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 further characterized by curved segments between the bends which a create an anchor having a reverse barrel shape.
