FDA 510(k) Premarket Notification

Most Class II medical devices enter the US market through the 510(k) pathway rather than the more rigorous PMA (Premarket Approval) process. A 510(k) must demonstrate "substantial equivalence" to a predicate device — meaning the new device has the same intended use and the same or similar technological characteristics, and that any differences do not raise new safety or effectiveness questions.

The 510(k) submission must include: device description and intended use; predicate device identification; comparison of technological characteristics; performance testing data demonstrating equivalence; and proposed labeling. FDA review takes an average of 3-6 months under the MDUFA performance goals. Common 510(k) deficiencies include inadequate predicate comparison, insufficient performance testing, and labeling that expands the intended use beyond the predicate. Document intelligence tools enable regulatory affairs teams to rapidly review 510(k) submissions for completeness, identify gaps against FDA guidance documents, and compare performance data across multiple predicate devices.
