1. A method of deploying an implantable injection port, comprising:
- preparing an injection port for implant, the port including;
a housing defining a periphery around a vertical axis and having an upper face and a lower face opposite the upper face;
a septum within the housing open to the upper face and capable of penetration by a needle;
a space below the septum and within the housing defining a fluid reservoir; and
a plurality of sharp-tipped fasteners rotatably mounted to the housing to rotate from an undeployed position not projecting below the lower face of the port to a deployed position projecting below the lower face of the port;
covering the injection port with a distal cover of a delivery system having a proximal handle terminating in a manual actuator;
positioning the injection port lower surface on the bodily tissue;
activating the manual actuator such that the sharp-tipped fasteners rotate from their undeployed positions to their deployed positions to secure the injection port in bodily tissue; and
,removing the delivery system from the secured injection port.

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 fit 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.

preparing an injection port for implant, the port including; a housing defining a periphery around a vertical axis and having an upper face and a lower face opposite the upper face; a septum within the housing open to the upper face and capable of penetration by a needle; a space below the septum and within the housing defining a fluid reservoir; and a plurality of sharp-tipped fasteners incorporated into the housing and mounted to move from an undeployed position not projecting below the lower face of the port to a deployed position projecting below the lower face of the port; covering the injection port with a distal cover of a delivery system having a proximal handle terminating in a manual actuator; positioning the injection port lower surface on the bodily tissue; activating the delivery system such that the sharp-tipped fasteners move from their undeployed positions to their deployed positions; reversing the movement of the sharp-tipped fasteners so that they resume their undeployed positions; repositioning the injection port; activating the delivery system again such that the sharp-tipped fasteners move from their undeployed positions to their deployed positions to secure the injection port in bodily tissue; and
,removing the delivery system from the secured injection port. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

preparing an injection port for implant, the port including; a housing defining a periphery around a vertical axis and having an upper face and a lower face opposite the upper face; a septum within the housing open to the upper face and capable of penetration by a needle; a space below the septum and within the housing defining a fluid reservoir; and a plurality of sharp-tipped fasteners incorporated into the housing and mounted to move from an undeployed position not projecting below the lower face of the port to a deployed position projecting below the lower face of the port; covering the injection port with a distal cover of a delivery system, the distal cover defining a recess that receives and engages 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 delivery system having a proximal shaft extending upward from the distal cover at an angle to the vertical and terminating in a manual actuator; positioning the injection port lower surface on the bodily tissue; activating the manual actuator such that the sharp-tipped fasteners move from their undeployed positions to their deployed positions to secure the injection port in bodily tissue; and
,removing the delivery system from the secured injection port. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
