PMA (Premarket Approval) is the FDA’s most rigorous regulatory pathway, required for Class III medical devices, which support or sustain human life, are implanted, or present a potential unreasonable risk of illness or injury.
Unlike a 510(k), the PMA process does not rely on substantial equivalence. Instead, it demands independent evidence of safety and effectiveness, typically through extensive clinical trials.
Use the PMA pathway when:
- No predicate device exists and the risk profile is high
- The device is life-sustaining, life-supporting, or intended for a critical indication
- FDA requires a high level of scrutiny before the device can be marketed
PMA is the most resource- and time-intensive FDA submission route, but it’s necessary when public health and safety require comprehensive evidence before approval.
