Abstract: A method of optimizing the irradiation of a target with laser radiation includes selecting and mounting on a laser radiation delivery device either a waveguide or optical fiber type to be used; also, selecting at least the following parameters: selecting the total energy of the at least one train of pulses to be delivered to the target, and selecting the distance from the distal delivery end to the target; then, initiating irradiation of the target for the at least one train of pulses by generating a first laser pulse with sufficient energy (Ei) to form a vapor bubble in a liquid medium; allowing the vapor bubble formed to expand an amount sufficient to displace a substantial portion of the liquid medium from the space between the distal delivery end and the target; and, thereafter, after the selected time delay (Td) sufficient for the formed vapor bubble to reach its optimum extent, generating a second laser pulse (Ep), the second laser pulse being delivered to the target through the formed vapor bubble.

Abstract: Apparatus for the treatment of a target tissue with a laser beam in which the target tissue is immersed in a liquid medium within a body lumen. The laser device is configured to provide one or more laser pulses which are configured by a controller to have an energy sufficient to form one or more vapor bubbles in the liquid medium at the distal delivery end of the fiber. The one or more pulses are configured by the controller to: first, cause a vapor bubble to be formed distally of the distal end portion of the endoscope and around the distal delivery end of the optical fiber; second, cause a second bubble to be formed distally of the first bubble; and, third, inflate the second bubble as the first bubble has begun to collapse to expand an amount sufficient to displace a substantial portion of the liquid medium from the space between the distal delivery end of the fiber and the target tissue.

Abstract: A method of treating a mobile target tissue with a laser beam includes: providing a laser device for generating a laser beam and providing an optical fiber having a delivery end for guiding the laser beam to the target tissue; a controller causes the laser device to generate one or more laser pulses substantially along the same longitudinal axis. The controller causes the laser device to provide one or more laser pulses. The one or more pulses are selected to allow a vapor bubble formed by the one or more pulse to expand an amount sufficient to displace a substantial portion of the liquid medium from the space between the delivery end of the fiber and the target tissue. The one or more pulses are delivered to the target tissue through the vapor bubble after the vapor bubble has reached its maximum extent and has begun to collapse to reduce retropulsion of the mobile target tissue.
