Claim Text:
1. A system comprising: 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 first and second electrodes within the balloon arranged to receive there-across a high electrical voltage pulse at an initial low current, the high electrical voltage pulse causing an electrical arc to form within the balloon, the electrical arc creating a gas bubble within the liquid, a high current to flow through the first and second electrodes, and a mechanical shock wave within the balloon; and a power source that provides the first and second electrodes with the high electrical voltage pulse at the initial low current, said power source including a sensor for monitoring a parameter that varies during each voltage pulse and wherein the high electrical voltage pulse is terminated when the monitored parameter reaches a predetermined value.
