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.
System, Processing For Frozen Blood
Hematology
This device is a processing system for frozen blood, used to thaw, wash, and reconstitute cryopreserved red blood cells to remove the cryoprotective agent (typically glycerol) prior to transfusion, restoring the cells to a transfusable state. It is classified as FDA Class 2, indicating moderate risk, and requires 510(k) premarket notification. The product code is KSW, regulated under 21 CFR 864.9145 within the Hematology specialty. No special 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.
