Patent number: 11419679Abstract: 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.Type: GrantFiled: March 28, 2019Date of Patent: August 23, 2022Assignee: Lumenis Ltd.Inventors: Arkady Khachaturov, Tal Waisman, Eyal Benisty, Mikhael Feldchtein

Patent number: 10799291Abstract: 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.Type: GrantFiled: November 1, 2018Date of Patent: October 13, 2020Assignee: LUMENIS LTD.Inventors: Tal Waisman, Arkady Khachaturov, Assaf Preiss

Patent number: 10687893Abstract: A method for cosmetically treating skin tissue is disclosed in which a combination of laser energy and RF energy is applied to the skin tissue. In the method, a microchannel is first formed in the skin tissue having a length, a depth and a width by ablating the skin tissue. After that, RF electrodes are placed on the skin tissue on either side of the width dimension of the microchannel, followed by activation of RF energy to drive RF energy below the depth of the microchannel formed, and this the RF energy is driven deeper into the skin tissue than would have occurred in the absence of the microchannel.Type: GrantFiled: October 20, 2017Date of Patent: June 23, 2020Assignee: LUMENIS LTD.Inventors: Vladimir Lemberg, Vitali Epshtein, Yoni Iger, John Lee Pannell
