Abstract
A method in which a probe is advanced between a neural tissue structure and a non-neural tissue structure such as the intervertebral foramen. The probe includes electrodes on opposite surfaces. Threshold currents required to stimulate action potentials for each electrode are determined. A ratio of the threshold currents are calculated. Tissue is removed from the non-neural tissue structure when the ratio is greater than a predetermined threshold.
