Endovascular graft
First Claim
1. An implantable device, comprising:
- a frame structure of biocompatible graft material having first and second opposed open ends, said first opposed open end having a longitudinal axis and a neck portion disposed directly at a terminal portion of said first opposed open end;
a non-inflatable expansion member generally coextensive with the longitudinal axis of said first opposed open end and securably disposed at the neck portion of said frame structure;
an inflatable structure disposed over at least a first portion of said frame structure near said first opposed open end, wherein the inflatable structure is longitudinally spaced apart from the non-inflatable expansion member; and
a fluid for inflating the inflatable structure;
wherein the inflatable structure is inflatable with the inflation fluid to provide an inflated state such that the inflated state conforms to the shape of a bodily lumen.

Abstract
An endovascular graft, which is configured to conform to the morphology of a vessel to be treated, includes a tubular ePTFE structure; an inflatable ePTFE structure disposed over at least a portion of the ePTFE tubular structure; and an injection port in fluid communication with the inflatable ePTFE structure for inflation of the inflatable ePTFE structure with an inflation medium. The inflatable ePTFE structure may be longitudinally disposed over the tubular ePTFE structure. The ePTFE structure may be a bifurcated structure having first and second bifurcated tubular structures, where the inflatable ePTFE structure is disposed over at least a portion of the first and second bifurcated tubular structures.

13. An implantable device, comprising:
-
a frame structure comprising biocompatible graft material having first and second opposed open ends and a metallic reinforcement member, said first opposed open end having a longitudinal axis and a neck portion disposed directly at a terminal portion of said first opposed open end; an inflatable structure disposed over at least a first portion of said frame structure near said first opposed open end; and a fluid for inflating the inflatable structure; wherein the metallic reinforcement member is securably disposed at the neck portion of said frame structure, the metallic reinforcement member being longitudinally spaced apart from the inflatable structure; and wherein the inflatable structure is inflatable with the inflation fluid to provide an inflated state such that the inflated state conforms to the shape of a bodily lumen. - View Dependent Claims (14, 15, 16, 17, 18, 19)
