1. A method for treating impingement of a nerve of a spinal canal caused by spinal stenosis within a human body, said spinal canal including a vertebral foramen the method comprising:
providing a catheter having an expandable member located within the catheter;
providing a cannula having a blunt end with at least one stylet having a blunt end located internally of said cannula;
introducing the catheter into the general proximity of the impinged nerve of the spinal canal;
introducing the stylet into the general proximity of the impinged nerve of the spinal canal;
advancing the expandable member from the catheter into the spinal canal in a posterior to anterior position;
expanding the expandable member;
alleviating the pressure of the nerve impingement of the spinal canal with the expanded expandable member; and
removing the catheter and the cannula and stylet from the human body.
