The present invention provides methods for treating conditions such as abdominal aortic aneurysms and the like which involve the direct placement of a bifurcated graft in the afflicted area. The surgical procedures can be performed proximally, from above the junction of the abdominal aorta and the renal arteries, or distally through the iliac arteries. The present invention relates also to a bifurcated mandril for delivery of a bifurcated graft to patients and to a balloon expandable universal access sheath which ccan be used in surgical procedures. Finally, the present invention relates to a self-expanding stent which may be used to anchor a graft such as an abdominal aortic graft, in place. The stent may also be used following procedures such as, for example, balloon angioplasty. |
