Abstract
A controller for a cooled radiofrequency ablation system is configured to sequentially activate a plurality of pump assemblies with a pump activation time delay between the activation of each of the plurality of pump assemblies, measure a temperature drop delay time for each of a plurality of cooled radiofrequency ablation probes, map each respective pump assembly of the plurality of pump assemblies to a corresponding cooled radiofrequency ablation probe of the plurality of cooled radiofrequency ablation probes based on the temperature drop delay time and an activation time of each of the plurality of pump assemblies, and confirm the mapping of each respective pump assembly to the corresponding cooled radiofrequency ablation probe by comparing, for each of the plurality of cooled radiofrequency probes, the measured temperature drop delay time to an expected temperature drop delay time.
