ABSTRACT:
An ablative apparatus that can be used to treat atrial fibrillation and other cardiac arrhythmias by ablating cardiac tissue is disclosed. When the distal end of the apparatus reaches the tissue to be ablated, an ablation probe driven by a transducer is vibrated. Scratching the tissue with abrasive members, the vibrating ablation probe is capable of mechanically ablating tissues. This mechanical ablation may be utilized to penetrate epicardial fat, thereby exposing the underlying myocardium. The ablative apparatus may then be used subject the exposed myocardium to mechanical ablation, cryoablation, ultrasonic ablation, and/or any combination thereof.
