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.
Let the assistant find your predicates
Describe your device and the Research Assistant searches 510(k)s, compares intended use, and drafts a predicate shortlist — with citations.

X-Ray Field Indicator Light (Laser)
Radiology
The X-Ray Field Indicator Light (Laser) is a laser incorporated into a diagnostic x-ray system that projects onto the field being imaged to assist in aligning the x-ray beam with the intended target area. It falls under the medical specialty of Radiology with product code RGC and regulation number 892.5780. This device is Class 1, meaning it is subject to general controls, which are the least stringent regulatory requirements, reflecting the device's low risk profile. It is not flagged as an implant or life-sustaining device, and no premarket submission is required. This laser accessory aids in the safe and accurate positioning of diagnostic x-ray equipment.

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.
