Frequently asked questions about Micra

Is Micra for every patient?

Micra is intended for patients with specific pacing needs. Talk to your doctor about the potential benefits and risks of Micra.

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 removed. 

Are MRI scans OK 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 pads.

Can I exercise or resume my regular activities?

Most patients are able to return to their usual activities. Talk to your doctor about any limitations you may have as a result of getting a Micra device, and discuss questions about specific activities.

Does Micra last forever?

No, Micra has a battery and the battery life depends on your heart condition. The estimated average longevity is between 8 and 13 years.1,2 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?

When a new device is needed, the Micra device may be simply turned off before a new leadless or traditional pacemaker system is implanted. Your doctor will determine what is best for you.3,4

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 follow-up appointment is one month after implant, with additional follow-ups every 6–12 months.
