Medical Devices: 510(k) Premarket Notification

Identify the device’s intended use, classification regulation and product code. A class designation by itself does not resolve all premarket duties. Some devices are exempt from notification within defined limitations; others require a different pathway. Exemption from 510(k) does not automatically remove quality-system, labeling or postmarket responsibilities. FDA notification overview.

Substantial equivalence is evaluated against a legally marketed device eligible to serve as a predicate. The comparison addresses intended use and technological characteristics, with evidence needed when differences raise relevant questions. Similar appearance or a competitor’s registration number is not sufficient. The predicate choice must fit the regulatory comparison actually being made. FDA substantial-equivalence guidance.

Performance testing depends on the device, technology, risks and intended use. Bench, software, biocompatibility, electrical or clinical information may be relevant in particular cases; there is no universal test package for all 510(k)s. The submission should explain how the evidence supports the specific comparison, including differences that could affect safety or effectiveness. FDA guidance.

Subpart E addresses information submitted in a notification and related provisions. FDA reviews the comparison and can request additional information before deciding substantial equivalence. Submission receipt, establishment registration and an electronic tracking number do not mean the device is cleared. Marketing claims must reflect the actual decision and authorized intended use. Part 807.

Changes to an existing device require evaluation of whether a new notification or another submission is necessary. That decision should consider the specific modification and applicable FDA policies rather than relying on an earlier clearance indefinitely. Manufacture and distribution also remain subject to the other device requirements that apply to the firm and product. FDA 510(k) explanation.

Retain the classification analysis, exemption rationale if any, predicate comparison, testing rationale and FDA correspondence. Compare the device actually distributed with the cleared configuration and labeling. Use the public FDA resources to locate the governing pathway and product-specific guidance, then record unresolved technical questions before finalizing a submission strategy.
