Abstract:
1. A method for modifying a tissue, said method comprising: providing a shaft, a lumen and a distal end, the lumen extending to a nozzle positioned near the distal end of the shaft, the nozzle comprising a restriction sized smaller than the lumen, wherein an optical fiber extends along the shaft to a light emitting end located within the lumen near the distal end of the shaft and the restriction; generating a pressurized stream of a light transmissive liquid medium with the restriction sized smaller than the lumen; coupling a source of coherent light into the stream of the light transmissive medium with the optical fiber, wherein the light emitting end of the optical fiber and the restriction are arranged near the distal end with the light emitting end spaced from the restriction to focus coherent light into the restriction and the fluid stream emanating from the restriction and wherein said coherent light is transmitted through said stream by total internal reflection; and directing the stream from the restriction to the tissue.
