Abstract
An endovascular prosthesis (10) includes a first end (16) a furcated second end (18), and an anchoring means (20). The first end has a longitudinally extending central lumen (32) and means (40) for laterally supporting the first end. The furcated second end (18) includes at least two branches (64) that extend from an intersection of the furcated second end. Each of the branches (64) includes a longitudinal support means (84) and a branch lumen (78) in fluid communication with the central lumen (32) of the first end (16). The anchoring means (20) secures the first end (18) within a vasculature.

68. A method of constructing an endovascular prosthesis with at least three outflow branches, said method comprising the steps of:
-
providing at least two grafts, each of said at least two grafts having a first end, a second end, and a lumen extending longitudinally between the first end and the second end, said first end of each of said at least two grafts including means for laterally supporting said first end, said second end of each of said at least two grafts including means for longitudinally supporting said second end;
deforming said first end of each of said at least two grafts to produce a connection surface on each of said at least two grafts; and
joining said connection surfaces of each of said at least two grafts to form an endovascular prosthesis with at least two outflow lumens that are in fluid communication with a central lumen.

71. A method of treating an abdominal aortic aneurysm that extends from a portion of the aorta caudal the renal arteries to the aorta iliac junction, said method comprising the steps of:
-
providing a first stent-graft assembly, said first stent-graft assembly including a first end, a furcated second end, and an anchoring means for securing said first end within the aorta, said first end having a longitudinally extending central lumen and a means for laterally supporting said first end, said furcated second end including four branches that extend from an intersection of said furcated second end, each of said branches including a longitudinal support means and a branch lumen in fluid communication with said central lumen of said first end;
deploying said first stent-graft assembly within the aorta so that the anchoring means extends across the renal artery junction of the aorta and the furcated second end extends into the abdominal aortic aneurysm;
providing four outflow limbs, said four outflow limbs each having a first end and a second end, and a lumen extending between said first end and second end; and
connecting said first ends of each of said outflow limbs to said four branches of said furcated second end of said stent-graft assembly and said second ends of each of said outflow limbs to branch arteries of the aorta to allow blood flow from said first stent-graft through said outflow limbs to said branch arteries. - View Dependent Claims (72, 73, 74, 75)
