Abstract
Abstract A system and method for exclusion of an aneurysm of an aortic arch region using a graft delivery system capable of maneuvering around an aortic arch, an aortic arch graft, and an occluder system for isolating an aneurysm while occluding one or more corresponding arteries, and with bypass of those arteries being performed using one or more selected bypass grafts. The graft may be branched or branchless. The graft delivery system has a flexible sheath that is manipulated manually with the aid of a guidance system. A hoist delivery system may also be provided. The occluder system may comprise independent occluders with one or more anchor members adjacent to one end. Alternatively, the occluders can be provided as part of the aortic arch graft, either as a built-in singular self-deploying occluder or as built-in multiple occluders. A kit is also provided containing a graft, stents, occluders, and optional delivery system.
