PULMONARY VEIN ARRHYTHMIA DIAGNOSTIC DEVICE AND METHOD FOR USE

摘要

Devices and methods for testing a pulmonary vein to determine whether or not ablation would be effective in terminating atrial fibrillation. The devices and methods include a catheter having an expandable balloon (2) attached to the distal end of the catheter. The balloon has pores (6) on the distal end of the balloon for administering a fluid into the target pulmonary vein (3). The fluid inhibits the electrical impulses generated by the target pulmonary vein. Once the electrical impulses of the target pulmonary vein have been inhibited it can be determined whether or not the atrial fibrillation continues to occur.
