Abstract
A venous polytetrafluoroethylene (PTFE) graft with integral access port system. The graft may have one, two, or more ports, which then exits the skin. The prosthesis may be made of fluoropolymer tubing fabricated in such a way as to involve several performance features. The graft may have holes for suturing, anchoring, or bio-integration to the artery. The ports have natural acting restrictions or valves at the graft juncture, throughout the implanted part body of the device and at the exit site. The ports are also naturally self-purging. A port may also incorporate a redundant hermetic hemostatic valve and closure system at the exit site.
