Ablation stent for treating atrial fibrillation
First Claim
Patent Images
1. A method for treating atrial fibrillation, comprising:
- introducing a stent into the left atrium of a patient;
deploying the stent into a pulmonary vein;
applying radiofrequency energy to the deployed stent in order to ablate surrounding tissue and stop discharges from ectopic foci in the vein from reaching the left atrium; and
, leaving the stent in place in order to prevent stenosis of the vein.

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.

12. An apparatus for treating atrial fibrillation, comprising:
-
a stent catheter having a stent mounted thereon for deployment in a pulmonary vein, the catheter including a balloon at its distal end for expanding the stent within a pulmonary vein; and
,an electrode for transmitting radiofrequency energy to the deployed stent in order to ablate surrounding tissue and stop discharges from ectopic foci in the vein from reaching the left atrium.
