CINCINNATI, Ohio — AtriCure Inc. in suburbanÂ Cincinnati, Ohio, has received U.S. Food and Drug Administration approval to sellÂ a disposable medical device that uses extreme cold to treat abnormal heart rhythms.
The Cryo1Â system can be used to Â freeze tiny amountsÂ of heart tissue to disruptÂ bad electrical impulses that cause atrial fibrillation –Â a misfiring of theÂ top chambers of the heart — and other heart arrhythmias.
In addition, Dr.Â Niv Ad, the chief cardiac surgeon at Inova FairfaxÂ Hospital in Falls Church, Va., used the Cryo1 ablation probe to successfully treat a patient through a minimally invasive procedure, AtriCure said.
