Product Code: KOI FDA class 2

Stimulator, Nerve, Peripheral, Electric

Anesthesiology

View full classification →

An Electric Peripheral Nerve Stimulator is a device used in anesthesiology to deliver controlled electrical pulses to peripheral nerves, assessing neuromuscular blockade levels during and after general anesthesia to guide the use of muscle relaxants and confirm adequate neuromuscular recovery before extubation. It is classified as FDA Class 2, indicating moderate risk requiring 510(k) premarket notification. The product code is KOI and it is regulated under 21 CFR 868.2775 in the Anesthesiology specialty. This device is eligible for third-party review.

What is a Predicate Device?

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.
