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, Sensing, Optical Contour
Unknown
An optical contour sensing device is a system that uses optical measurement techniques to detect or map the surface contour or shape of a body part or object, potentially for use in prosthetics fitting, orthopedic assessment, or physical medicine applications. This device is currently unclassified by the FDA, with no assigned regulation number or medical specialty, meaning its regulatory classification has not been finalized. The product code is LDK. No special risk 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.
