ThermoCool and EZ Steer Thermo Cool get FDA approval to treat rogue cells

Atrial fibrillation affects more than 2 million Americans, causing debilitating fatigue for some and raising the risks of strokes, heart attacks and death, according to the U.S. National Institutes of Health. The heart-ablation market may reach $2 billion in annual sales by 2011, said Rick Wise, a Leerink Swan & Co. analyst in New York, in a note to clients last year. Worldwide
