Abstract
An intraluminal graft and 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 of two cooperating graft prostheses. The first graft prosthesis is formed of a flexible tubular member having leg openings and a side, waist opening defined by self-expanding, collapsible stents that may be collapsed under restraint and positioned to bridge the bifurcation and allowed to expand to resemble trousers with the waist opening facing the lumen of trunk vessel and the legs fitting within the branch vessels and defining a first graft lumen therebetween. The second graft prosthesis is formed of a tubular member of sheet material that may be collapsed under restraint and advanced through the first graft lumen and then allowed to self-expand to be seated in the waist opening and against the trunk vessel wall.
