Abstract
Abstract An intraluminal grafting system (11) includes a hollow graft (12) which has a proximal staple (16) and a distal staple (17). The system (11) includes a capsule (18) for transporting the graft (12) through the lumen and for positioning the graft (12) upstream in a lumen which may be a blood vessel or artery. A tube (26) is connected to the capsule (18) and extends to exterior the vessel for manipulation by the user. A catheter (27) is positioned within the tube (26) to extend from the cavity and through the graft (12) to exterior the body. The catheter (27) has an inflatable membrane (3)which is in communication via a channel with inflation and deflation means (38). With the inflatable membrane (30) deflated, the capsule (18) is positioned in the lumen and manipulated to desired location. The force exerted by the inflatable membrane (30) and the structure of the staples urges the staples in the vessel, retaining the graft in position.
