1. A modular device for repairing a body lumen, comprising:
- a main tubular component comprising a trunk portion having first and second legs extending therefrom, wherein said first and second legs are in fluid communication with said trunk portion, and said second leg comprises a docking site having a tubular configuration with a uniform expanded diameter and an end portion which has a bell-bottom configuration disposed inferior to said docking site;
a first tubular component, separate from said main tubular component, and configured to connect with said first leg in said body lumen;
a second tubular component, separate from said main tubular component, and configured to overlap and sealingly engage with at least said docking site of said second leg in said body lumen; and
a plurality of discrete expandable devices attached to said main tubular component, said expandable devices being positioned at different longitudinal levels along said repair device.

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 leg 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.
