Intraluminal stenting graft
First Claim
1. An intraluminal stenting graft for implantation in a blood vessel, comprising:
- a collapsible tube member having a first end and a second end, an outer layer and an inner layer extending between said ends, said outer layer being joined along a plurality of longitudinally extending lines to said inner layer to form a plurality of cylinders between said inner layer and said outer layer extending longitudinally between said first end and said second end, said cylinders, when expanded, providing structural support to said tube member, said tube member including means for introducing an absorbate therein; and
an absorbent positioned in at least one of said cylinders, whereby when said absorbate is introduced to said plurality of cylinders and said absorbent, said absorbent absorbs said absorbate and increases in volume to support said tube member in said blood vessel.

Abstract
An intraluminal stenting graft for implantation in a blood vessel including a collapsible tube member having a first end and a second end. The tube member further includes an outer layer and an inner layer extending between the ends. The outer layer is joined to the inner layer to form a plurality of cylinders extending longitudinally between the first end and the second end. The cylinders provide structural support to the tube member. An absorbent is positioned in at least one of the cylinders. When an absorbate is introduced to the plurality of cylinders and the absorbent, the absorbent absorbs the absorbate. The absorbent increases in volume as a result of such absorption to support the collapsible tube member at the site of implantation of the intraluminal stenting graft in a blood vessel.
