Claim 0:
1. A method for thermal coagulation necrosis of cells, the method comprising:
providing a probe having a proximal end, an opposite distal end, a proximal first conductor, a distal second conductor, a proximal first insulator, and a distal second insulator,
the proximal first insulator extending from the proximal end to the proximal first conductor,
the distal second insulator extending from the proximal first conductor to the distal second conductor, and
the proximal first conductor forming a first lumen, and the distal second conductor forming a second lumen;
withdrawing the probe in increments through tissue via a path that traverses at least some bone tissue;
for each of the increments, at least partially concurrently delivering energy in a bipolar manner between the proximal first conductor and the distal second conductor to heat a layer of tissue surrounding the probe to a temperature sufficient for the thermal coagulation necrosis of cells thereby, the energy being supplied to the probe by an electrosurgical generator that is electrically coupled to at least one of the proximal first conductor and the distal second conductor; and
deactivating at least one of a first cooling system that extends through the probe and terminates within the first lumen and a second cooling system that extends through the probe and terminates within the second lumen when the energy is being delivered to the probe, the probe being not actively cooled by the cooling system during the withdrawal of the probe.
