Claim Text:
1. A valvuloplasty system comprising: an elongate tube; a first balloon chamber configured to be placed adjacent to a valve; a second balloon chamber configured to be placed adjacent to the valve at a location spaced from the first balloon chamber, wherein the first and second balloon chambers are located at the distal end of the elongate tube; a first shock wave generator located within the first balloon chamber, wherein the first shock wave generator is mounted on a first elongate element that is slidably received within the elongate tube; a second shock wave generator located within the second balloon chamber, wherein the second shock wave generator is mounted on a second elongate element that is slidably received within the elongate tube; wherein the first and second balloon chambers are each inflatable with a liquid and the first and second shock wave generators are each configured to produce a shock wave within the first and second balloon chambers to propagate through the liquid for impinging upon the valve, and wherein the first and second shock wave generators are each configured to be axially and/or longitudinally movable within the first and second balloon chambers to vary the shock wave impingement upon the valve.
