Abstract
In some examples, a medical device includes a flexible elongate member configured for navigation through vasculature of a patient to a target treatment site. A distal portion of the elongate member including a first balloon portion that is inflatable to an expanded state, a second balloon portion that is inflatable to an expanded state, and a cavitation generator. When the balloon portions are in their expanded states within the vasculature, a cavity is defined between the elongate member and the target treatment site and exterior to the first and second balloon portions. The cavitation generator is configured to deliver energy to a fluid within the cavity to cause the fluid to undergo cavitation to generate a pressure pulse wave within the fluid.
