Abstract:
1. A collapsible stent graft for lining a blood vessel comprising: a collapsible inner tubular member having a proximal and a distal end and comprising expanded PTFE; an outer sleeve layer co-extensive with the inner tubular member and having a proximal and a distal end and comprising PTFE and disposed around the inner tubular member, the distal end of the outer layer being fused to the distal end of the inner tubular member, the proximal end of the outer layer being fused to the proximal end of the inner tubular member, and the outer layer attached to the inner tubular member at localized attachment points so as to define an inflatable member extending around the inner tubular member in a plurality of turns and attached thereto, wherein the inflatable member is expandable by inflation so that the inflatable member expands the inner tubular member from a collapsed state to an expanded state; a metallic stent disposed at the distal or proximal end of the fused collapsible inner tubular member and the fused outer sleeve layer; an inflation tube integrally formed between the outer sleeve layer and the inner tubular member for inflating the inflatable member; and hooks disposed on the metallic stent, the hooks being distal from the inflatable member.
