MINNEAPOLIS & NEW ORLEANS--(BUSINESS WIRE)--Clinical data on the use of the CVRx® Rheos® System show Rheos Therapy significantly improved heart structure and function in patients with high blood pressure. Peter W. de Leeuw, professor of medicine and hypertension at the University of Maastricht in The Netherlands, presented the data on November 11 (oral presentation #4426) at the American Heart Association (AHA) Scientific Sessions 2008 in New Orleans. In addition, data from a pre-clinical study indicate that, after receiving Rheos Therapy, canines with heart failure were less likely to be induced into lethal ventricular heart rhythms, a risk factor for sudden cardiac arrest (poster session #2415).
