1. A method of treating spinal tissue of a patient'"'"'s body using a system comprising an energy source and first and second internally-cooled probe assemblies, wherein each of the probe assemblies comprises an electrically conductive energy delivery device electrically coupled to the energy source, the method comprising:

  • inserting the energy delivery devices of the first and second internally-cooled probe assemblies into spaced-apart treatment sites for the spinal tissue;

    delivering energy from the energy source to the spinal tissue through the energy delivery devices in a bipolar mode that concentrates delivered energy between the energy delivery devices to create a lesion within the spinal tissue;

    delivering a cooling fluid to the energy delivery devices; and

    controlling the delivery of energy and the delivery of the cooling fluid to the energy delivery devices at least in part based on a distance between the energy delivery devices such that the lesion extends between the energy delivery devices.
