K941922 is an FDA 510(k) clearance for the MEDSAT OXYGEN SATURATION SYSTEM. Classified as Monitor, Blood-gas, On-line, Cardiopulmonary Bypass (product code DRY), Class II - Special Controls.

Submitted by Medtronic Bio-Medicus, Inc. (Eden Prairie, US). The FDA issued a Cleared decision on February 17, 1995 after a review of 303 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Cardiovascular FDA review panel, regulated under 21 CFR 870.4330 - 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: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Cardiovascular review framework, consistent with the majority of Class II 510(k) submissions.
