Patent attributes
A catheter assembly includes a catheter comprising a flexible elongated member including a distal portion that includes a tubular body defining an inner lumen and a plurality of body apertures that extend through a sidewall of the tubular body into the inner lumen, and a plurality of primary electrodes positioned along the tubular body. The catheter assembly includes a wire defining at least one secondary electrode, the wire being configured to be slidably moved through the inner lumen of the tubular body, where the wire and the plurality of primary electrodes are configured to electrically couple to an energy source that delivers an electrical pulse to a fluid in contact with the plurality of primary electrodes and the at least one secondary electrode to cause the fluid to undergo cavitation to generate a pressure pulse wave within the fluid.
