Claim 27:
28. A method for treating a spinal stenosis comprising:
introducing a tubular body into the spinal region along a contralateral oblique axis of a patient to access a spinal stenosis area, the contralateral oblique axis being in a range of 35 to 45 degrees offset from a midline of the spine of the patient such that a distal end of the tubular body is inserted across the midline and into a spinal stenosis while avoiding contact with nerves of the spinal canal;
fluoroscopically visualizing the spinal stenosis area and a tissue removal device inserted through the tubular body and into the spinal stenosis along the contralateral oblique axis; and
removing tissue from the spinal stenosis as the tissue removal device is inserted sequentially and in multiple planes into the spinal stenosis.
