An endoluminal device for affixation to a wall of a body lumen having a neck region defined by a relatively narrow width and a shoulder region that diverges from the neck region to a relatively wider width. The device comprises a shoulder portion, which may be part of a bulbous portion, having a diameter profile that conforms to the shoulder region, and, in some embodiments, a plurality of affixation members in an area of the device that typically extends from a distal end of the device through the shoulder portion. In one embodiment, the device comprises an endograft for repair of an aneurysm, such as an abdominal aortic aneurysm (AAA). Methods of using the endograft to inhibit continued diametric expansion of the aneurysm and to inhibit endoleak formation and migration of the endograft are also described.
An endoluminal device for affixation to a wall of a body lumen, the body lumen having a neck region defined by a relatively narrow width and a shoulder region that diverges from the neck region to a relatively wider width, the device comprising a shoulder portion having a device diameter profile that conforms to a lumen diameter profile of the shoulder region for deployment in the shoulder region.
An endoluminal device adapted to repair an abdominal aortic aneurysm (AAA) for affixation to a wall of a body lumen, the body lumen having a renal neck region, defined by a relatively narrow width, and a renal shoulder region that diverges from the renal neck region at a distal end of the aneurysm and an iliac neck region, defined by a relatively narrow width, and an iliac shoulder region that diverges from the iliac neck region at a proximal end of the aneurysm, the device comprising a distal shoulder portion having a diameter profile that conforms to the renal shoulder region for deployment in the renal shoulder region;
The device of claim 29 wherein the distal shoulder portion is part of a distal bulbous portion and each of the one or more proximal shoulder portions are part of a corresponding proximal bulbous portion.
An endograft for repair of an abdominal aortic aneurysm (AAA) having a lumen wall, the endograft comprising a stent at least partially lined or covered by a graft material and having a distal end comprising a distal neck having a first diameter and a first bulbous portion located proximally of the distal neck and having a proximally diverging then converging diameter greater than the first diameter, at least the distal neck and part of the first bulbous portion comprising a plurality of affixation members that project radially outward from the device for affixation to the lumen wall of the AAA.
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, the endograft neck and the shoulder portion comprising a plurality of affixation members for affixing to the lumen wall of the aneurysm.
A method of inhibiting endoleak formation and migration of an endograft deployed in a lumen having a lumen wall, a lumen neck region having a lumen neck width, and a lumen shoulder region adjacent the lumen neck region having a diverging width greater than the lumen neck region width, the method comprising:
A method of repairing a body lumen having a lumen wall, a lumen neck region having a lumen neck width, and a lumen shoulder region proximal the lumen neck region having a diverging width greater than the lumen neck region width, the method comprising the steps of:
A method of repairing an abdominal aortic aneurysm (AAA) in a body lumen having a lumen wall, the body lumen having, at a distal end of the AAA, a renal neck region, defined by a relatively narrow width, and a renal shoulder region that diverges from the renal neck region;
