1. An implantable injection port, comprising:
- a housing defining a periphery and having an upper face generally oriented in a plane perpendicular to a vertical axis;
a septum within the housing open to the upper face and capable of penetration by a needle along the vertical axis;
a space below the septum defining a fluid reservoir;
a tubing connector extending out of the housing from the periphery in fluid communication with the reservoir; and
a sharp-tipped fastener attached to the housing and mounted to pivot from an undeployed position within the housing periphery and not projecting below a lower face of the port opposite the upper face to a deployed position projecting below the lower face of the port to pierce tissue and enable a user to attach the port to tissue without sutures.

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.

13. An implantable injection port, comprising:
-
a housing having a generally circular periphery defining a central axis and an upper face; a septum within the housing open to the upper face and capable of penetration by a needle along the central axis; a space below the septum defining a fluid reservoir; a tubing connector extending radially out of the housing in fluid communication with the reservoir; and a plurality of curved metal fasteners attached to the housing and distributed circumferentially around a lower face of the port opposite the upper face, each fastener mounted to pivot about an axis that is generally radially oriented outward from the central axis from an undeployed position not projecting below the lower face of the housing to a deployed position projecting below the lower face of the housing to pierce tissue and enable a user to attach the port to tissue without sutures. - View Dependent Claims (14, 15, 16)
