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.
Claims22
An implantable injection port and protective fixture system, comprising:
- an implantable injection port having a housing defining generally an upper face, a lower face, and a peripheral outer wall, a septum held within the housing and open to the upper face, 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 plurality of fasteners incorporated into the housing to enable a user to attach the port to tissue without sutures, the fasteners each having an undeployed position and a deployed position, the deployed position extending below the lower face of the port opposite the upper face;
- and
- a protective fixture adapted to removably attach over the lower face of the housing and cover the fasteners.
An implantable injection port and protective fixture system, comprising:
- (a) implantable injection port having a housing defining generally an upper face, a lower face, and a peripheral outer wall, a septum held within the housing and open to the upper face, 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,
- (b) an attachment mechanism comprising at least one fastener for attaching the injection port to a body, the fastener having a deployed position that extends from a distal end of the injection port, and an undeployed position proximal to the distal end of the injection port;
- and
- (c) a loading fixture covering the fastener and removably attached to the distal end of the injection port to protect a user from accidental contact with the fastener.
