K910599 is an FDA 510(k) clearance for the CARDIOPULMONARY BYPASS LEVEL SENSING MONITOR. Classified as Monitor And/or Control, Level Sensing, Cardiopulmonary Bypass (product code DTW), Class II - Special Controls.

Submitted by Jtl Medical Corp. (Riverside, US). The FDA issued a Cleared decision on May 20, 1993 after a review of 827 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Cardiovascular FDA review panel, regulated under 21 CFR 870.4340 - 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.
