Prostheses for aneurysmal and/or occlusive disease at a bifurcation in a vessel, duct, or lumen

Claim 1

A prosthesis for the treatment of aneurysmal disease adjacent a bifurcation in a vessel, duct, or lumen of a living being, a portion of the vessel, duct or lumen proximal to the bifurcation having an aneurysm in the wall thereof defining an aneurysmal space, the bifurcation comprising a pair of branches of the vessel, duct, or lumen, with each of the branches having an aneurysm in the wall thereof defining an aneurysmal space, said prosthesis being arranged for introduction into the body of a living being with a common portion located in the portion of the vessel, duct, or lumen at the site of an aneurysmal space, and a pair of portions located within respective ones of the branches of the bifurcation at the sites of the aneurysmal spaces in the branches, said prosthesis comprising a common sleeve, a pair of limb sleeves, sealing means, sleeve connecting means, anchoring means, and outer balloon means; (a) said common sleeve comprising an elongated tube having an open upper end and an open lower end defining a passageway therebetween for conveying a body fluid therethrough, said common sleeve being arranged to be fixedly secured to the interior of the vessel, duct, or lumen by said anchoring means, and with said upper and lower ends of said common sleeve being sealed to portions of the vessel, duct, or lumen on respective sides of the aneurysm therein by portions of said sealing means, (b) said outer balloon means being coupled to and dispose about said common sleeve and arranged to be filled with a filling material to fill the aneurysmal space within the vessel, duct, or lumen, and to preclude the egress of body material from between the outer balloon means and the interior of the vessel, duct, or lumen at the situs of the aneurysm, (c) said limb sleeves being arranged to be located within respective ones of the branches of the bifurcation, with each of said limb sleeves comprising an elongated tube having an open upper end and an open lower end defining a passageway therebetween for conveying the fluid therethrough, said upper open ends of each of said limb sleeves being arranged to be fixedly secured to said common sleeve by said sleeve securement means at a location within said open bottom end of said common sleeve, whereupon said passageway in said common sleeve is in fluid communication with said passageways in said limb sleeves, and with portions of said sealing means being interposed between said common sleeve and said limb sleeves adjacent said joint to preclude the egress of the fluid from said joint.
