Patent ID: 7025779

Claim:
A method of inhibiting diametric expansion of an aneurysm having a lumen wall, the aneurysm having an aneurysm neck region at one end having a width and a shoulder region adjacent the neck region having a diverging width greater than the width of the aneurysm neck region, the method comprising deploying an endograft in the aneurysm, the endograft having an endograft neck with a diameter approximately equal to the width of the aneurysm neck region and a shoulder portion having a device diameter profile that conforms to a lumen diameter profile of the shoulder region of the aneurysm, wherein the shoulder portion comprises part of a bulbous portion, and the endograft neck is located adjacent the bulbous portion, wherein the bulbous portion has a length characterized by a diverging and converging diameter greater than the endograft neck diameter along the bulbous portion length, the endograft having a diameter profile in said converging diameter part of said bulbous portion length that does not conform to the body lumen diameter profile, the endograft neck and the shoulder portion comprising a plurality of affixation members for affixing to the lumen wall of the aneurysm.
