patient after surgery.
  • FIG. 1 is a simplified partial front view of a human body 105 with a food intake restriction system 100 having a band 110, a port 130 and an applier 135 according to an embodiment of the present invention. The food intake restriction system 100 is used to treat obesity and to attach to a tissue of a patient. The band 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 a stomach 120 of a human 105. Generally, the band 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. The band 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 a catheter 125. Alternatively, a mechanical device or a combination hydraulic/mechanical device may be coupled to the band 110 to constrict the stoma. When the stoma is of an appropriate size that is restricted by the band 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 a syringe 140 and/or for receiving telemetry communication signals. The port 130 is a medical device that may be referred to as an access port, an injection port, an implantable access device or a housing. The port 130 fluidly communicates with the inflatable portion of the band 110 via the catheter 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 the band 110. The medical professional, for example, may implant the port 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 the port 130 to the human 105, as rotation of an applier handle rotates a portion of the port 130 and secures anchors of the port 130 into bodily tissue of the human 105. In particular, the anchors may be moved from an undeployed position to a deployed position. The applier 135 may be a tool such as a delivery tool.
  • FIG. 2 is a perspective view of the port 130 according to an embodiment of the present invention. FIG. 3 is a top view of the port 130 of FIG. 2, illustrating a circular fitting 207 that connects to or meshes with the applier 135, according to an embodiment of the present invention. FIG. 4 is a perspective view of the port 130 of FIG. 2 with a top portion 205 removed to show the reservoir 210 according to an embodiment of the present invention. FIG. 5 is a disassembled perspective view showing the different parts of the port 130 of FIG. 2 according to an embodiment of the present invention.
  • Referring to FIGS. 1-5, the port 130 is configured to receive fluid from the syringe 140 for movement into the inflatable portion of the band 110. The port 130 includes the top portion 205 and the reservoir 210. The reservoir 210 contains an interior space for holding the fluid. The reservoir 210 may be an internal titanium port reservoir or a port without the top portion 205. As shown in FIG. 4, the reservoir 210 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. The top portion 205 may be attached to or be integrally formed with an inner ring 206. The inner ring 206 may also be referred to as a flange. Alternatively, the top portion 205 may include the inner ring 206.
  • The top portion 205 may have a center opening 207. The center opening 207 allows the inner ring 206 to fit therein. In addition, a septum 215 (e.g., a needle penetrable septum) may be located or positioned within the inner ring 206 and/or the center opening 207 of the top portion 205. The inner ring 206 and/or the septum 215 may be attached to the reservoir 210. The top portion 205 can rotate without rotating the inner ring 206 and/or the septum 215. That is, the inner ring 206 and/or the septum 215 may be permanently attached or fixedly attached to the reservoir 210. In one embodiment, the top portion 205 is moveably or rotatably attached to the inner ring 206.
  • As an example, the syringe 140 may be used to pierce the septum 215, thus allowing the fluid in the syringe 140 to pass into the reservoir 210 and then ultimately through the catheter 125 and into the inflatable portion of the band 110. Also, the syringe 140 may be used to remove fluid from the reservoir 210, which causes the fluid in the inflatable portion of the band 110 to be removed therefrom. The septum 215 may be made of any suitable needle penetrable material, for example, a self sealing needle penetrable material.
  • The top portion 205 may also have one or more fittings 207 (e.g., cavities, holes or notches) located on a top surface of the top portion 205 to allow the applier 135 to attach to or mate with the top portion 205. The fittings 207 may be referred to as snap fittings because the applier 135 can snap into and out of the fittings 207. Located in or near the fittings 207, can be a lock indicator 225, illustrating when the port 130 is securely attached to the bodily tissue of the human 105. For example, the lock indicator 225 can be a color-coded indicator on a bottom surface of the fittings 207 where a green color indicates a locked position and a red color indicates an unlocked position. The applier 135 can mate with the top portion 205 to rotate the top portion 205. In one embodiment, the top portion 205 rotates in a circular direction guided by the applier 135.
  • The top portion 205 may also have teeth 230 protruding from a bottom surface of the top portion 205. In an example embodiment, the teeth 230 are positioned along an axis that is substantially perpendicular to a plane defined by the top portion 205. The teeth 230 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., the gear 275 and the anchor 255) of the port 130. The teeth 230 may be positioned along an outer edge of the entire top portion 205 forming a circle.
  • The port 130 has a base 245, one or more axles 250, one or more axle holders 251, one or more gears 275 and one or more anchors 255. 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 the top portion 205. The reservoir 210 is fixedly attached to the base 245 and does not move with the rotation of the top portion 205. The base 245 includes one or more anchor openings 265 and one or more tip openings 270. As an example, the one or more anchor openings 265 may be formed in the shape of a rectangle and the one or more tip openings 270 may be formed in the shape of a circle.
  • The axle holder 251 is attached to or integrated with the base 245. The axle holder 251 may include two pylons 251 a and 251 b each having a hole for the axle 250 to pass therethrough (see FIG. 5). The two pylons 251 a and 251 b are positioned adjacent to and on opposite sides of the anchor opening 265. The anchor 255 and the gear 275 also have openings that allow for the axle 250 to pass therethrough. As shown in FIG. 5, the gear 275 may have a side groove 277 for holding the anchor 255 in place and allowing for simultaneous rotation. In an assembled state, a base portion 257 of the anchor 255 tightly fits into the side groove 277 of the gear 275 and the combined anchor 255 and gear 275 fit between the two pylons 251 a and 251 b. The axle 250 passes through the holes of the pylori 251 a, the anchor 255, the gear 275, and the pylori 251 b and is positioned therein. The movement of the gear 275 causes a similar circular or rotational movement of the anchor 255.
