<p>An attachment assembly, and repair graft are disclosed for securing a graft (3) to repair a vessel (1) having an aneurysm therein. The attachment assembly comprises an attachment cuff (12) such that the graft is not dimensionally dependent upon the size of the vessel. A visualization apparatus (6) is also disclosed for real time direct viewing of an interior of a vessel. A penetration apparatus (7) 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 (900) is also disclosed that comprises a sealing assembly (930) for preventing the loss of blood from the vessel during the insertion, and subsequent removal of surgical components during the surgical procedure.</p> |
