摘要:
Systems and methods for treating spinal stenosis include endoscopic access devices and bone removal devices used to perform a foraminotomy or other bone removal procedures. A bone removal device includes a cannulotome with an endoscopic imaging lumen. Optionally, an endoscope retaining device can be used to facilitate advancement of the endoscope through the cannulotome.
