Monitoring tissue temperature while using an irrigated catheter

A computer software product comprising a non-transitory computer-readable medium having computer program instructions recorded therein, which instructions, when read by a computer, cause the computer to:

• model physical parameters representative of a probe in proximity to body tissue during an ablation procedure performed by the probe on the body tissue by generating calculated non-ablative values of a subgroup for the non-ablation stage and generating calculated ablative values of the subgroup for the ablation stage;
• measure a subgroup of the physical parameters through at least one of the sensor and the electrode during the non-ablation stage of the ablation procedure so as to generate measured non-ablative values of the subgroup;
• measure the subgroup of the physical parameters through at least one of the sensor and the electrode during the ablation stage of the ablation procedure so as to generate measured ablative values of the subgroup;
• and
• compare the measured non-ablative values with the calculated non-ablative values, and compare the measured ablative values with the calculated ablative values, so as to generate optimal values of the physical parameters.
