Submitted by Advanced Medical Systems, Inc. (Hamden, US). The FDA issued a Cleared decision on March 1, 1995 after a review of 370 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Obstetrics & Gynecology FDA review panel, regulated under 21 CFR 884.2740 - 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: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Obstetrics & Gynecology review framework, consistent with the majority of Class II 510(k) submissions.
