A sealed gold, titanium, or platinum isotope source is a brachytherapy source in which a radioactive material is permanently sealed within a metal capsule, used for interstitial or intracavitary radiation therapy to deliver localized doses to target tissue. It is classified as FDA Class 2, indicating moderate risk and requiring 510(k) premarket notification. The product code is IWI, regulated under 21 CFR 892.5730, within the Radiology medical specialty. This device 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.
