TIMING SYSTEM FOR USE DURING ABLATION PROCEDURE

A timing system during an ablation procedure having a time to isolation includes an automated timer that receives a first time setting. The first time setting provides a maximum time that the ablation procedure can continue without reaching the time to isolation. A catheter system including the timing system can also include a control system that is configured to automatically stop the ablation procedure if the first time setting expires without reaching the time to isolation. The operator can input the first time setting via a graphical display of the catheter system. The automated timer can generate an expiration signal if the first time setting expires without reaching the time to isolation. The automated timer can further receive a second time setting from the operator that provides a maximum time that the ablation procedure can continue after reaching the time to isolation.
