One with heart.

Empower AF Risk Management. Minimize ventricular pacing for SND and AVB patients. Screen and Monitor for Sleep Apnea.
World’s smallest transvenous pacemaker.1
1.5 T and 3 T full body MR conditional.



Dramatically reduces unnecessary RV pacing in all pacemaker patients, including AV block patients.



Sleep Apnea Monitoring measures respiration pauses and reduction in respiration.



Making MRI scans easy and safe for pacemaker patients.


Dual Sensor

Designed to physiologically modulate heart rhythm by combining Accelerometer and Minute Ventilation sensors.

AF risk management

Ventricular Pacing reduction

  • Protect patients from developing AF2,3,4

Atrial prematurity detection

  • Detect AF with 96% sensitivity and 96% specificity5

Sleep Apnea screening

  • Reveal the silent cause of AF6,7

Control AF recurrence risk 

  • Long-term sleep apnea monitoring helps prevent resurgence of AF 8,9,10

φ Intelligence

Physio-inspired design

Mimics the natural way the heart works and minimizes artificial intervention.

Wave to wave thinking

Permanent adaptive strategy for real time decisions that respond to all levels of patient activity, day and night, evolving and learning with the patient.

Symbiotic programming

Programming is driven only by hemodynamic needs. All therapeutic features are independently programmable, designed to work simultaneously together with no conflict.

Ratio Design

8 cc

  • Smaller incision & reduced pocket size
  • Boosts psychological adoption for patients

Ellipse Shape

  • Natural lead wrap around
  • Facilitates insertion and lead connection

12 years longevity* in 8 cc 

  • Avoid complications due to risky replacement procedures11,12

Best longevity per cc

  • MicroPort CRM’s technology brings together size and longevity.
  • 12 years longevity* in 8 cc.


Visit. Scan. Go.
Automatic switch in and out of MRI mode upon detection of MR field.
