Implantable injection port
First Claim
1. An implantable injection port for 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;
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;
an outer shell and an inner base shaft coupled to the base, the cap being guided by and positioned between the shell and the base shaft; and
a septum positioned in the base shaft.

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.
