K120577 is an FDA 510(k) clearance for the MEDIKRO SPIROSTAR, M929 Medikro Spirostar USB and M921 Medikro SpiroStar DX. Classified as Spirometer, Diagnostic (product code BZG), Class II - Special Controls.

Submitted by Medikro OY (Kuopio, FI). The FDA issued a Cleared decision on June 24, 2015 after a review of 1213 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Anesthesiology FDA review panel, regulated under 21 CFR 868.1840 - the FDA anesthesiology and respiratory 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 Anesthesiology submissions.
