K771991 is an FDA 510(k) clearance for the CARDIAC OUTPUT THERMODILUTION MODULE. Classified as Computer, Diagnostic, Pre-programmed, Single-function (product code DXG), Class II - Special Controls.

Submitted by Abbott Laboratories (Abbott Park, US). The FDA issued a Cleared decision on November 3, 1977 after a review of 15 days - a notably fast clearance cycle.

This device falls under the Cardiovascular FDA review panel, regulated under 21 CFR 870.1435 - 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: Fast-track predicate clearance. Standard predicate reliance. The short review cycle indicates strong predicate alignment - the FDA found sufficient equivalence without extended technical review.
