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 carry a voltage there-across including an initial high electrical voltage at an initial low current, the initial high electrical voltage causing an electrical arc to form within the balloon, the electrical arc causing a gas bubble within the liquid, a high current to flow through the first and second electrodes, a decrease in the initial high electrical voltage, and a mechanical shock wave within the balloon; and a power source that provides the first and second electrodes with a drive voltage pulse that creates the initial high electrical voltage at the initial current and that terminates the drive voltage pulse in response to the decrease in the initial high electrical voltage.
