The Cryogenic Surgical Device is a neurosurgical instrument that uses extreme cold to destroy or ablate targeted brain tissue, used in procedures such as cryosurgery for tumors or functional neurosurgery for movement disorders. It is classified as a Class 2 device (moderate risk), requiring 510(k) premarket notification to confirm substantial equivalence to a predicate device. The product code is GXH under regulation 21 CFR 882.4250 in the Neurology specialty. It is eligible for third-party 510(k) review.

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.
