K112695 is an FDA 510(k) clearance for the CRYOTOP. Classified as Labware, Assisted Reproduction (product code MQK), Class II - Special Controls.

Submitted by Kitazato Biopharma Co;Ltd (Austin, US). The FDA issued a Cleared decision on December 12, 2012 after a review of 454 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Obstetrics & Gynecology FDA review panel, regulated under 21 CFR 884.6160 - the FDA obstetrics and gynecology 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 Obstetrics & Gynecology submissions.
