Abstract

The endovascular graft disclosed includes a main tubular body having a first end portion and an exterior surface. The first end portion has a flanged end disposed on exterior surface and extending radially thereabout, for engaging blood vessel walls. The graft may be made from a surgically implantible material. The graft has a second end portion of the main body that can either be a continuation of the main body or split into two tubular legs. The two tubular legs, each define a bore. The bore of the main body is in communication with the bores of the legs. A method of installing the endovascular graft includes installing the graft intraluminially to the operative site using a catheter having a balloon portion. The graft is positioned to extend through a damaged portion of a blood vessel. The balloon portion is positioned within a bore defined by the graft proximal to a first end portion, the first end portion having a flanged end. The balloon is expanded such that the flanged end expands into a blood vessel forming a raised portion on an exterior surface of the blood vessel. Finally, surgical clips are atraumatically applied to the raised portion compressing vessel tissue about the flanged end to capture the graft within the blood vessel.
