Claim:
A prosthesis assembly for a blood vessel or hollow body organ comprising, a trunk including a prosthetic material having an interior including a seam joining opposing surfaces of the prosthetic material together to form an internal septum sized and configured to define, within at least a portion of the trunk interior, a multi-lumen flow channel configuration comprising a trunk lumen, at least a first interior lumen and a truncated second interior lumen that is shorter than the first interior lumen, wherein the first interior lumen and the truncate second interior lumen extend along the internal septum, at least two stent structures carried in a spaced apart relationship along each of the first interior lumen and the truncated second interior lumen to support the respective interior lumen, the septum being formed separate from the stent structures, the stent structures in one of the interior lumens being staggered in position with respect to the stent structures in the other interior lumen such that the stent structures in the first interior lumen do not overlap or align with the stent structures in the truncated second interior lumen, and a lumen extension component sized and configured to be fitted within at least one of the first and truncated second interior lumens to define an extension of the at least one interior lumen.
