Classification: CPC A | IPC A

Claim 0:
1. A medical device, comprising:
an elongated body having a central longitudinal axis;
a distal elongated body portion extending from the elongated body and distal to the elongated body along the central longitudinal axis;
a balloon positioned along the distal elongated body portion, the balloon having an interior balloon surface and an exterior balloon surface and configured to receive a fluid to inflate the balloon such that the exterior balloon surface contacts a calcified lesion within a vasculature of a patient;
a pressure wave emitter positioned along the central longitudinal axis of the elongated body within the balloon, the pressure wave emitter configured to propagate at least one pressure wave through the fluid to fragment the calcified lesion;
wherein the pressure wave emitter comprises an optical fiber configured to transmit laser energy into the balloon, and
wherein the laser energy is configured to create a cavitation bubble in the fluid upon contact with the fluid to generate the at least one pressure wave, and
a fiber positioner at least partially surrounding each of the distal elongated body portion and the optical fiber, the fiber positioner comprising a distal face and a proximal face opposite the distal face,
wherein the proximal face of the fiber positioner and the distal face of the fiber positioner are longitudinally located within the balloon;
a shroud configured to prevent contact between the optical fiber and the balloon,
wherein the shroud comprises:
a tine including a curved end configured to provide a smooth point of contact with the balloon; and
a skirt including a flexible material extending from the tine.
