Abstract
Ablation instruments and techniques are disclosed for accessing portions of the heart wall via the coronary sinus. While shielding the major portion of the sinus and/or the circumflex coronary artery from ablative energy, the present invention provides access to the heart wall to treat atrial fibrillation. In particular, the present invention provides instruments and methods for forming transmural lesions in the left atrium, such as the so-called “left isthmus block,” from within the coronary sinus.
