IN DEN KÖRPER EINES PATIENTEN PERKUTAN IMPLANTIERBARE ENDOPROTHESE MIT HERAUSRAGENDEN WIDERHAKEN
摘要
An endoprosthetic device for treating abdominal aortic aneurysms using suprarenal fixation. A stent ring is anchored in an area above the renal arties using self-flaring barbs that project during the nitinol expansion process. Sutures extend from the stent ring to an area below the renal arties to a bifurcated trunk portion (30) comprising a nitinol fabric on a non-kinking frame. The bifurcated trunk is sealed proximal the iliac arteries and includes iliac leg holders having self-flaring retention struts for non-traumatic holding of iliac leg prosthetics. Suprarenal fixation and collapsible cells (400,500) having retention projections and barbs that only flare during the nitinol expansion process assist in lowering the devices profile and sheathability for percutaneous delivery and may provide for recapturing the anchored device.
