MicroPort® is dedicated to keeping cardiac patients as people – outside of hospitals and living life to the fullest. With its long-lasting devices, our Cardiac Rhythm Management portfolio keeps life beating stronger and longer for over 400 000 people worldwide.*

Longevity in Cardiac Care

Committed to providing the highest quality of care to our patients, our devices excel at predicting longevity and helping reduce replacements and re-interventions. Let’s hear Dr. De Sousa’s perspective on longevity, a cardiac electrophysiologist who has been implanting MicroPort® devices for nearly 30 years now.

13 years1 longevity
with remote monitoring and full feature set ON

Greatest projected longevity with up to 42% additional battery life compared to other devices up to 14 cc2.


  • Up to 22 minutes of EGM with pre-event EGM recordings
  • Continuous Sleep Apnea Monitoring
  • MV and G sensors for optimal rate adaptation

Thanks to an excellent longevity with remote monitoring, you can provide continuous and efficient patient care.


Alizea & Eno

The Best ratio Longevity per Volume2

Optimized electronic placement, low intrinsic consumption and ellipse shape ensure no dead space, allowing MicroPort® to achieve the ideal ratio between size, shape and longevity for its latest pacemaker ranges.

  • Eno™ is the world’s smallest transvenous pacemaker with the best longevity per cc
  • Alizea™ and Eno™ dual chamber transvenous pacemakers have the best projected longevity per cc

Microport®’s ideal ratios

Comparison across manufacturers based on 100% pacing in atrial and ventricular chambers**

** Conditions: DDDR mode 100 % A&V pacing 60min-1, 2.5V, 0.4ms, 500 Ω, sensor G ON, EGMs ON
*** Conditions: DDD mode 100 % A&V pacing 60min-1, 2.5V, 0.4ms, 500 Ω, sensor G OFF, EGMs ON


Unparalleled longevity4

Our devices incorporate advanced technology that withstands the test of time. Having the lowest current drain and a large battery capacity, MicroPort® excels in predicted longevity compared to other devices, saving patients from early replacements and alleviating the burden on healthcare systems.5,6
