Publication number: 20160135892Abstract: A surgical laser system includes an array of laser diodes that are configured to output laser energy, a fiber bundle, a delivery fiber, and a tubular sheath. The fiber bundle includes a plurality of optical fibers and has a proximal end that is configured to receive laser energy from the array of laser diodes. The delivery fiber includes a proximal end that is configured to receive laser energy from a distal end of the fiber bundle. The tubular sheath defines a lumen, in which at least a portion of the delivery fiber is disposed. The tubular sheath is insertable into a working channel of an endoscope or a cystoscope. A distal end of the tubular sheath is configured to deliver laser energy discharged from the delivery fiber into a body of a patient.Type: ApplicationFiled: November 13, 2015Publication date: May 19, 2016Inventors: Honggang Yu, Rongwei Jason Xuan, Jian James Zhang, David N. Horn, Xirong Yang, Thomas Hasenberg

Publication number: 20160135893Abstract: Expandable laser catheters for utilizing laser energy to remove obstructions from body passages are described. In one embodiment, the laser catheter includes a shaftway having a distal end including a flexible portion configured in a series of radial folds. Multiple optical fibers, configured to transmit laser energy, extend along the shaftway and are attached to the flexible portion. An inflatable, ring-shaped balloon is attached to the catheter within the flexible portion. In use, the catheter is inserted into a body passage such as an artery, and advanced until the distal end is adjacent to an obstruction. The balloon is inflated to expand the flexible portion and to bring the optical fibers nearer the inner wall of the body passage. Laser energy is directed by the optical fibers toward targeted regions of the obstruction, As the catheter is advanced and the process repeated, a core is formed from the obstruction and contained within the flexible portion.Type: ApplicationFiled: January 21, 2016Publication date: May 19, 2016Inventors: Thomas R. Winston, John M. Neet

Publication number: 20160135894Abstract: Medical apparatus includes an endoscope, which includes a distal end configured for insertion into a body cavity and which includes an imaging assembly, configured to capture and output an image of a region of the body cavity in proximity to the distal end. An energy source is configured to emit pulses of energy through an energy guide. A control unit is configured to process the image so as to identify a target mass in the body cavity and to verify that an aiming beam directed through the energy guide is incident on the target mass and, responsively to so verifying, to actuate the energy source to direct a pulse of the energy via the energy guide onto the target mass.Type: ApplicationFiled: January 24, 2016Publication date: May 19, 2016Inventors: Shai Finkman, Adi Navve
