INTRALUMINAL STENTING GRAFT

摘要

This invention is an intraluminal stenting graft (10) for implantation in a blood vessel and a method for making same wherein the intraluminal stenting graft includes a collapsible tube member (12) having a first end (14) and a second end (16). An outer layer (18) and inner layer (20) extend between the ends (14, 16). The outer layer (18) is more flexible than the inner layer (20). The outer layer (18) is joined to the inner layer (20) to form a plurality of cylinders (30) longitudinally extending between the first end (14) and the second end (16). The method of the present invention including the steps of placing a first layer of material (70) on a shaped surface; maintaining the second layer (80) on said shaped surface by use of reverse pressure; moving the second layer to the first layer; joining the second layer to the first layer to form a plurality of longitudinally extending cylinders (30); and shaping the first and second layers to form a tube member.
