Abstract:
1. A method for removal of tissue from a uterus, comprising: inserting a distal region of an endoscope into said uterus, the endoscope including a valve and an elongated member defining discrete first and second channels extending from a proximal region of the elongated member to the distal region, the second channel having a proximal end in communication with the valve such that fluid from the valve is able to flow into and through the second channel to the uterus, and the first channel having a light guide permanently affixed therein and being sealed from the second channel to prevent fluid from the valve from entering the uterus through the first channel; followed by: inserting a motor driven cutter into the second channel such that a distal cutting region of the cutter extends distally beyond the endoscope in the uterus; delivering fluid into the uterus through the valve and the second channel to distend the uterus; energizing an electric motor to drive the cutter to cut tissue within the uterus; and aspirating cut tissue and fluid from the uterus and the endoscope through the cutter.
