FDA 510(k) Similar-Device Research Workflow Before Predicate Review

When a team is about to ask a consultant about predicate strategy, a raw FDA database search is not enough. The useful output is a dated similar-device workflow with search terms, product-code clues, K-number shortlist, intended-use notes, technology differences, and open review questions.

The workflow does not select a predicate or prove substantial equivalence. It gives qualified reviewers a clean evidence trail to evaluate.

For founders and first RA/QA hires who need a similar-device shortlist before a 510(k) consultant call.

Pre-production brief

Blocked decisionWhich records are worth qualified predicate or comparison review.
Useful artifactDated similar-device shortlist with source URLs, search terms, comparison notes, and open questions.

Reviewer workflow

  • Start from the device description and intended use, then search candidate product-code clues.
  • Query the 510(k) database by product code, device name, applicant, and decision date where relevant.
  • Record K-number, product code, applicant, device name, indications, and source URL for each candidate.
  • Compare intended use and technology in plain language before asking about predicate fit.
  • Route predicate and substantial-equivalence questions to qualified RA/QA or a consultant.

Same-looking devices still need review

A product can look similar in a database and still differ in intended use, patient population, operating principle, software function, materials, sterilization, cybersecurity, or labeling.

The workflow should preserve those differences instead of hiding them. A shortlist is useful only if reviewers can see what is the same, what is different, and what remains unverified.

What TrueMedDevice can prepare

TrueMedDevice can prepare the search log, candidate product-code notes, K-number shortlist, comparison table, source ledger, and open predicate questions.

Qualified RA/QA, consultants, and FDA decide predicate strategy, pathway, and substantial equivalence.

Source ledger

FDA 510(k) clearances database

What it can tell you

Public 510(k) records, K-numbers, applicant names, decision dates, and summary links.

What it cannot decide

Whether one record is a suitable predicate for a specific new device.

FDA product-code classification database

What it can tell you

Candidate product-code and regulation clues to structure similar-device research.

What it cannot decide

Final classification, product code, pathway, or submission type.

FDA, how to find and effectively use predicate devices

What it can tell you

FDA's public explanation of predicate-device research and predicate use.

What it cannot decide

Predicate adequacy or substantial equivalence for a specific device.

openFDA

What it can tell you

Programmatic access patterns for FDA public datasets when research needs scale beyond manual lookup.

What it cannot decide

The meaning or regulatory significance of a search result without review.

Frequently asked questions

Does finding similar 510(k) records mean I found my predicate?

No. It means you found candidate records for review. Predicate suitability requires qualified assessment of intended use and technological characteristics.

What should I bring to a consultant from the search?

Bring search terms, product-code clues, K-numbers, source URLs, comparison notes, and the questions you could not answer from public records.

Can openFDA replace a consultant?

No. openFDA can help retrieve public data, but it does not interpret predicate fit or submission strategy.

Need a similar-device shortlist before the consultant call?

TrueMedDevice can organize FDA search terms, candidate K-numbers, comparison rows, and open predicate questions into one packet.
