Multi-electrode ablation systems, methods, and controllers are described. In one example, a method of beginning an ablation procedure using a multi-electrode ablation system is described. The method includes selectively coupling the output of a power supply to a first electrode of a plurality of electrodes to increase a temperature at the first electrode to a first temperature set-point and limit a rate of increase of the temperature at the first electrode to a predetermined first rate.

Ablation system, methods, and controllers

Multi-electrode ablation systems, methods, and controllers are described. In one example, a multi-electrode ablation system 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.
