Claim:
1. A method of treating pain generated by nervous tissue at an interface between bone of a vertebral body and a tumor located at least partially within the vertebral body, the method comprising: delivering energy to the nervous tissue using a single bipolar probe having an active tip comprising at least two electrodes, the at least two electrodes including at least a generally tubular outer electrode defining a first lumen having a longitudinal axis, and a generally tubular inner electrode defining a second lumen having a longitudinal axis extending coaxially with the longitudinal axis of the first lumen along at least a portion of the outer electrode, the energy being sufficient to limit generation of pain signals by the nervous tissue; and cooling the outer electrode and the inner electrode by flowing a coolant within the second lumen of the inner electrode as the energy is being delivered to the nervous tissue to limit charring of the tissue at the surface of the at least two electrodes.
