The device of the present invention guides the insertion of a medical device into the spinal epidural space of a vertebral column. Preferably, the device will be dimensioned to guide insertion of a medical device through a tubular retractor. Further preferably, the device may be used by surgeons to dissect the dura mater away from the lamina. Still further preferably, the device would protect the spinal cord from injury during insertion of a spinal cord stimulator by guiding the spinal cord stimulator through the epidural space at an angle substantially parallel to the spinal cord.
