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.
Circulating Tumor Cell (Ctc) Enrichment Device
Immunology
The Circulating Tumor Cell (CTC) Enrichment Device is an in vitro diagnostic device used to enrich circulating tumor cells from the peripheral blood of cancer patients, enabling subsequent downstream diagnostic testing and analysis of tumor cell characteristics. It serves as a preparatory step in liquid biopsy workflows. Classified as FDA Class 2 under regulation 866.6110, it requires 510(k) clearance and falls under the Immunology specialty. The device is not an implant and 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.
