The first-in-human trial of a new miniaturized leadless pacemaker implanted directly inside the heart found the Medtronic Micra transcatheter pacing system (TPS) safe and effective in patients with a slow heart rhythm. Early performance results from the international Micra Transcatheter Pacing Study were presented at Heart Rhythm 2015, the Heart Rhythm Society’s 36th annual scientific sessions, May 13-16 in Boston.
