1. A vascular graft device comprising:
- a) a flexible, tubular sleeve configuration having at least one axis therethrough and further comprising a first end, at least one opposite end and an exterior portion;
b) at least one peripheral conduit surrounding said sleeve, each said at least one peripheral conduit having an inlet port;
c) delivery means connected to at least one conduit at its inlet port, said delivery means being in association with a hardening means;
whereby when the device is delivered to an area of a vessel having an aneurysm such that the device is positioned at the aneurysm and the hardening means is delivered, the hardening means causes the at least one peripheral 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.

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.

11. A vascular graft device comprising:
-
a) a flexible tubular sleeve configuration having at least one axis therethrough and further comprising a first end, at least one second end, an interior portion and an exterior portion;
b) a peripheral conduit surrounding each of said ends, each peripheral conduit having at least one entrance port; and
c) introduction means in communication with the port of each end tube for introduction of a hardening means;
whereby when the device 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 peripheral conduits are caused to assume an expanded, rigid 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.

12. An apparatus for repairing an arterial aneurysm, the apparatus comprising:
-
a) a catheter delivery means; and
b) an arterial graft device comprising;
i) a flexible, tubular sleeve configuration having at least one axis therethrough and further comprising a first end, at least one opposite end, and exterior and interior portions;
ii) a peripheral conduit surrounding the sleeve and having at least one port;
iii) introduction means associated with the catheter delivery means and being 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. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
