Abstract
In a multi-electrode ablation system, method, and controller, the controller is configured to measure a first current through a common return path when a first voltage is applied by a power supply to a first electrode of a plurality of electrodes, measure a second current through the common return path when a second voltage is applied by the power supply to a second electrode of the plurality of electrodes, measure a third current through the common return path when a third voltage is applied by the power supply concurrently to the first electrode and the second electrode, and determine a common path impedance based at least in part on the first voltage and the first current, the second voltage and the second current, and the third voltage and the third current.
