Leicht entfernbarer und in den Körper wieder einsetzbarer Stent

摘要

In accordance with the present invention there is provided a pre-cursor stent for positioning within the infrarenal neck, between an abdominal aortic aneurysm and the renal arteries of a patient to assist in repairing the abdominal aortic aneurysm. The stent is designed to be coupled to a graft for directing blood flow through the aneurysm. The stent is made from a substantially cylindrical self-expanding member having a proximal end, a distal end, a longitudinal axis extending therebetween and an interior. The precursor stent further includes at least two spaced apart longitudinal legs having distal and proximal ends, the proximal ends of the legs attached to the distal end of the member, the legs extending distally from the member, each the leg including a flange adjacent its distal end. Also in accordance with the present invention is an aortic graft, having the above mentioned precursor stent attached thereto when fully deployed. Further in accordance with the present invention is a delivery apparatus for the above described precursor stent.
