K914273 is an FDA 510(k) clearance for the A&D TM-2421/2021 AMBULATORY BLOOD PRESSURE MONITOR. Classified as Computer, Blood-pressure (product code DSK), Class II - Special Controls.

Submitted by A&D Engineering, Inc. (Milpitas, US). The FDA issued a Cleared decision on February 9, 1993 after a review of 504 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Cardiovascular FDA review panel, regulated under 21 CFR 870.1110 - the FDA cardiovascular device oversight 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 Cardiovascular submissions.
