Claim 14:
15. A method for treating a spinal stenosis comprising:
inserting a membrane from a non-treatment spinal level at an insertion location, the membrane having a distal end that protects duramater tissue during removal of a spinal stenosis along a spinal region of a spine of a patient;
introducing a tubular body into the spinal region at a treatment level of the spine along a contralateral oblique axis extending across a midline of the spine such that the tubular body is inserted at a different location than the insertion location of the membrane, and thereby positioning a distal end of the tubular body into a spinal stenosis area;
fluoroscopically visualizing the spinal stenosis area along the contralateral oblique axis to view a tissue removal device inserted through the tubular body and the membrane in the spinal region; and
removing tissue from the spinal stenosis area as the tissue removal device is inserted along one side of the membrane.
