FDA 510(k): The Pathway for Energy-Based Devices into the US Market
The US Baseline
FDA classes devices into three risk tiers: Class I (mostly exempt), Class II (most go through 510(k) premarket notification) and Class III (PMA approval). Aesthetic energy devices are mostly Class II, marketed via 510(k): demonstrating substantial equivalence to a legally marketed predicate device.
Key 510(k) Concepts
- Product codes: FDA assigns by function (e.g., GEX hair-removal lasers, ILA IPL), determining the review division and guidance.
- Substantial equivalence: same intended use and technology characteristics, or no new questions of safety and effectiveness.
- Timeline: statutory 90-day review (often longer in practice), far cheaper than PMA.
- PMA: novel mechanisms without suitable predicates require clinical-data Class III approval — years and an order of magnitude more cost.
Common Misconceptions
- “Cleared” ≠ “approved”: cleared = 510(k); approved = PMA. Marketing copy often blurs them — check the letter’s pathway.
- Registration ≠ clearance: establishment registration and listing are not marketing authorization.
- Predicate chains: predicates must themselves be legal; “ghost predicates” are an FDA enforcement focus.
What Buyers Should Do
US buyers verify FDA clearance via the 510(k) database (search by firm or product, check the K-number letter). LEIJEX advances registrations per target market — status available from the compliance page and sales team.
FAQ
Can a device without a K-number be used in the US?
Not for human treatment, except devices exempt from clearance. Ask for the K-number and verify it on the FDA database.
How long does 510(k) take?
Statutory review is 90 days; preparing performance, biocompatibility, software and electrical-safety data often takes months to a year-plus — plan in years.
