1. 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 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;

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