15. The multi-balloon catheter of claim 12, wherein the second moveable member is associated with the first moveable member by a connection means which connects the first and second moveable members to each other.

16. The multi-balloon catheter of claim 12, including at least one radiopaque marker secured to the shaft proximate the first balloon and at least one radiopaque marker secured to the first moveable member proximate the second inflatable balloon.

17. The multi-balloon catheter of claim 12, including an elongate guide member disposed in one of the internal passages of the shaft.

18. The multi-balloon catheter of claim 12, including a third inflatable balloon disposed on the shaft between the first inflatable balloon and the first end of the shaft.

19. An apparatus for repairing a body passageway, comprising:
