ABSTRACT:
A catheter-based method for coronary sinus mapping, pacing, and ablation, wherein a flexible electrode catheter, having a tip electrode with suspension structure, is pre-shaped to snugly fit into the coronary sinus, so that the tip electrode is positioned into the sinus; the distal section is deflected to expose a predetermined plurality of electrodes; and RF energy is then applied to the coronary sinus tissue through the electrodes to cause activation mapping, and/or ablation.
