摘要：
Cardiac ablation is carried out by introducing a catheter into the left atrium, extending a lasso guide through the lumen of the catheter to engage the wall of a pulmonary vein, and deploying a balloon over the lasso guide. The balloon has an electrode assembly disposed its exterior. The electrode assembly includes a plurality of ablation electrodes circumferentially arranged about the longitudinal axis of the catheter. The inflated balloon is positioned against the pulmonary vein ostium, so that the ablation electrodes are in galvanic contact with the pulmonary vein, and electrical energy is conducted through the ablation electrodes to produce a circumferential lesion that circumscribes the pulmonary vein.
