Patent ID: 7682383

Claim:
Apparatus for repairing an aneurysm, comprising a device for deployment within the aneurysm, said device comprising an inner graft tube and an inflatable outer balloon over said inner graft tube, said inner graft tube being a single layer tube having an inner surface circumscribing a longitudinal passage through said tube and having an outer surface, said outer balloon having an inner wall formed by said tube and having an outer wall extending circumferentially around said tube and extending longitudinally along said tube, said outer wall having opposed ends attached to said outer surface along the circumference of said tube and at longitudinally spaced locations along said tube to enclose an interior of said balloon between said outer wall and said tube with said outer surface of said tube being disposed in said interior, said inner graft tube having an unexpanded condition and said inflatable outer balloon having an uninflated condition allowing deployment of said device in an artery at the location of an aneurysm, said inner graft tube being expandable within the artery to an expanded condition to contact the wall of the artery above and below the aneurysm to form a seal with the wall of the artery above and below the aneurysm, said outer balloon being inflatable within the aneurysm to an inflated condition with a rapidly settable substance supplied between said outer wall and said tube, said outer balloon in said inflated condition filling the aneurysm to support said device and to maintain said inner graft tube in said expanded condition; and an inflatable deployment balloon having an uninflated condition to fit within said longitudinal passage of said inner graft tube in said unexpanded condition, said deployment balloon being inflatable within said inner graft tube to expand said inner graft tube from said unexpanded condition to said expanded condition within the artery and to maintain said inner graft tube in said expanded condition within the artery during inflation of said outer balloon with the settable substance, said deployment balloon being removable from said inner graft tube upon setting of the settable substance, whereby said device remains in the artery with said inner graft tube in said expanded condition and said outer balloon in said inflated condition.
