K931814 is an FDA 510(k) clearance for the DMI UTERINE MOBILIZER/ELEVATOR/CANNULA. Classified as Cannula, Manipulator/injector, Uterine (product code LKF), Class II - Special Controls.

Submitted by Diversified Medical Instruments, Inc. (Ellicott City, US). The FDA issued a Cleared decision on May 31, 1994 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 884.4530 - 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.
