<p>This invention is an intraluminal graft, method and apparatus for installing an intraluminal graft in relation to a bifurcation of a trunk vessel into two branch vessels to bypass an aneurysm defect or injury, wherein the intraluminal graft is formed to two cooperating graft prostheses (110, 140). The first graft prosthesis (110) is formed by a self-expanding, collapsible stent that may be collapsed under restraint, positioned to bridge the bifurcation, allowed to expand to resemble trousers with the waist opening (114) facing the lumen of trunk vessel, the legs (126, 128) fitting within the branch vessels and defining a first graft lumen therebetween. The second graft prosthesis (140) is formed of a tubular member of sheet material that may be collapsed under restraint, advanced through the first graft lumen, and then allowed to self-expand to be seated in the waist opening against the trunk vessel wall.</p> |
