Abstract

Expandable intraluminal prostheses for the treatment of aneurysmal disease or occlusive disease at a bifurcation of a vessel, duct, or lumen, e.g, disease at the aorto-iliac bifurcation. Each prosthesis includes three expandable, sleeve sections which are arranged to be located in respective portions of the vessel, duct, or lumen contiguous with the bifurcation, and secured together in situ. The prosthesis for aorto-iliac aneurysmal disease includes a common, stent-supported sleeve section having an expandable outer balloon for engaging and trapping the thrombus in the aneurysmal space in the abdominal aorta, and a pair of stent-supported sleeve limb sections. The limb sections are connected to the common section to provide a passage for blood to flow through the prosthesis. One or more of the limb sections can also include a outer balloon for engaging the thrombus within its associated aneurysmal space. Sealing mesh is provided on the prosthesis to prevent the egress of emboli and to permanently secure it in place. The prosthesis for aorto-iliac occlusive disease is similar the prothesis for aneurysmal disease, except that the sections of the prosthesis do not include an outer balloon.
