In this undated image provided on Saturday Aug. 29, 2015 by Mount Sinai Hospital in New York shows Dr Vivek Reddy as he checks the screen while doing a surgery to implant the new tiny wireless pacemaker at the Mount Sinai hospital in New York . Unlike traditional pacemakers — which need a generator and wires and are implanted via surgery — the new pacemaker is a wireless tiny tube that can be attached to the right side of the heart using a catheter inserted through the leg.
