K121664 is an FDA 510(k) clearance for the T4/T5 HYTREL TOGAS. Classified as Gown, Surgical (product code FYA), Class II - Special Controls.

Submitted by Stryker Corporation (Kalamazoo, US). The FDA issued a Cleared decision on March 10, 2014 after a review of 643 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the General Hospital FDA review panel, regulated under 21 CFR 878.4040 - the FDA general hospital 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 General Hospital submissions.
