K220035 is an FDA 510(k) clearance for the Milli Vaginal Dilator. Classified as Dilator, Vaginal (product code HDX), Class II - Special Controls.

Submitted by Materna Medical (Mountain View, US). The FDA issued a Cleared decision on February 27, 2023 after a review of 418 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Obstetrics & Gynecology FDA review panel, regulated under 21 CFR 884.3900 - 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.
