K122393 is an FDA 510(k) clearance for the TG-BODY MI&BODY S-TRAINER. Classified as Stimulator, Muscle, Powered, For Muscle Conditioning (product code NGX), Class II - Special Controls.

Submitted by Miga Medical Co., Ltd. (Gangnam-Gu, KR). The FDA issued a Cleared decision on December 10, 2013 after a review of 490 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Physical Medicine FDA review panel, regulated under 21 CFR 890.5850 - the FDA physical medicine 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 Physical Medicine submissions.
