Abstract
Abstract 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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
186 words
An intraluminal grafting stent for use in a blood vessel comprising, in combination: a collapsible tube member having a first end and a second end, an outer wall and an inner wall extending between said ends, a first end wall and a second end wall extending between said outer wall and an inner wall, said outer, inner, first end and second end walls forming a chamber; a permeable film layer extending between said first end wall and said second end wall in said chamber, said film layer, said outer wall and said end walls defining a space; a composite material positioned in said chamber between said inner wall and said permeable film layer; an opening in one of said end walls for introducing a reagent into said defined space; whereby when said grafting stent is inserted in a blood vessel, said collapsible tube member is expanded by an expandable catheter, a reagent is introduced through said opening, said reagent travels through said permeable film layer, said composite material reacts with said reagent causing said material to harden to allow said graft to support said blood vessel.
Claim 2
Dependent Claim
186 words
An intraluminal grafting stent for use in a blood vessel comprising, in combination: a collapsible tube member having a first end and a second end, an outer wall and an inner wall extending between said ends, a first end wall and a second end wall extending between said outer wall and an inner wall, said outer, inner, first end and second end walls forming a chamber; a permeable film layer extending between said first end wall and said second end wall in said chamber, said film layer, said outer wall and said end walls defining a space; a composite material positioned in said chamber between said inner wall and said permeable film layer; an opening in one of said end walls for introducing a reagent into said defined space; whereby when said grafting stent is inserted in a blood vessel, said collapsible tube member is expanded by an expandable catheter, a reagent is introduced through said opening, said reagent travels through said permeable film layer, said composite material reacts with said reagent causing said material to harden to allow said graft to support said blood vessel.
Claim 3
Dependent Claim

Claim 8
Independent Claim
181 words
A method for implanting an intraluminal grafting stent in a blood vessel comprising the steps of: (a) placing an expandable catheter in an intraluminal grafting stent comprised of a collapsible tube member having a first end and a second end, an outer wall and an inner wall extending between said ends, a first end wall and a second end wall extending between said outer wall and said inner wall, said outer, inner, first end and second end walls forming a chamber, one of said end walls defining an opening, said chamber containing a composite material, said catheter being adjacent to said inner wall; (b) inserting said intraluminal grafting stent in a blood vessel by said catheter; (c) expanding said catheter to cause said collapsible tube member to expand at a site in said blood vessel where said grafting stent is to be implanted; (d ) introducing a reagent in said opening; (e) permitting said reagent to react with said composite material to cause said composite material to harden; (f) collapsing said catheter; and (g) removing said catheter from said blood vessel.
Claim 9
Independent Claim
181 words
A method for implanting an intraluminal grafting stent in a blood vessel comprising the steps of: (a) placing an expandable catheter in an intraluminal grafting stent comprised of a collapsible tube member having a first end and a second end, an outer wall and an inner wall extending between said ends, a first end wall and a second end wall extending between said outer wall and said inner wall, said outer, inner, first end and second end walls forming a chamber, one of said end walls defining an opening, said chamber containing a composite material, said catheter being adjacent to said inner wall; (b) inserting said intraluminal grafting stent in a blood vessel by said catheter; (c) expanding said catheter to cause said collapsible tube member to expand at a site in said blood vessel where said grafting stent is to be implanted; (d ) introducing a reagent in said opening; (e) permitting said reagent to react with said composite material to cause said composite material to harden; (f) collapsing said catheter; and (g) removing said catheter from said blood vessel.
