1. A system for repairing an arterial aneurysm, the system comprising:
- a) a catheter delivery means; and
b) an arterial graft apparatus comprising;
i) a flexible, tubular sleeve having at least one axis therethrough and further comprising a first end, at least one opposite end located opposite said first end, an exterior portion and an interior portion;
ii) at least one exterior conduit surrounding the exterior portion of said sleeve, each of the at least one exterior conduits having an inlet port and an exhaust port;
iii) introduction means associated with the catheter delivery means and being in communication with each inlet port; and
iv) hardening means delivered through said introduction means for causing the arterial graft device to assume a rigid cylindrical configuration, the hardening means being a polymeric material;
whereby when the apparatus is delivered to an area of an artery having an aneurysm such that the sleeve is positioned at the aneurysm and hardening means is introduced, the conduits are caused to assume a rigid, expanded configuration which fits securely into the artery and is anchored thereto by pressure, causing the sleeve to be supported in an open condition for fluid flow therethrough, and causing the aneurysm to be repaired.
