Thoracic aneurysm repair prosthesis and system

摘要

A system for repairing an aneurysm in a large blood vessel comprises a first prosthesis (10a), a second prosthesis (10b), and at least one third prosthesis (11a,11b) . The first prosthesis comprises a stent (12) and a gasket (30) for sealing the system. The second prosthesis (10b) comprises a stent and a gasket (30) material for anchoring a distal portion of the system. The third prosthesis (11a,11b) comprises a stent and a graft material (60) for establishing a fluid flow path therethrough. The first prosthesis, the second prosthesis, and the third prosthesis form at least one fluid flow path through the aneurysm.
