K172450 is an FDA 510(k) clearance for the TENS device-HeadaTerm, eEspress. Classified as Stimulator, Nerve, Electrical, Transcutaneous, For Migraine (product code PCC), Class II - Special Controls.

Submitted by Wat Medical Technology (Ningbo) Co., Ltd. (Ningbo, CN). The FDA issued a Cleared decision on September 13, 2018 after a review of 395 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Neurology FDA review panel, regulated under 21 CFR 882.5891 - 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: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Neurology review framework, consistent with the majority of Class II 510(k) submissions.
