CINCINNATI, Ohio — AtriCure Inc. in suburban Cincinnati, Ohio, has received U.S. Food and Drug Administration approval to sell a disposable medical device that uses extreme cold to treat abnormal heart rhythms.
The Cryo1 system can be used to  freeze tiny amounts of heart tissue to disrupt bad electrical impulses that cause atrial fibrillation – a misfiring of the top chambers of the heart — and other heart arrhythmias.
In addition, Dr. Niv Ad, the chief cardiac surgeon at Inova Fairfax Hospital in Falls Church, Va., used the Cryo1 ablation probe to successfully treat a patient through a minimally invasive procedure, AtriCure said.
AtriCure in West Chester makes devices and systems to do cardiac ablation procedures. The company’s shares fell 5 cents to $1.32 Friday on the NASDAQ Stock Market.
