Abstract
A system for repairing body lumens including a modular graft and a method for deploying the graft within the body lumen. The modular graft includes a first component having first and second legs portions which mate with second and third graft components, respectively. The second leg portion has a bell bottom shape. The modular graft further includes expandable members which aid in implanting the modular graft as well as facilitates the mating of its components. In order to repair the body lumen, the first component is placed at the repair site and thereafter the first and second legs are advanced to the repair site and attached to the first component. A further aspect of the invention is a fixation device which is adapted to perform an attachment function. The graft and the fixation device are configured to be axially separated from one another so as to allow the graft to attach to the vascular wall proximal of the graft.
