Implantable device fastening system
First Claim
1. An implantable injection port and delivery tool system, comprising:
- an implantable injection port comprising a base, a septum being capable of penetration by a needle above the base, a space below the septum defining a fluid reservoir, a plurality of fasteners pivotally connected to the base and movable between an undeployed position and a deployed position, and a first rotatable element connected to the base, the first rotatable element being structured and positioned to cause deployment of the plurality of fasteners upon rotation of the first rotatable element; and
a delivery tool for facilitating implantation of the injection port into soft tissue, the delivery tool comprising;
a second rotatable element configured to removably engage the first rotatable element, andan activation assembly effective to move the fasteners into the deployed position, the activation assembly having a transmission element operationally coupled to the second rotatable element.

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.

15. An implantable injection port and deployment tool system, comprising:
-
an implantable injection port comprising a generally cylindrical housing, a septum retained by the housing and capable of penetration by a needle, a space below the septum along a central axis of the generally cylindrical housing defining a fluid reservoir, a plurality of soft tissue fasteners arrayed circumferentially around the central axis and pivotally connected to the housing to rotate about radial axes, and a first rotatable element mounted to the housing to rotate about the central axis, the first rotatable element being structured and positioned to cause deployment of the plurality of fasteners upon rotation of the first rotatable element; and a deployment tool having a distal cover defining a recess that receives the implantable injection port therein, the cover and recess being oriented to extend down over the port generally vertically along the central axis, the tool having a second rotatable element in the distal cover configured to removably engage the first rotatable element and deploy the fasteners. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)
