Abstract
An apparatus and method for treating atrial fibrillation with ablation therapy in which a stent is deployed within a pulmonary vein and tissue surrounding the stent is ablated with radiofrequency energy to stop discharges from ectopic foci in the vein from reaching the left atrium. The deployed stent can then be left in place to prevent stenosis of the vein as well as allowing repeat ablation procedures as needed.
