ABSTRACT:
A system and method for treatment of paroxysmal atrial fibrillation by destruction of conductive pathways between the pulmonary veins and the left atrium. A stent is delivered by catheter to the left atrium and to the ostium of a pulmonary vein to be treated. The stent is positioned in the pulmonary vein and is deployed to engage and support the pulmonary vein. The stent prevents stenosis of the pulmonary vein as a result of ablation of tissue. The ablation is produced by a coating of a biologically active material on the stent which destroys tissue or slows electrophyisiologic conduction through the tissue. Alternatively, ablation is performed using RF energy, cryoablation, laser energy, or other ablation techniques.
