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.

An intraluminal prosthesis for use in a blood vessel, e. g. , the abdominal aorta, at which an aneurysm defining an aneurysmal space is located. The prosthesis basically comprises an expandable sleeve, an outer balloon, a pair of sealing rings or a sealing cover, a pair of expandable anchoring stents, and plural expandable support stents. The sleeve is an elongated tubular member defining a passageway having a pair of open ends for conveying blood therethrough. The outer balloon is disposed about the sleeve and is arranged to be filled with a fluid, e. g. , a gel or saline, to cause it to extend outward to fill the aneurysmal space. The sleeve is arranged to be expanded and held in that state by the stents. The anchoring stents fixedly secure the prosthesis to the interior of the vessel, with the ends of the sleeve being sealed by the sealing rings or sealing cover to portions of the vessel on respective sides of the aneurysm to preclude the ingress of blood between the outer balloon and the interior of the vessel at the aneurysm, while the blood is conveyed through the passageway, and to preclude the egress of material, e. g. , an embolus, from between the outer balloon and the interior of the vessel at the situs of the aneurysm.

An endovascular graft for securement within a vessel, duct, or lumen of a living being. The graft comprises a tubular graft sleeve and a plurality of ring-like stents mounted on the outer surface of the sleeve. Anchoring projections are provided on the outer surface of the stents. The graft sleeve has a passageway extending therethrough, which when-the graft is located within the vessel, duct, or lumen serves to carry body fluid, e. g. , blood, through it in a single direction. This action produces a force on the tubular sleeve and the plural stents mounted thereon. The anchoring projections extend outward from the outer surface of the stents and are arranged for engagement with the interior of the wall of the vessel, duct, or lumen. The anchoring projections are preferentially oriented to include portions extending at an acute angle to the direction of the fluid flow to tightly engage the interior of the wall of the vessel, duct, or lumen under the force applied by the fluid flowing through the device.
