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.
Device, Biofeedback
Neurology
The Biofeedback Device is a neurological therapeutic instrument that measures physiological parameters such as muscle tension, skin conductance, heart rate, or brain wave activity and provides real-time feedback to patients to help them learn voluntary control over these functions for stress reduction, pain management, or rehabilitation. It is classified as a Class 2 device (moderate risk). The product code is HCC under regulation 21 CFR 882.5050 in the Neurology specialty. No implant, life-sustaining, GMP exempt, or third-party review flags apply.

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.
