The FDA approved Jan. 21 Medtronic's Micra AV, the world's smallest pacemaker with atrioventricular synchrony, according to the company.
The device is designed to treat patients with AV block, a condition in which electrical signals between chambers of the heart are impaired.

Use of the Micra has shown a 63 percent decrease in major complications compared to traditional pacemakers, according to Larry Chinitz, MD, director of NYU Langone's heart rhythm center.
