PROBLEM TO BE SOLVED: To provide a reinforced balloon catheter.SOLUTION: One embodiment of the present invention discloses a balloon catheter employing a reinforced, co-axial, duel lumen design that is operable to use with large gauge guidewires. In certain embodiments, at least one of the lumens is formed of a multilayer, tubular element in which one of the layers functions, in part, to provide radial reinforcement to the tubular element. In another embodiment of the present invention, a distal portion of an outer lumen is locked or fixed to a portion of an inner lumen. A proximal portion of a balloon is attached to the distal portion of the outer lumen, and a distal portion of the balloon is attached to a distal portion of the inner lumen.SELECTED DRAWING: Figure 1 |
