    摘要： A surgical device is disclosed that comprises a sleeve member, a shaft member and a pair of electrodes. The shaft member extends distally of the sleeve member and has a pair of electrode channels that open at the distal end of the shaft member, wherein the electrode channels are positioned adjacent to one another. The pair of electrodes are configured to deliver energy, and one of the pair of electrodes are configured to be disposed in each electrode channel such that distal ends of each of the electrodes are arranged to protrude from the distal end of the shaft member. An irrigation annulus is formed about the electrodes. The shaft member further includes at least one lumen opening at the distal end of the shaft member.

    摘要： A method and an apparatus according to an embodiment includes a distal end portion of an optical fiber disposed inside a lumen defined along a curved path within a capillary. The distal end surface of the optical fiber can be substantially flush with a portion of an outside surface of the capillary that defines a transmissive portion. The distal end portion of the optical fiber and the curved path can be collectively configured to direct laser energy through the transmissive portion in a lateral or side-fired direction that is offset from a longitudinal axis or centerline of the capillary. In some embodiments, more than one optical fiber can be disposed along the curved path. In other embodiments, more than one curved path can be defined within the capillary such that a distal end portion of an optical fiber can be disposed along each of the curved paths.

    摘要： A medical device for fragmenting objects and aspirating remaining debris enables a physician or other medical personnel quickly and easily remove objects, such as kidney stones, from a patient. The medical device can include a dual-lumen elongated member and a handle coupled to the elongated member. A first one of the lumens provides a suction passageway, and a second one of the lumens receives a laser fiber for delivering laser energy to an object, such as a kidney stone, within the patient. The handle can include a positioning mechanism to enable the physician by manual manipulation to move and hold in place the laser fiber longitudinally within the second lumen.
