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.

Claim (Index 1):
A medical laser system for treating a target tissue portion with a laser beam, said target tissue portion being mobile and immersed in a liquid medium formed primarily of water within a body lumen, said system comprising:\n a laser device for generating an output laser beam; an optical fiber for guiding the laser beam to the tissue portion, said fiber having a delivery end positioned close to but spaced from the target tissue portion to be treated; and a controller for controlling the laser device and functioning to sequentially generate at least one series of first and second laser pulses, the first laser pulse and the second laser pulse being substantially along the same longitudinal axis, and wherein the first laser pulse has an energy sufficient to form a vapor bubble in the liquid medium at the delivery end of the fiber and wherein the second laser pulse is generated a predetermined time after the first laser pulse, said predetermined time being selected to allow the vapor bubble created by the first laser 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 portion, wherein the controller controls the initiation of said second laser pulse such that it is delivered to the tissue through the vapor bubble after the vapor bubble has reached its maximum extent and has begun to collapse whereby the collapsing bubble causes the tissue portion to remain substantially stationary when the second laser pulse is delivered, thus reducing retropulsion of the tissue portion.
