This invention is an intraluminal grafting stent (10) that includes a collapsible tube member (12) having a first end (14) and a second end (16). An outer wall (18) and an inner wall (20) extend between the ends. A first end wall (22) and a second end wall (24) extend between the outer wall and the inner wall. The outer, inner, first end and second end walls form a chamber (26). A permeable film layer (30) extends between the first end wall and the second end wall in the chamber. The film layer, outer wall, and end walls define a space (32). A composite material (34) is positioned in the chamber between the inner wall and the permeable film layer. An opening (40) is positioned in one of the end walls to allow for the introduction of a reagent (60) into the defined space. The reagent reacts with the composite material to cause the composite material to harden after the stent has been positioned in a blood vessel. |
