Abstract
An ablation system observes and monitors ablation parameters, including temperature, impedance, and/or the system's own closed-loop response to these ablation parameters. The system comprises a catheter with electrodes and a detection circuitry configured to detect an ablation parameter for each electrode, a controller coupled to the catheter, the controller having a processing unit and a memory storing instructions that, when executed by the processing unit, cause the processing unit to: receive a detected ablation parameter for each electrode from the detection circuitry, determine when a detected ablation parameter violates a defined ablation parameter for each electrode, control a power supplied to each violating electrode to have a reduced power, detect a rate of power reduction for each violating electrode, and stop the power supplied to each violating electrode when a respective detected rate of power reduction exceeds a threshold rate of power reduction.
