1. A method for removal of tissue from a prostate gland, comprising:
inserting a distal region of an endoscope into said prostate gland, 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 prostate gland, 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 prostate gland 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 prostate gland; delivering fluid into the prostate gland through the valve and the second channel to distend the prostate gland; energizing an electric motor to drive the cutter to cut tissue within the prostate gland; and aspirating cut tissue and fluid from the prostate gland and the endoscope through the cutter. |
