510(k) Predicate Finder
Find potential predicate devices for your 510(k) submission. Enter a K-number to find all clearances with the same product code, a three-letter product code to browse clearances directly, or search by device name.

Neurology
The Implanted Neuromuscular Stimulator is a surgically implanted device that delivers electrical impulses to motor nerves or muscles to restore or augment functional movement in patients with paralysis or neuromuscular disorders. It is classified as a Class 3 device (highest risk), requiring Premarket Approval (PMA); a call for PMAs was issued by July 13, 1999, per 64 FR 18329. The product code is GZC under regulation 21 CFR 882.5860 in the Neurology specialty. The implant flag is active for this device.

What is a Predicate Device?
A predicate device is a legally marketed device that a new 510(k) applicant uses to demonstrate substantial equivalence. The FDA's 510(k) pathway requires manufacturers to show that their device has the same intended use and similar technological characteristics as one or more predicate devices already cleared for commercial distribution.
Finding the right predicate is a critical step in 510(k) strategy. Manufacturers typically search for cleared devices with the same FDA product code, which groups devices by their intended use and regulatory classification. This tool helps you identify potential predicates by browsing all clearances within a product code.
Note that predicate devices must be legally marketed — they cannot be devices that were cleared but never commercialized, or devices subject to a mandatory recall. The determination of substantial equivalence considers intended use, technological characteristics, and performance data.
