MULTI-ELECTRODE ABLATION SYSTEM WITH A CONTROLLER FOR DETERMINING A THERMAL GAIN OF EACH ELECTRODE

摘要

A multi-electrode ablation system (100) is described that includes a power supply configured to be coupled to a plurality of electrodes and a controller coupled to the power supply. The controller is configured to determine a thermal gain of each electrode of the plurality of electrodes. For each electrode of the plurality of electrodes, the controller sets a power limit based at least in part on said electrode's determined thermal gain. The power limit establishes a maximum power that may be dissipated through said electrode.
