Endovascular graft
First Claim
1. An endovascular graft comprising:
- a tubular ePTFE structure having a proximal and a distal end;
an inflatable ePTFE structure disposed over at least a first portion of the ePTFE tubular structure;
a self-expanding expansion member secured to a second portion of the proximal or the distal end of said tubular ePTFE structure and extending beyond the proximal or distal end of said tubular ePTFE structure, said second portion of the proximal or the distal end of said tubular ePTFE structure being disposed away from said first portion of said inflatable ePTFE structure; and
an injection port in fluid communication with the inflatable ePTFE structure for inflation of the inflatable ePTFE structure with an inflation medium.

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.

16. An endovascular graft comprising:
-
a tubular ePTFE structure having a proximal and a distal end; an inflatable ePTFE structure disposed over at least a portion of the ePTFE tubular structure; at least one annular inflatable cuff disposed at the proximal or distal end of said tubular ePTFE structure; a self-expanding expansion member having a proximal end and a distal end, the distal end of the expansion member being secured to the proximal or distal end of said tubular ePTFE structure, the proximal end of the expansion member extending beyond the proximal or distal end of said tubular ePTFE structure; and an injection port in fluid communication with the inflatable ePTFE structure for inflation of the inflatable ePTFE structure with an inflation medium; wherein the expansion member comprises a plurality of outwardly directed protuberances. - View Dependent Claims (17, 18)
