In this image taken May 23, 2012, Dr. Manesh Patel, an interventional cardiologist at Duke Heart Center, poses for a photo in the lab at Duke University Hospital in Durham, N.C. Patel is participating in a research study of a way to treat high blood pressure by threading a catheter to the kidney and zapping nearby nerves that fuel blood pressure. Duke is one of more than 60 hospitals taking part in the clinical trial of what’s called renal denervation. (AP Photo/Gerry Broome) less
