Implantable access port system
View Patent ↗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.
1. An implantable injection port for use with a gastric band for treating obesity and for attaching to a tissue of a patient, the implantable injection port comprising:
a base having an anchor opening;

an anchor coupled to the gear, wherein the anchor has an attachment end coupled to the gear and a free end that is curved; 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 being rotatable about a second axis transverse to the first axis 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.
2. The implantable injection port of claim 1 , wherein the anchor free end is configured in the shape of a hook.
3. The implantable injection port of claim 2 , wherein the anchor has a flat surface adjacent to the attachment end that is used to stop the anchor from rotating beyond a predetermined position.
4. The implantable injection port of claim 1 , wherein the anchor is formed in the shape of a spiral and has a pointed end.
5. The implantable injection port of claim 1 , wherein the top portion has a center opening and an outer portion surrounding the center opening, the outer portion having one or more fittings.
6. The implantable injection port of claim 5 , further comprising a septum positioned within the center opening of the top portion and made of a self sealing needle penetrable material.
7. The implantable injection port of claim 6 , further comprising a reservoir positioned underneath the septum and between the top portion and the base for holding fluid.
8. The implantable injection port of claim 7 , further comprising a stem extending outward from the reservoir and a flange connected to the base and having a first end and a second end, the stem being movable along the flange from the first end to the second end.
9. The implantable injection port of claim 8 , wherein the anchor is in a deployed position when the stem is positioned at the first end of the flange and the anchor is in an undeployed position when the stem is positioned at the second end of the flange.
10. The implantable injection port of claim 9 , wherein the flange has a plurality of protrusions to lock the stem in place.
11. The implantable injection port of claim 5 , further comprising an actuation device having a handle and a port interface that attaches to and detaches from the one or more fittings to rotate the top portion.
12. The implantable injection port of claim 1 , wherein the anchor is constructed to rotate about the first axis with the gear.
13. An implantable injection port system for use with a gastric band for treating obesity and for attaching to a tissue of a patient, the implantable injection port system comprising:
a catheter having a first end and a second end;
a gastric band attached to the first end of the catheter; and
a port attached to the second end of the catheter, the port comprising:
a top portion having top and bottom surfaces and top teeth protruding from the bottom surface, a septum, and one or more fittings on the top surface,
a base spaced apart from the top portion,
a gear attached to the base and rotatable about a first axis of the gear, the gear having a plurality of bottom teeth that interact with the top teeth so that rotation of the top portion about a second axis transverse to the first axis causes rotation of the gear, and
an anchor attached to the gear, wherein rotation of the top portion causes rotation of the gear causing the anchor to move into and out of bodily tissue.
14. The implantable injection port system of claim 13 , wherein the port comprises an implantable access port.
15. The implantable injection port system of claim 13 , wherein the gastric band and the port are placed subcutaneously inside a patient.
16. The implantable injection port system of claim 13 , further comprising an applier configured to rotate the top portion.
17. An implantable injection port for use with a gastric band for treating obesity and for attaching to a tissue of a patient, the implantable injection port comprising:
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 rotatable about the central axis with 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 being 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.
18. An applier apparatus comprising:
a proximal end having a handle to be held by a medical professional or attached to a gripping device for rotating the handle;
a shaft attached to the handle, wherein rotation of the handle rotates the shaft; and
a distal end having a driver configured to mate with a fitting on a port to secure the port to a patient,
wherein the port comprises:
a top portion having an open center portion and a plurality of top teeth,
a base having an anchor opening,
a cylindrical port positioned between the top portion and the base,
a gear coupled to the base and having teeth that engage with the plurality of top teeth, and
an anchor attached to the gear, the top portion being rotatable causing rotation of the anchor about an axis of rotation of the gear such that the anchor passes through the anchor opening, the rotation of the gear causing rotation of the anchor into and out of bodily tissue.
19. The apparatus of claim 18 , wherein the applier comprises a compression spring around the shaft.
20. The apparatus of claim 19 , wherein the applier comprises a sleeve surrounding the compression spring.
21. The apparatus of claim 18 , wherein the anchor is formed in the shape of a cork screw.
