Abstract:
An endoluminal prosthesis comprising:a tubular graft configured to sealingly engage an inner wall of a body lumen and comprising: a proximal portion comprising a trunk portion having a proximal opening, and a distal portion branched into a first branch portion and a second branch portion, each of the first and second branch portions having a distal opening, the trunk portion and the first and second branch portions forming a lumen for the flow of body fluids from the proximal opening through the distal openings of the first and second branch portions; and a valve located at least in part within the first branch portion, said valve comprising a first support member, a second support member and a section of graft material coupled to the first and second support members, wherein the first support member is coupled to the first branch portion within the first branch portion so that the first support member provides an opening in the first branch portion through which body fluids from the trunk portion may flow, and wherein the second support member has a first, closed position and a second, open position wherein in the first closed position a portion of the section of the graft material comprises a cover configured to prevent the flow of body fluids through the opening in the first branch portion, wherein the second support member is configured to hold the portion of the section of graft material in a position in which it is forms the cover, and wherein in the second, open position, the second support member is configured to hold the graft material in a position that permits the flow of body fluids through the opening in the first branch portion.
