Abstract
Abstract An implantable connector (1) to replace a portion of a patient's body conduit and to connect this conduit to a vascular implant device in order to provide access to the body conduit externally from the body, includes a tubular member (3) having a bulbous portion (5) provided with a side port (7) for connection to the vascular implant device. An implant device (31) has a passageway (33), an anchor (35) for establishing a biological anchor and a grafting mesh (39) annularly disposed about, and spaced apart from, the exterior of the passageway. The passageway, anchor means, and grafting mesh are all formed from either pyrolytic carbon disposed on a graphite substrate or vitreous carbon. The implant device (71) may have a passageway, the inlet section of which is inclined at 45 DEG -75 DEG to its outlet section. <IMAGE>
