Implantable device fastening system and methods of use
First Claim
1. An implantable injection port and deployment tool system, comprising:
- an implantable injection port comprising a housing and a septum retained by the housing, one end of the septum forming an upper face of the port generally oriented in a plane perpendicular to a vertical axis, the septum being capable of penetration by a needle along the vertical axis, the port further including a space below the septum defining a fluid reservoir and an outlet conduit through the housing from the reservoir, wherein the port further includes a fastener incorporated into the housing to enable a user to attach the port to tissue without sutures, the fastener having an undeployed position and a deployed position, the deployed position extending below a lower face of the port opposite the upper face; and
a deployment tool having a proximal shaft and a distal cover defining a recess that receives the port therein such that the lower face of the port is exposed, the cover and recess being oriented to extend down over the port generally vertically, the proximal shaft extending upward from the distal cover at an angle to the vertical and having a proximal manual actuator, the tool including a transmission in the shaft for transmitting movement of the actuator through elements in the shaft to the port for moving the fastener from its undeployed position to its deployed position and anchoring the port to tissue.

Abstract
A surgical fastening system for implantable devices is disclosed. The implantable device may contain a plurality of fasteners in pre-deployment position, may have a housing fitted over or around it which contains a plurality of fasteners in pre-deployment position, or may be a part of a two-part system into which it fits. Accordingly, the present invention also encompasses a deployment system or tool that optionally positions the implantable device, and which causes the fasteners to move into post-deployment position. The fasteners may be staples, metal loops, coils, springs or hooks formed of biocompatible materials, including shape memory alloys such as NiTi.
