Meet Micra, our leadless pacemaker

Micra™ is the world's smallest pacemaker.1 Unlike most pacemakers that are placed in a patient's chest with leads running to the heart, Micra is a leadless pacemaker because it's implanted directly into the heart.

  • Less invasive — Micra is placed in the heart via a vein in the leg. The procedure requires no chest incision and, unlike conventional pacemakers, does not create a scar or bump under the skin.
  • 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.2

For most patients, the Micra design translates to fewer medical complications and fewer post-implant activity restrictions. 

Patient testimonials


Tim lived with a traditional pacemaker for 18 years, but due to pre-existing health conditions, his device was causing him pain. His doctor told him about another option, a leadless pacemaker, which allowed him to focus on his life and his family instead of his pain and his condition.



After a series of fainting episodes halted Ross' running routine, he knew it was time to talk to his doctor. Together, they decided a leadless pacemaker was the best way to keep him on the trails.



For years, Janet dealt with fainting spells from bradycardia but had no idea the problem was with her heart. Once doctors understood her condition, they quickly recommended a leadless pacemaker.

How to talk with your doctor

Here are some things you might discuss when talking to your doctor.

  • Ask your doctor if a Micra leadless pacemaker is an option for you.
    While nearly half of all pacemaker patients may be eligible for a leadless pacemaker, it’s intended for specific pacing needs.3
  • Talk with your doctor about the potential benefits and risks of a leadless pacemaker.
    There are many potential benefits to a leadless pacemaker, including no visible bump or scarring on your chest and a lower risk of complications.4 However, like all pacemakers, there are some risks associated. Your doctor can discuss how you can continue to enjoy your everyday activities and hobbies. 
  • Discuss next steps.
    If you and your doctor decide Micra is right for you, ask about next steps.
