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.

Claims

1. A device for repairing a body lumen, comprising:

a main tubular component, said main tubular component having a superior end, an inferior end, and a trunk portion with first and second legs extending therefrom, said second leg extends beyond said first leg and includes an end portion which has a bell-bottom configuration;

a first tubular component configured to mate with said first leg; and

a second tubular component configured to meet with said second leg.

2. The repair device of claim 1, further comprising a main expandable device configured proximate said superior end of said main tubular component.

3. The repair device of claim 1, further comprising a first docking site positioned within said first leg, said first docking site including a first minor expandable device.

4. The repair device of claim 3, further comprising a second docking site positioned within said second leg, said second docking site including a second minor expandable device.

5. The repair device of claim 4, said first leg further including a first constriction.

6. The repair device of claim 5, said second leg including a second constriction.

7. The repair device of claim 6, wherein said second constriction is positioned superior to said bell-bottom portion.

8. The repair device of claim 7, said first tubular component further including a plurality of first supplemental expandable devices, said first supplemental expandable devices being spaced along said first tubular component.

9. The repair device of claim 8, said second tubular component further including a plurality of second supplemental expandable devices, said second supplemental expandable devices being spaced along said second tubular component.

10. The repair device of claim 9, wherein said first constriction is received between adjacent first supplemental expandable devices.

11. The repair device of claim 9, wherein said second constriction is received between adjacent second supplemental expandable devices.

12. The repair device of claim 6, further comprising a radiopaque marker positioned at said second constriction.
