catheter ablation
pulmonary vein isolation
permanent atrial fibrillation


This clinical investigation evaluates the feasibility of the Rodeo Micro Mapping Catheter in combination with cryoablation ssystem (sclerotherapy of muscle tissue of the heart by freezing) in patients with atrial fibrillation (permanent atrial fibrillation excepted).

Further aims of this study are the evaluation of safety of the device and average procedure and fluoroscopy times.
