K191938 is an FDA 510(k) clearance for the FitRelief TENS&EMS Wireless Device. Classified as Stimulator, Muscle, Powered, For Muscle Conditioning (product code NGX), Class II - Special Controls.
Submitted by Heat IN A Click, LLC (Dania, US). The FDA issued a Cleared decision on August 28, 2020 after a review of 406 days - an unusually long review period, suggesting complex equivalence evaluation.
This device falls under the Neurology FDA review panel, regulated under 21 CFR 890.5850 - 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.
