MONITORING AND TRACKING BIPOLAR ABLATION
First Claim
1. A method for treating abnormal cardiac electrical activity, comprising the steps of:
- providing a probe having first and second ablation electrodes disposed on a distal portion of the probe and a sensing electrode disposed between the first and second ablation electrodes;
bringing the probe into contact with a target tissue in a heart of a subject;
applying energy through the first and second ablation electrodes to ablate the target tissue along an ablation path;
while performing the step of applying energy, monitoring cardiac electrical activity using the sensing electrode to detect the cardiac electrical activity;
making an observation that the cardiac electrical activity is no longer detectable by the sensing electrode; and
responsively to the observation terminating the step of applying energy.

Abstract
Methods and systems treat abnormal cardiac electrical activity employing a probe having first and second ablation electrodes disposed on a distal portion of the probe and a sensing electrode disposed between the first and second ablation electrodes, bringing the probe into contact with cardiac tissue, and applying energy through the first and second ablation electrodes to ablate target tissue along an ablation path, monitoring cardiac electrical activity using the sensing electrode to detect the cardiac electrical activity. After making an observation that the cardiac electrical activity is no longer detectable by the sensing electrode, energy application is terminated.
