K924315 is an FDA 510(k) clearance for the THE MASSAGER. Classified as Massager, Therapeutic, Manual (product code LYG), Class I - General Controls.

Submitted by Four Directions (Seattle, US). The FDA issued a Cleared decision on October 8, 1993 after a review of 408 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Physical Medicine FDA review panel, regulated under 21 CFR 890.5660 - 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.
