Abstract
A catheter system for imparting pressure to induce fractures in a vascular lesion within or adjacent a vessel wall, includes a catheter and a superheating system. The catheter can advance to the vascular lesion. The catheter includes an elongate shaft and a balloon coupled to the elongate shaft. The balloon includes a balloon wall. The balloon moves between a collapsed configuration and a first expanded configuration suitable for anchoring the catheter in position relative to a treatment site. The superheating system can heat a balloon fluid within the balloon rapidly enough to achieve spontaneous vaporization of the balloon fluid and to generate inertial bubbles and acoustic pressure waves. The superheating system can include a first light guide extending along the elongate shaft. The first light guide is in optical communication with a light source at a proximal portion of the first light guide.
