K040335 is an FDA 510(k) clearance for the MOONCUP, STYLE A & B. Classified as Cup, Menstrual (product code HHE), Class II - Special Controls.

Submitted by Mooncup, LLC (Madison, US). The FDA issued a Cleared decision on March 30, 2005 after a review of 413 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Obstetrics & Gynecology FDA review panel, regulated under 21 CFR 884.5400 - 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.
