摘要：
The present invention provides devices and methods for the treatment of atrial fibrillation. In one embodiment method for treatment of atrial fibrillation is provided that includes positioning a sheath catheter having a deflectable distal end segment in the left atrium of a heart, orienting said sheath catheter such that an ablation instrument can be delivered through the sheath catheter to a position proximal to a first pulmonary vein, activating the ablation instrument to form a circumferential lesion around the first pulmonary vein, repositioning the sheath catheter by deflecting the distal end segment to another orientation, and activating the ablation instrument to form a circumferential lesion around at least one additional pulmonary vein.
