K920388 is an FDA 510(k) clearance for the RS-1 NEUROMUSCULAR STIMULATOR. Classified as Stimulator, Muscle, Powered (product code IPF), Class II - Special Controls.

Submitted by Rs Medical (Washington, US). The FDA issued a Cleared decision on January 28, 1993 after a review of 364 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: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Physical Medicine review framework, consistent with the majority of Class II 510(k) submissions.
