The prosthesis for insertion into a blood or other vessel, through the skin, has a support body (11) covered by a cuff (12) which can expand from the small insertion dimensions to the larger dimensions after implantation. At least one feed tube (14) is connected to the cuff for the delivery of medication or other substances, opening into the intermediate zone (19) formed by the walls between the cuff and the implantation zone, when implanted. The outer surface of the cuff (12) has a thin layer of applied silicone oil, to prevent adhesion. |
