An intraluminal grafting stent that includes a collapsible tube member having a first end and a second end. An outer wall and an inner wall extend between the ends. A first end wall and a second end wall extend between the outer wall and the inner wall. The outer, inner, first end and second end wall form a chamber. A permeable film layer 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. A composite material is positioned in a chamber between the inner wall and the permeable film layer. An opening is positioned in one of the end walls to allow the introduction of a reagent into the defined space. The reagent reacts with the composite material to cause the composite material to harden after the intraluminal grafting stent has been positioned in a blood vessel. The present invention is further directed to a method for implanting the intraluminal grafting stent in a blood vessel. Using a balloon catheter. |
