Electrosurgical device and methods

An ablation system for delivering energy to nervous tissue near a tumor located at least partially within a vertebral body, the ablation system comprising:

• a generator configured to supply power to the ablation system;
• a bipolar probe configured to deliver the energy to the nervous tissue near the tumor, the bipolar probe having an active tip including at least two electrodes, the at least two electrodes including at least a tubular outer electrode defining a first lumen having a longitudinal axis and a 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;
• and
• a coolant supply configured to cool the outer electrode and the inner electrode by flowing a coolant within the second lumen of the inner electrode when the energy is being delivered to the nervous tissue to limit charring of tissue surrounding the surface of the at least two electrodes.