  • The axle 250 may rotate circularly when force is applied thereon. The axle 250 may also be referred to as a center pin. The gear 275, attached to the axle 250, may rotate in unison with the axle 250.
  • The gear 275 may also be referred to as a pinion gear. The gear includes teeth 280 which mate with the teeth 230 of the top portion 205 to rotate the anchor 255. The teeth 280 may include ridges, bumpy surfaces, flat surfaces with friction, and any other surface with sufficient friction to interact with and to move components of the port 130.
  • To deploy the anchor 255, the top portion 205 is rotated in a clockwise direction and the teeth 230 are engaged with the teeth 280 to rotate the gear 275 and the anchor 255 in a counter-clockwise direction causing the anchor 255 to move through the anchor opening 265 and into the tissue of a patient. An anchor tip 260 may also move into the tip opening 270 when the anchor 255 is fully deployed.
  • The anchor 255 secures the port 130 to the human 105, by the anchor tip 260 penetrating the human's skin or muscle (e.g., abdominal muscle fascia). The anchor tip 260 may also be referred to as a hook or pointed end. The anchor tip 260 is structured to penetrate and enter the bodily tissue as the anchor 255 rotates into the deployed position. In some embodiments, the anchor tip 260 includes one or more flat faces. For example, the anchor tip 260 may have a single facet, or may have two or more facets. The anchor 255 may also be referred to as an attachment mechanism, a hook, a needle anchor, a needle device, or a cork screw. Also, the anchor 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 (see FIGS. 24 and 25)). In one embodiment, each anchor 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. The port 130 may include two, three, four, five or more anchors 255 and related components that are attached and positioned an equi-distance around the base 245.
  • In one embodiment, a plurality of anchors 255 are simultaneously deployed or moved from an un-deployed position (FIG. 20) to a deployed position (FIG. 21). Each anchor 255 is rotated from an un-deployed position where the anchor 255 is above the base 245 to a deployed position where the anchor 255 travels through the anchor opening 265 and the base portion 257 of the needle 255 is in direct contact with the base 245. When in the deployed position, the anchors 255 fix the port 130 to the bodily tissue. In the case where the port 130 is used in conjunction with a gastric band, the port 130 may be secured, by means of the anchors 255, to the rectus muscle fascia. The anchor 255 may protrude through the anchor opening 265 in the base 245, and may also protrude through the tip opening 270 in the base 245 as the anchor 255 is rotated around the axle 250. The tip opening 270 provides a safe storage position for the anchor tip 260 so the anchor tip 260 does not get dulled or damaged. The positioning of the anchor tip 260 can be adjusted by having an anchor 255 with different base portion 257 thicknesses, as the anchor 255 can rotate until the base portion 257 of the anchor 255 contacts the base 245.
  • The base 245 may also have one or more suture holes 285 for suturing the port 130 to the human 105, in the event that the use of the applier 135 to attach the port 130 is not desired or allowable. A drawback of suturing is the additional time and effort required by the medical professional to secure the port 130 during surgery.
  • In some embodiments, the anchors 255 are simultaneously removable or reversible, allowing the anchors 255 to be detached from the bodily tissue. For example, the top portion 205 can be rotated in a counter-clockwise direction to remove the anchors 255 from the tissue. Specifically, to un-deploy the anchors 255, the cap 205 is rotated in a counter-clockwise direction and the teeth 230 are engaged with the teeth 280 to rotate the gear 275 and the anchor 255 in a clockwise direction causing the anchors 255 to move through the anchor opening 265 and out of the tissue. The anchor tip 260 may also move into the anchor opening 265.
  • In one embodiment, a plurality of anchors 255 includes four anchors that are evenly spaced apart around the base 245. Each anchor 255 may be referred to as being independent, which includes being a separate component or having separate operation from another anchor 255. Each anchor 255 includes a curved distal portion or anchor tip 260 which engages the bodily tissue and a pivotal proximal portion or body portion 257, which is rotatably connected to the base 245 of the port 130. In some embodiments, the pivotal proximal portion is substantially perpendicular with the curved distal portion, or more specifically, substantially perpendicular with a plane in which the curved distal portion rotates when the anchors are moved into the deployed position. In some embodiments, each anchor 255 may include a generally spiral distal portion and a straight proximal portion substantially perpendicular with the spiral distal portion.
  • The port 130 may further include a removable safety cap (not shown) to protect the medical professional's hands and fingers from accidental anchor sticks. The safety cap may mount to the bottom of the port 130 by a press-on fit. The color of the safety cap may be easily distinguishable from the color of the port 130.
  • The base 245 may be moveably attached to the top portion 205 by the reservoir 210. A stem 240 is attached to the reservoir 210 for injecting the fluid from the port 130 to the band 110. The stem 240 may include a strain relief element which locks into the housing 500 and protects the catheter 125 from folding, kinking, rotating, or torquing when the catheter 125 is connected to the reservoir 210. Further strain relief may be provided by a flexible sleeve made of a puncture resistance material. The flexible sleeve and the strain relief element provide protection against accidental needle punctures to the catheter 125.
  • Referring to FIG. 5, the disassembled perspective view showing the different parts of the port 130 of FIG. 2 discloses the inner ring 206, the septum 215, the top portion 205, the housing 500, the reservoir 210 and the stem 240, the base 245 and the related components and a radiopaque marker 520. The inner ring 206 may also include a titanium palpation ring. The housing 500 may also be referred to as a port housing. The housing 500 surrounds the port 130 and covers the components therein.
