1. A balloon catheter for delivering shockwaves to a calcified lesion comprising:

  • an elongated carrier;

    a flexible balloon mounted on the elongate carrier, said balloon being fillable with a conductive fluid;

    a pair of electrodes on the elongated carrier within the balloon; and

    a power source coupled to the electrodes for supplying a voltage to the electrodes to generate an arc in the fluid within the balloon and causing current to flow between the electrodes;

    wherein the power source includes a current sensor for detecting the current flow between the electrodes, and wherein when the current reaches a predetermined value, the sensor generates a signal that causes the power source to terminate the voltage supply to the electrodes.
