St. Jude Medical Inc. (NYSE:STJ) won pre-market approval for 2 next-generation cardiac ablation systems this month, the Therapy Cool Path Duo and Safire Blu Duo catheters.
Both ablation systems use radiofrequency energy to freeze small areas of faulty cardiac tissue in patients with typical trial flutter, a type of arrhythmia in which patients experience abnormal heart rhythms or an abnormally fast heartbeat in the upper chambers of the heart.
