Abstract
A process for cleaning and/or shaping passages, comprising providing an optical fiber having a diameter sufficiently small to be introduced into the passage and having a free end provided with a radiation focussing element; introducing the free end of the fiber into the passage so that the focal point defined by the radiation focussing element is located adjacent the region to be cleaned or shaped; providing a liquid in the passage at the location of the focal point of the radiation focussing element; and supplying pulses of laser radiation to the fiber so that the radiation exits the fiber via the free end to provoke a cavitation of vapor at the interior of the irrigating liquid.

A process for cleaning and/or shaping a passage, comprising:
- providing an optical fiber having a diameter sufficiently small to be introduced into the passage and having a free end provided with a radiation focussing element;
- introducing the free end of the fiber into the passage so that the focal point defined by the radiation focussing element is located adjacent the region to be cleaned or shaped;
- providing a liquid in the passage at the location of the focal point of the radiation focussing element;
- and supplying pulses of laser radiation to the fiber so that the radiation exits the fiber via the free end to transform a portion of the liquid into vapor and provoke a cavitation of the vapor at the interior of the liquid.
