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.
Protective Coating, Mucoadhesive Application, For The Rectal Mucosa
Unknown
The Protective Coating for the Rectal Mucosa is a mucoadhesive device intended for the protective coating of the rectal mucosal surface. It is classified as "Unclassified" (Class U) by the FDA, meaning it has been cleared via 510(k) but has not been formally assigned to a specific device class. The product code is PHN, reviewed by the Gastroenterology and Urology (GU) panel, with no regulation number or medical specialty formally assigned. This device is not an implant and is not life-sustaining.

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.
