20130250985 | LASER SYSTEM CHILLER - A laser system includes a laser element, a pump source configured to input light to the laser element, a first cooling circuit and a second cooling circuit. The first cooling circuit includes a first pump configured to drive a first flow of cooling liquid through a first fluid pathway, a first primary heat exchanger configured to cool the first flow of cooling liquid, and a laser element heat exchanger configured to remove heat from the laser element using the first flow of cooling liquid. The second cooling circuit includes a second pump configured to drive a flow of cooling liquid through a second fluid pathway, a second primary heat exchanger configured to cool the second flow of cooling liquid, and a pump source heat exchanger configured to remove heat from the pump source using the first and second flows of cooling liquid. | 09-26-2013 |
20150045779 | LASER TISSUE ABLATION SYSTEM - Embodiments of a laser ablation system include a shaft, a balloon and a laser fiber. The shaft has a proximal end and a distal end. The balloon is attached to the distal end of the shaft, a portion of which is disposed within the balloon. A light dispenser at a distal end of the laser fiber deliver laser light through the balloon. A central axis of the balloon is aligned with a longitudinal axis of the shaft. The balloon has a variable transparency such that the transmission of laser light through the balloon is non-uniform along the central axis. Accordingly, an energy of laser light transmitted from the light dispenser through the balloon to the targeted tissue varies due to the variable transparency of the balloon. | 02-12-2015 |
