ABSTRACT:
A graft assembly for securely position a graft at a predetermined location across an abdominal aortic aneurysm. The assembly includes a resilient self expanding anchor that is secured to the distal end of a mesh graft. The anchor is formed from a single wire having a series of zigzag bends, such that when the ends of the wire are attached a tubular anchor is produced. The anchor is further characterized by curved segments between the bends which a create an anchor having a reverse barrel shape.
