K221606 is an FDA 510(k) clearance for the Absorbable Cranial Flap Fixation System. Classified as Cover, Burr Hole (product code GXR), Class II - Special Controls.

Submitted by Chendu Medart Medical Scientific Co., Ltd. (Chengdu, CN). The FDA issued a Cleared decision on November 21, 2023 after a review of 537 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Neurology FDA review panel, regulated under 21 CFR 882.5250 - 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: 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 Neurology submissions.
