Abstract
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.
