The World’s Smallest Pacemaker

Bradycardia is a condition characterized by a slow or irregular heart rhythm, usually fewer than 60 beats per minute (normal heart rate is 60 — 100 bpm). At this rate, the heart is unable to pump enough oxygen-rich blood to the body during normal activity or exercise, causing dizziness, fatigue, shortness of breath or fainting spells.

Pacemakers, the most common way to treat bradycardia, help restore the heart's normal rhythm and relieve symptoms by sending electrical impulses to the heart to increase the heart rate.

Unlike most pacemakers that are placed in the patient's chest with leads running to the heart, Micra is implanted directly into the patient’s heart. The miniaturized, fully self-contained pacemaker delivers the most advanced pacing technology available to patients via a minimally invasive approach.

  • Less invasive — Micra is placed in the heart through a vein in the leg, which means no chest incision, scar, or bump that results from conventional pacemakers.
  • Self-contained — Micra is completely self-contained within the heart. It eliminates potential medical complications¬†arising from a chest incision and from wires running from a conventional pacemaker into the heart.
  • Small — Micra is 93% smaller than conventional pacemakers, about the size of a large vitamin capsule and weighs the same as a penny (2 g).
  • Safe — Safely undergo magnetic resonance imaging (MRI), a diagnostic tool doctors use to “see” inside the body
  • Advanced — Adjusts your heart rate automatically by sensing changes in your body related to your activity level and adjusting your heart rate accordingly
