Implantable access port system
First Claim
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;
a gear coupled to the base and rotatable about a first axis of the gear, the gear having a plurality of gear teeth;
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.

Abstract
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.

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. - View Dependent Claims (14, 15, 16)

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. - View Dependent Claims (19, 20, 21)
