Abstract:
1. A system, comprising: an energy delivery apparatus having a plurality of electrodes configured to deliver energy to respective treatment sites; an energy supply apparatus that powers the energy delivery apparatus; and an energy supply controller that controls the power from the energy supply apparatus to the energy delivery apparatus based on a plurality of different desired impedance values that correlate to temperatures that fall within a desired non-ablative range, wherein each of the different desired impedance values corresponds to at least one of a different spacing between adjacent electrodes of the plurality of electrodes and a different distance between adjacent treatment sites, wherein the plurality of electrodes are movable between a plurality of radial positions relative to a longitudinal axis of the energy delivery apparatus, wherein the spacing between adjacent electrodes of the plurality of electrodes and the distance between adjacent treatment sites are determined by the radial position of the plurality of electrodes.
