The next generation of the world’s smallest pacemakers1
The Micra™ AV2 and Micra™ VR2 have projected median longevities of nearly 16–17 years, meaning more than 80% of patients will only need one Micra™ device for life.2
These innovations required zero change to the device size.
Micra™ AV2 automatically customizes AV synchrony settings for each patient, reducing the need for manual programming by more than 50% compared to Micra™ AV.2
The smarter algorithms also improve automatic AV synchrony at faster heart rates between 80–100 bpm,2 and the upper tracking rate limit is now 135 bpm.
The updated delivery system now has a rounded catheter tip with more surface area to decrease tip pressure during device implant.3
Micra™ AV2 and Micra™ VR2 devices are implanted with the same streamlined procedure that has been utilized by nearly 10,000 trained Micra™ physicians worldwide.5
Micra™ AV2 and Micra™ VR2 provide an unmatched leadless pacing experience for bradycardia patients.
With improved battery longevity and smarter algorithms, most patients will only need one device for life.2

The 105 cm long delivery system has a handle that controls deflection and deployment of the Micra™ pacing capsule. There are five key components:
The Micra™ introducer sheath enables smooth vessel navigation with a lubricious hydrophilic coating and silicone oil-coated dilator tip. It has a 23 Fr inner diameter and 27 Fr outer diameter. There are three key components:
Chinitz, et al. Heart Rhythm. 2023.
The first prospective multicenter study of Micra™ AV concludes that it significantly improves quality of life in patients with AV block and normal sinus function.
AV synchrony remained stable through three months and there were no system upgrades to dual-chamber systems.
Crossley, et al. J Cardiovasc Electrophysiol. 2023.
Patients treated with Micra™ VR experience significantly fewer complications, reinterventions, infections, and heart failure hospitalizations through three-years compared to patients receiving a traditional transvenous pacemaker.
