K930088 is an FDA 510(k) clearance for the FORTRESS C-500 MICROPROCESSOR CONTROLLER. Classified as Wheelchair, Powered (product code ITI), Class II - Special Controls.

Submitted by Fortress Scientific , Ltd. (Washington, US). The FDA issued a Cleared decision on March 28, 1994 after a review of 445 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Physical Medicine FDA review panel, regulated under 21 CFR 890.3860 - 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.
