K200558 is an FDA 510(k) clearance for the Smart Neck Stimulator. Classified as Stimulator, Nerve, Transcutaneous, Over-the-counter (product code NUH), Class II - Special Controls.
Submitted by Guandong Skg Intelligent Technology Co., Ltd. (Shunde District, Foshan City, CN). The FDA issued a Cleared decision on October 4, 2021 after a review of 580 days - an unusually long review period, suggesting complex equivalence evaluation.
This device falls under the Neurology FDA review panel, regulated under 21 CFR 882.5890 - the FDA neurology device framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.
Device pattern: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind Neurology submissions.
