Abstract
Innovative fasteners are disclosed for use in repairing a vessel having an aneurysm. The fasteners comprise either coiled spring or ring type fasteners. An attachment assembly and repair graft are also disclosed for use in the repair of the vessel. An attachment assembly comprises an attachment cuff such that the graft is not dimensionally dependent upon the size of the vessel. A visualization apparatus is also disclosed for real time direct viewing of an interior of a vessel. A penetration apparatus is disclosed for use in forming treatment specific holes in a potentially calcified vessel wall which facilitates thereafter the securing of the graft and attachment assembly to the vessel wall. An introducer sheath device is also disclosed that comprises a sealing assembly for preventing the loss of blood during the insertion and subsequent removal of surgical components during the surgical procedure.
