Micra™ is the newest and smallest in our line of pacemakers, approved for use in the
United States by the FDA in April 2016.
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.
Less invasive — Micra is placed in the heart via a vein in the leg, thus 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.2
For most patients, the Micra design translates to fewer medical complications and fewer
post-implant activity restrictions.
The Micra design incorporates certain time-tested, valuable features from the Medtronic
line of pacemakers:
Permits you to safely undergo magnetic resonance imaging (MRI), a diagnostic tool
doctors use to "see" inside the body
Adjusts your heart rate automatically by sensing changes in your body related to your
activity level and adjusting your heart rate accordingly
Features an estimated battery longevity of 12 years
Is Micra the right pacemaker for all patients?
No. Micra is intended for patients who need a single chamber pacemaker (also known
as a ventricular pacemaker, or VVIR). Talk to your doctor about the suitability, benefits,
and risks of Micra for you.
How is Micra placed into my heart?
Your doctor will insert a "straw-like" catheter into a vein in your upper thigh and use the
catheter to move Micra into the right ventricle of your heart. The catheter is then
Are MRI scans okay with my Micra?
Micra was designed, tested, and approved to be used safely with MRI scanners. You
can undergo an MRI scan as long as patient eligibility requirements are met. Your
pacemaker ID card specifies the implanted device model. If your doctor has questions
about scanning eligibility, he or she should contact a Medtronic representative or
Medtronic Technical Services.
Will items containing magnets affect my Micra?
Maybe. We recommend keeping items containing magnets at least 6 inches away from
an implanted pacemaker. This includes mobile phones, magnetic therapy products,
stereo speakers, and handheld massagers. We do not recommend putting a mobile
phone in your shirt pocket or using magnetic mattress pads and pillows.
Is it safe to go through an airport metal detector?
Yes, you can safely go through airport security with this device.
Are household appliances safe to use?
Yes, household appliances that are properly maintained and in good working order are
safe. This includes microwave ovens, major appliances, electric blankets, and heating
Can I exercise, resume my regular activities?
Yes, you should be able to return to your usual activities, as long you do not exceed
your fitness level. Discuss questions about specific activities with your doctor.
Does Micra last forever?
No, Micra has a battery and the battery life depends on your heart condition. The
estimated average longevity is 12 years.3 Individual patient experience may vary. Your
doctor will check on the battery when you come in for a checkup.
What happens when the Micra battery runs low?
Micra is designed to provide options when a new device is needed. It may be turned off
and a new Micra or a traditional system may be implanted. The Micra also offers a
retrieval feature to enable retrieval, when possible. Your doctor will determine what is
best for you.
How often will I need to visit the doctor after Micra is implanted?
Your doctor will decide how often he or she wants to see you. Typically, your first followup appointment is one month after implant, with additional follow-ups every 6-12
