METHODS OF IMPLANTING AN INJECTION PORT
First Claim
1. A method for implanting an injection port in tissue, comprising:
- preparing an injection port for implant, the port including;
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; and
a sharp-tipped fastener attached to the housing and mounted to move from an undeployed position 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; and
a disc that rotates about the vertical axis for pivoting the fastener from the undeployed position to the deployed position;
coupling the injection port to a distal end of a deployment tool having a manual actuator and a transmission connected thereto for rotating the disc;
inserting the distal end of the deployment tool with the injection port into a patient;
positioning the lower face of the port against tissue; and
operating the manual actuator to cause the sharp-tipped fastener to move from the undeployed position to the deployed position to pierce tissue and attach the port to the 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 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.

13. A method for implanting an injection port in tissue, comprising:
-
preparing an injection port for implant, the port including; a housing 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 plurality of curved hooks attached to the housing and distributed around a lower face of the port opposite the upper face, each hook mounted to pivot 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; and a disc that rotates about the vertical axis for simultaneously pivoting the hooks from their undeployed positions to their deployed positions; inserting the injection port into a patient; positioning the lower face of the port against tissue; and rotating the disc to cause the hooks to move from their undeployed positions to their deployed positions to pierce tissue and attach the port to the tissue without sutures. - View Dependent Claims (14, 15)

27. A method for implanting an injection port in tissue, comprising:
-
preparing an injection port for implant, the port including; 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 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; and a disc that rotates about the central axis for simultaneously pivoting the fasteners from their undeployed positions to their deployed positions; inserting the injection port into a patient; positioning the lower face of the port against tissue; and rotating the disc to cause the fasteners to move from their undeployed positions to their deployed positions to pierce tissue and attach the port to the tissue without sutures.
