Abstract:
1. A vascular prosthesis provided with branch means, for connecting a branch vessel to a vascular prosthesis arranged in a main blood vessel, said vascular prosthesis comprising a hollow tubular member, and said branch means comprising: a internal body inside said tubular member having a flange-shaped portion adjacent an inner wall of said tubular member and comprising a rigid hollow stem and at least one rigid barb member, said stem and said at least one barb member protruding from said flange-shaped portion and penetrating through said wall of said tubular body, in which said stem comprises a hollow channel opening at a free distal side of said stem external of said wall of said tubular member and opening at a proximal side of said stem inside said tubular body; and a disc-shaped external body registering with said flange-shaped portion at a side of said wall of said tubular member opposite said flange-shaped portion of said internal body, said disc-shaped external body having a bore, said stem extending through said bore, and having a circumferentially extending body portion which receives a free end of said at least one barb member to engage into a firm mutual connection with said internal body, wherein, during use, a wall of said main vessel and said wall of said tubular member are jointly clamped between said flange shaped portion of said internal body and said circumferentially extending body portion of said external body, and wherein, during use, said stem extends inside said branch vessel thereby creating an open fluid connection between said main vessel and said branch vessel through said channel.
