Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
202 words
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.
Claim 2
Independent Claim
202 words
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.
Claim 3
Dependent Claim
19 words
The system of claim 1 wherein the polymeric material is introduced through the introduction means via an external source.
Claim 4
Dependent Claim
11 words
The of claim 1 wherein the external source is a syringe.
Claim 5
Dependent Claim
12 words
The system of claim 1 wherein the external source is a catheter.
Claim 6
Dependent Claim
40 words
The system of claim 1 wherein the sleeve is made of a nonbiodegradable, biocompatible polymeric material, and the hardening means comprises an activatable hardening material selected from the group consisting of one-part polymer systems, two-part polymer systems and self-expanding monomers.
Claim 7
Dependent Claim
44 words
The system of claim 5 wherein the hardening means further comprises a plurality of microspheres wherein the activatable hardening material is carried, said microspheres being constructed and arranged to release the activatable hardening material upon disruption, thereby allowing the activatable hardening material to harden.
Claim 8
Dependent Claim
51 words
The system of claim 6 wherein the activatable hardening material comprises a first component and a second component isolated from each other by and carried in said microspheres, said microspheres being constructed and arranged to release said first and second components upon disruption, thereby allowing the components to react and harden.
