Abstract
A system for breaking obstructions in body lumens includes a catheter including an elongated carrier, a balloon about the carrier in sealed relation thereto, the balloon being arranged to receive a fluid therein that inflates the balloon, and an arc generator including at least one electrode within the balloon that forms a mechanical shock wave within the balloon. The system further includes a power source that provides electrical energy to the arc generator.

21. A catheter comprising:
-
An elongated carrier; A balloon about the carrier in sealed relation thereto, the balloon being arranged to receive a fluid therein that inflates the balloon and having an inner surface; and a shock wave generator asymmetrically located within the balloon with respect to the inner surface of the balloon that forms a mechanical shock wave within the balloon. - View Dependent Claims (22, 23, 24)

25. An angioplasty catheter comprising:
-
an elongated carrier, the carrier defining a guide wire sheath having a guide wire lumen; a balloon about the carrier in sealed relation thereto, the balloon having an outer wall, being arranged to receive a fluid therein that inflates the balloon, and having a symmetrical configuration with a center line, the guide wire sheath being centered along the center line of the balloon; and an arc generator within the balloon between the guide wire sheath and the balloon outer wall that forms a mechanical shock wave within the balloon, - View Dependent Claims (26, 27)
