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.
Claims6
A collapsible stent graft, which comprises a collapsible tubular member for lining a blood vessel and an inflatable member extending around the tubular member and attached thereto, whereby inflation of the inflatable member expands the tubular member from a collapsed state to an expanded state;
- wherein an outer layer is provided around the tubular member and is fused or adhered thereto so as to provide said inflatable member,
- wherein said inflatable member comprises a plurality of interconnected concentric and cylindrical tubules attached to and encasing a circumference of the tubular member,
- wherein the inner tubular member is formed of expanded polytetrafluoroethylene,
- wherein the outer layer is formed of expanded polytetrafluoroethylene, and wherein the collapsible stent graft is capable of being detached from a delivery system and permanently placed within the blood vessel.
