Abstract
In some examples, a catheter includes an elongated member including at least one balloon connected to the elongated member, the at least one balloon being configured to inflate to an expanded state. In the expanded state, the at least one balloon forms at least a portion of a cavity with a wall of a vessel of the patient. The catheter including at least one electrode carried by the elongated member and having at least one surface exposed to the cavity formed by the at least one balloon. The electrode is configured to connect to an energy source that is configured to deliver, via the electrode, an electrical signal to a fluid contained in the cavity and in contact with the electrode to cause the fluid to undergo cavitation to generate a pressure pulse wave within the fluid.
