<p>This invention relates to an implant device. It is well known in the art that there are various methods for externalizing an internal vessel, or providing fluid communication from the vascular system to a cleansing source outside the body. In the former, the ulceration of the skin, and in the latter the trauma of connecting and reconnecting arteries and veins with tubes or needles have proved to be serious problems. The present invention seeks to do away with these problems by providing an implant device which connects to an implantable connector in order to provide access to the body conduit or vessel external from the body. The implant device has a passageway, which is either straight or curved at the outlet, an anchor means for establishing a biological anchor, and a grafting mesh annularly and longitudinally diposed about, and longitudinally spaced apart from, at least a portion of the exterior of said implant device whereby tissue is permitted to grow between the exterior of the device and the mesh. The passageway, anchor means and grafting mesh are formed from a material selected from the group comprising pyrolytic carbon disposed on a graphite substrate and vitreous carbon.</p> |
