How to Find and Compare FDA 510(k) Predicate Devices
Find possible FDA 510(k) predicate devices by product code and intended use, then compare technological characteristics, validation evidence, and predicate chains.
Direct answer
Start with the FDA product code and intended use, identify recently cleared devices in the same classification, and then compare indications, technological characteristics, performance evidence, and the predicates each clearance cited. A search result is a research candidate, not a legal conclusion that a device is an appropriate predicate.
Search 510(k) predicate evidence →Start with classification, not a trade-name match
FDA says searching by product code is usually the most effective way to find recently cleared predicate candidates. Manufacturer and trade-name searches can help, but names change and the 510(k) database preserves original applicant and trade-name information.
Use the intended use and indications for use to narrow the set. A similar product name is not enough: the comparison has to account for the use, design, energy, materials, performance, safety, labeling, standards, and other applicable characteristics.
- Confirm the product code and device classification.
- Search recent clearances in that product code and adjacent classifications.
- Read the indications for use and intended-use language before comparing features.
- Record the primary predicate, any additional predicates, and reference devices separately.
Compare the evidence FDA actually reviewed
FDA's 510(k) content guidance describes a side-by-side comparison of the subject and predicate devices. The relevant dimensions can include intended use, design, materials, performance, safety, effectiveness, labeling, biocompatibility, and standards.
Performance evidence varies with the device. A summary may describe bench, engineering, design-verification, human-factors, animal, or clinical testing. Keep each result attached to its analysis unit and study design; do not pool unlike metrics across devices.
- Compare intended use before performance metrics.
- Separate bench, retrospective, prospective, reader, and standalone studies.
- Preserve sample size, task, endpoint, population, and comparator with every metric.
- Follow the predicate chain to see what earlier clearances each candidate relied on.
What Constat adds to the FDA record
FDA remains the authoritative source. Constat turns public summaries into source-linked fields so a researcher can search intended use, see cited predicates, compare disclosed validation designs, and return to the official database record and PDF.
Constat does not choose a predicate or replace a submission-specific regulatory assessment. It reduces document-retrieval and comparison work while keeping omissions visible as not stated.
Questions researchers ask
What is a 510(k) predicate device?
A predicate is a legally marketed device used in a 510(k) submission to support a substantial-equivalence comparison. The subject and predicate devices do not have to be identical.
Can the newest device automatically be used as a predicate?
No. Recent clearances are useful research candidates, but predicate suitability depends on intended use, technological characteristics, legal marketing status, and the submission-specific comparison.
What should a predicate comparison include?
At minimum, compare intended use, indications, technological characteristics, performance evidence, labeling, applicable standards, and the predicate chain disclosed in the public record.
