Claim 15:
16. A catheter system to induce fractures upon a vascular lesion, comprising:
a catheter configured to advance to a vascular lesion location within a blood vessel, the catheter comprising:
an elongate shaft wherein the elongate shaft defines at least a first orifice and a second orifice for fluid flow, wherein the elongate shaft further defines a propulsion fluid lumen; and
an expandable balloon coupled to the elongate shaft and surrounding the first orifice and the second orifice; and

a propulsion system comprising an external fluid flow source in fluid communication with a proximal end of the propulsion fluid lumen and an actuation valve at a distal end of the propulsion fluid lumen, wherein the propulsion system is configured to propel a pulsed jet of fluid propelled from the first orifice and from the second orifice toward a balloon wall.
