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 and having at least one port, the at least one exterior conduit being adjacent to the exterior portion of the sleeve, but not coextensive with the sleeve;
iii) introduction means in communication with each at least one port; and
iv) hardening means delivered through said introduction means for causing the arterial graft device to assume a rigid cylindrical configuration;
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.

Abstract
Percutaneous treatment of aortic aneurysms and like vascular anomalies by an apparatus and method wherein the apparatus is delivered via catheter and comprises a sleeve with at least one peripheral conduit which is caused to assume an expanded, rigid configuration by the introduction of a chemical or mechanical hardening means, whereby the sleeve is caused to assume an open cylindrical configuration for fluid flow therethrough.

12. A vascular graft system comprising:
-
a) 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, and an exterior portion; b) at least one exterior conduit surrounding the exterior portion of said sleeve, each said at least one exterior conduit having an inlet port, the at least one exterior conduit being adjacent to the exterior portion of the sleeve, but not coextensive with the sleeve; c) delivery means removably connected to the at least one exterior conduit at its inlet port, said delivery means being in association with a hardening means, said hardening means comprising at least one wire for insertion into and extension through the introduction means into an exterior conduit; whereby when the sleeve is delivered to an implant site at an area of a vessel having an aneurysm such that the apparatus is positioned at the aneurysm and the hardening means is delivered, the hardening means causes the at least one exterior conduit to assume an expanded, rigid configuration which fits securely into the vessel and is anchored thereto by pressure, causing the sleeve to be supported in an open condition for fluid flow therethrough. - View Dependent Claims (13, 14, 15)
