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.
Generator, Lesion, Radiofrequency
Neurology
The Radiofrequency Lesion Generator is a neurosurgical device used to create controlled thermal lesions in neural tissue, typically for pain management or the treatment of movement disorders by interrupting aberrant nerve pathways. It is classified as a Class 2 device (moderate risk), requiring 510(k) premarket notification to demonstrate substantial equivalence to a legally marketed predicate device. The product code is GXD under regulation 21 CFR 882.4400 in the Neurology specialty. It is eligible for third-party review under the 510(k) program.

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.
