1. A method for generating a shock wave in a shock wave catheter system, the method comprising:
applying a first voltage, using a first voltage source, to one or more electrodes of the shock wave catheter system to prime an aqueous environment or generate one or more bubbles in a fluid surrounding the one or more electrodes; and
applying a second voltage, using a second voltage source, to the one or more electrodes to generate an electrical arc at the one or more electrodes,
wherein the first voltage source and the second voltage source are independently controllable; and
applying a third voltage to the one or more electrodes of the shock wave catheter system to cause metal to be deposited on the one or more electrodes, wherein the applied third voltage is less than the applied first voltage.
