Abstract: The invention provides apparatus and methods for mapping conduction pathways and creating transmural lesions in the heart wall for the treatment of atrial fibrillation. The apparatus may include at least one epicardial ablation probe having a plurality of electrodes for creating a transmural lesion. The apparatus and method facilitate the formation of a transmural lesion which electrically isolates the pulmonary veins from the surrounding myocardium without cutting or penetrating the pericardial reflections.
