The Micra TPS attaches to the heart with small tines, delivering impulses with an electrode at one end. The device doesn't require a "pocket" under a patient's skin like traditional devices and it's completely concealed from view. What's more, this tiny pacemaker adjusts the impulse based on a patient's activity level automatically. It's also approved for use during full-body MRI scans, so patients will still have access to detailed medical imaging processes should the need arise.

During clinical trials, Medtronic says the Micra TPS was successfully implanted in over 99 percent of patients with no reported instances of it moving out of place. 96 percent patients didn't experience any complications either, 51 percent lower than the numbers for more traditional pacemakers. The company also notes that over 98 percent of patients exhibited "low and stable" pacing after six months, a rate at which the Micra TPS could last for more than 12 years.
