Abstract
The invention provides apparatus and methods for mapping conduction pathways and creating 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 lesion. The apparatus and method facilitate the formation of a lesion which electrically isolates the pulmonary veins from the surrounding myocardium.
Claims11
A method of ablating tissue from an epicardial location, comprising the steps of:
- providing an ablating device having an ablating element, the ablating device having a locking mechanism for locking a part of the ablating device to another part of the ablating device;
- positioning the ablating device around a portion of a patient's heart with the ablating element positioned against an epicardial location;
- locking the locking mechanism so that the ablating device forms a closed loop around a portion of the patient's heart with the ablating element positioned at the epicardial location and
- ablating tissue with the ablating device.
