System and method to map active RF channels to respective pump heads for cooled radiofrequency ablation

A method of mapping a plurality of cooled radiofrequency probes to respective pump assemblies for cooled radiofrequency ablation, the method comprising:

• sequentially activating each pump assembly of a plurality of pump assemblies;
• mapping each cooled radiofrequency probe of the a plurality of cooled radiofrequency probes to a respective pump assembly connected thereto by measuring a temperature drop delay time for each cooled radio frequency probe, wherein the temperature drop delay time is the amount of time for cooling fluid to reach a tip of the cooled radiofrequency ablation probe and initiate a temperature decrease at the tip of the cooled radiofrequency ablation probe after activation of a first pump assembly of the plurality of pump assemblies;
• and
• confirming the mapping of each cooled radiofrequency probe to the respective pump assembly by comparing the measured temperature drop delay time to an expected temperature drop delay time for each cooled radiofrequency probe, wherein expected temperature drop delay time is calculated from a recorded activation time of each cooled radiofrequency probe.

A non-transitory computer readable medium having instructions stored thereon that, when executed by a processor, cause a device to:

• sequentially activate each pump assembly of a plurality of pump assemblies;
• map each cooled radiofrequency probe of the a plurality of cooled radiofrequency probes to a respective pump assembly connected thereto by measuring a temperature drop delay time for each cooled radio frequency probe, wherein the temperature drop delay time is the amount of time for cooling fluid to reach a tip of the cooled radiofrequency ablation probe and initiate a temperature decrease at the tip of the cooled radiofrequency ablation probe after activation of a first pump assembly of the plurality of pump assemblies;
• and
• confirm the mapping of each cooled radiofrequency probe to the respective pump assembly by comparing the measured temperature drop delay time to an expected temperature drop delay time for each cooled radiofrequency probe, wherein expected temperature drop delay time is calculated from a recorded activation time of each cooled radiofrequency probe.
