K910624 is an FDA 510(k) clearance for the CASE IV COMPUTER AIDED SENSORY EVALUATOR VERSION 4. Classified as Device, Vibration Threshold Measurement (product code LLN), Class I - General Controls.

Submitted by Wr Medical Electronics Co. (Stillwater, US). The FDA issued a Cleared decision on January 17, 1992 after a review of 339 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Neurology FDA review panel, regulated under 21 CFR 882.1200 - 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: Incremental AI imaging tool. Moderate-to-high equivalence dependency. Overall, this clearance reflects a predicate-aligned approval typical of modern AI radiology extensions - not a novel clinical breakthrough, but a validated iteration within an established regulatory category.
