Micra 

Transcatheter Pacing System

  • Micra Transcatheter Pacing System

Clinical Evidence

Primary prespecified safety, effectiveness, and long-term safety objectives were met (n = 726)1,2

  • 96% of patients experienced no major complications by 12 months follow-up2
    • 0 dislodgements or systemic infections
    • Low (0.4%) revision rate
  • Pacing thresholds remained low and stable pacing thresholds through 12 months1
    • Yielding an estimated battery longevity on average of 12.1 years

Real-world experience reinforces safety and long-term performance of Micra3

  • Data includes 1,817 enrolled patients at 179 centers in 23 countries 
  • High implant success rate (99.1%)
  • Major complication rate detail through 12 months (2.7%)
    • Perforation rate (0.44%)
    • Infection rate (0.17%); no device-related infection or device removal due to infection
    • Dislodgement rate (0.06%)

Lower rate of complications

  • 63% fewer major complications than traditional pacemakers*3

Pacing Capsule

*

Historical cohort comprised of 2,667 patients from 6 trials of commercially available technology. (HR: 0.46, 95% CI: 0.30-0.72; P-value: < 0.001). To adjust for difference in patient populations, propensity matching to a subset of the historical control confirmed a reduction in major complications with Micra.
