Cup, Menstrual
Obstetrics/Gynecology
The Menstrual Cup is an intravaginal device made of flexible material, designed to be inserted into the vaginal canal to collect rather than absorb menstrual fluid, and can be emptied, cleaned, and reused. It is classified as FDA Class 2 (moderate risk) within the Obstetrics/Gynecology specialty and is subject to premarket controls. The product code is HHE, regulated under 21 CFR 884.5400. No special risk flags apply.

A predicate device is a legally marketed device that a new 510(k) applicant uses to demonstrate substantial equivalence. The FDA's 510(k) pathway requires manufacturers to show that their device has the same intended use and similar technological characteristics as one or more predicate devices already cleared for commercial distribution.
Finding the right predicate is a critical step in 510(k) strategy. Manufacturers typically search for cleared devices with the same FDA product code, which groups devices by their intended use and regulatory classification. This tool helps you identify potential predicates by browsing all clearances within a product code.
Note that predicate devices must be legally marketed — they cannot be devices that were cleared but never commercialized, or devices subject to a mandatory recall. The determination of substantial equivalence considers intended use, technological characteristics, and performance data.
