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.

Port & Catheter, Implanted, Subcutaneous, Intraventricular
Neurology
Port and Catheter, Implanted, Subcutaneous, Intraventricular is a totally implantable access system consisting of a subcutaneous reservoir (port) connected to a catheter that accesses a cerebral ventricle, used for long-term drug delivery directly into the cerebrospinal fluid or for drainage of cerebrospinal fluid. This is an FDA Class 2 device, indicating moderate risk, and requires 510(k) premarket clearance. The product code is LKG, regulated under 21 CFR 882.5550, within the Neurology medical specialty. This device is an implant.

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.
