Abstract:
1. A stent tissue graft prosthesis comprising: a first expandable stent having a first distal stent end and a first proximal stent end, a tubular wall and a passage extending longitudinally therethrough, a tissue graft having the property of eversion upon placement in a blood vessel if not supported, the tissue graft having a distal tissue graft end and a proximal tissue graft end and disposed on said first stent, but not secured to said stent, and a tubular member having a distal tubular member end and a proximal tubular member end, a wall and a passage extending longitudinally therethrough, said tubular member being disposed over said tissue graft and around said first stent and retaining said tissue graft disposed on said first stent solely by compressive forces, wherein the compressive forces are provided at least by an outward expansion of the first stent, wherein, in a pre-implantation configuration, a most distal end of the first distal stent end is at least coincident with a most distal end of the distal tissue graft end and a most proximal end of the first proximal stent end is at least coincident with a most proximal end of the proximal tissue graft end and where during implantation and post-implantation of the prosthesis, the most distal tissue graft end and the most proximal tissue graft end remain substantially in the pre-implantation configuration such that the tissue graft does not evert or fold into the passage of the first expandable stent; and wherein the distal and the proximal tubular member ends are substantially coincident with the respective distal and proximal first stent ends.
