  • Patent number: 9757199
    Abstract: A surgical laser system includes a first laser source, a second laser source, a beam combiner and a laser probe. The first laser source is configured to output a first laser pulse train comprising first laser pulses. The second laser source is configured to output a second laser pulse train comprising second laser pulses. The beam combiner is configured to combine the first and second laser pulse trains and output a combined laser pulse train comprising the first and second laser pulses. The laser probe is optically coupled to an output of the beam combiner and is configured to discharge the combined laser pulse train.

  • Patent number: 9277853
    Abstract: An endoscope for an optical fiber provides for inflow and outflow of irrigant. A telescope is included having a field of view directed into a working region. The endoscope defines a “hooded region” with an extended, blunt tip. The optical fiber fits within the endoscope has a side or end firing tip with an emission surface. A guide element is adapted to movably support the optical fiber in a position spaced away from the working region, and limit lateral movement of the tip without preventing longitudinal and rotational movement. An irrigant flow arrangement operates to direct inflowing irrigant over the emission surface of the tip. The fiber is assembled with a fiber coupler, a handle, a fiber port cap, and a travel limiter fixed to the fiber at a predetermined distance from the tip. The travel limiter cooperates with the endoscope and the fiber port cap to limit longitudinal and rotational movement of the fiber.

  • Publication number: 20150272676
    Abstract: An optical device including an optical fiber having a longitudinal axis and an optical fiber core with a distal end having a distal terminating end configured to discharge a first laser energy in a first direction and a second laser energy in a second direction. The optical device also includes a fiber cap having an interior cavity and an opening to the interior cavity, where the distal end of the optical fiber core is received within the interior cavity through the opening. A cladding is included on the distal end of the optical fiber core between the optical fiber core and the fiber cap.

  • Publication number: 20140188096
    Abstract: A surgical laser tool comprises an output member that includes an output laser fiber, a probe tip, and electrical contacts. The probe tip is attached to a distal end of the output laser fiber. Electromagnetic energy transmitted through the output laser fiber is discharged through the probe tip. The electrical contacts are supported at a proximal end of the output member.
