Abstract
Described herein are systems and methods for implementing a power source for a shock wave catheter system, the power source including two separate voltage sources: a bubble generation voltage source and an arc generation voltage source. In one or more examples, the power source can be configured such that the bubble generation voltage source provides a lower voltage to a pair of electrodes of the shock wave catheter system. The lower voltage can be configured to induce electrolysis of a fluid that surrounds the pair of electrodes of the shock wave catheter system for generating and growing a bubble. Once a bubble has formed, the arc generation voltage source can then be engaged to provide a high-voltage electrical pulse to the electrodes of the shock wave catheter system, thereby generating an arc (i.e., spark) across the electrodes.
