K970367 is an FDA 510(k) clearance for the THERMO-STAT SYSTEM. Classified as System, Thermal Regulating (product code DWJ), Class II - Special Controls.

Submitted by Aquarius Medical Corp. (Scottsdale, US). The FDA issued a Cleared decision on December 17, 1997 after a review of 320 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Cardiovascular FDA review panel, regulated under 21 CFR 870.5900 - 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.
