Micra leadless pacemakers for bradycardia (slow heart rate)

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.

Micra VR2 and AV2 transcatheter pacing system devices
  • Smallest pacemaker — Micra is 93% smaller than conventional pacemakers, about the size of a large vitamin capsule.2
  • Less invasive — The procedure requires no chest incision and, unlike conventional pacemakers, does not create a scar or bump under the skin. 
  • Fewer restrictions — For most patients, the Micra design translates to fewer medical complications and fewer post-implant activity restrictions.

Patient testimonials

These patient testimonials are based on each individual’s experience. Not all patients will experience similar results. Please talk to your doctor about your condition and the risks and benefits of this therapy.


After years of experiencing heart issues, including a transient ischemic attack (TIA) and complete heart block, Mekaela and her family found answers and peace of mind with the Reveal LINQ™ ICM and the Micra™ AV pacemaker.



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.  


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.

  • 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.
