1. A method of withdrawing a probe through a tissue via a path that traverses at least some bone tissue, the method comprising:

  • withdrawing the probe incrementally through the path and at least partially concurrently delivering energy in a bipolar manner from an active tip of the probe to heat a layer of tissue surrounding the probe to a temperature sufficient for thermal coagulation necrosis of cells;

    measuring a temperature of the layer of tissue surrounding the probe along at least a portion of the path prior to each incremental withdrawal to determine if the temperature of the layer of tissue surrounding the probe is sufficient for the thermal coagulation necrosis of the cells, the measuring of the temperature of the layer of tissue surrounding the probe being measured by a temperature sensor, the temperature sensor being positioned on an exterior surface of the active tip of the probe;

    providing an indication to a user when the temperature of the layer of tissue surrounding the probe reaches the temperature sufficient for the thermal coagulation necrosis of the cells; and

    deactivating a cooling system that is associated with the probe 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.
