IMPLANTABLE INJECTION PORT
First Claim
1. An implantable injection port for use in conjunction with a gastric band and for attaching to bodily tissue, the implantable injection port comprising:
- a base having a first opening;
a cap having a handle, the cap moveable between an undeployed position and a deployed position using the handle, the cap spaced apart from the base when in the deployed position; and
a first anchor configured to be positioned in the first opening of the base, the first anchor having a cavity, a hole, an inner shaft, and an anchor wire, the inner shaft coupled to the cap such that moving the cap from the undeployed position to the deployed position causes a portion of the anchor wire to move through the hole to be positioned outside the cavity and moving the cap from the deployed position to the undeployed position causes a portion of the anchor wire to move through the hole to be positioned inside the cavity.

Abstract
An implantable injection port facilitates filling and/or draining an inflatable portion of a gastric band. In an embodiment, the port comprises a movable cap that causes anchor wires to extend from anchor devices in order to implant the injection port in the tissue of a patient. In another embodiment, the port comprises a handle that rotates to implant curved anchors into the tissue of a patient. In yet another embodiment, a cap is configured to move towards a base of the port in order to cause the curved anchors to rotate into the tissue of a patient. The cap may also rotate with respect to the base in order to lock the cap and the anchors in position. Further, surfaces of the injection port may be textured to increase adhesiveness to the patient'"'"'s tissue during installation and to facilitate simpler installation.

15. An implantable injection port for use in conjunction with a gastric band and for attaching to bodily tissue, the implantable injection port comprising:
-
a body having a first opening; a handle attached to the body, the handle moveable between a detached position and an attached position; and a first anchor device configured to be positioned in the first opening of the body, the first anchor device attached to the handle such that moving the handle from the detached position to the attached position causes a portion of the first anchor device to move through the first opening to be positioned outside the body and moving the handle from the attached position to the detached position causes a portion of the first anchor device to move through the first opening to be positioned inside the body. - View Dependent Claims (16, 17, 18, 19)

20. An implantable injection port, comprising:
-
a base; a curved anchor attached to a handle rotatably attached to the base, and when the handle is rotated, the curved anchor moves to an implanted position; and a quick-connect and strain relief fitting coupled to a reservoir disposed in the base. - View Dependent Claims (21, 22, 23, 24, 25, 26)

27. An implantable injection port for use in conjunction with a gastric band and for attaching to bodily tissue, the implantable injection port comprising:
-
a cap; a base coupled to the cap, the base having a first textured surface providing adhesiveness between the base and a contact surface; and a hook rotatably disposed within the base, and when the cap moves towards the base, the hook moves to an implanted position. - View Dependent Claims (28, 29, 30, 31)

32. An implantable injection port comprising:
-
a cap having an engagement surface; a base that nests within the cap and comprises a slot; an internal ring attached to the base; a curved anchor rotatably connected to the internal ring, wherein the curved anchor moves through the slot from an undeployed position to a deployed position when the cap moves toward the base to facilitate implanting the injection port in tissue; and a locking mechanism in the cap, wherein rotating the cap with respect to the base causes the locking mechanism to engage the curved anchor to lock the curved anchor in place and to prevent the cap from moving with respect to the base. - View Dependent Claims (33)
