K936091 is an FDA 510(k) clearance for the MEDTRONIC BIO-MEDICUS BIO-CONSOLE MODEL 550M PUMP SPEED CONTROLLER. Classified as Control, Pump Speed, Cardiopulmonary Bypass (product code DWA), Class II - Special Controls.

Submitted by Medtronic Bio-Medicus, Inc. (Eden Prairie, US). The FDA issued a Cleared decision on December 23, 1994 after a review of 366 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Cardiovascular FDA review panel, regulated under 21 CFR 870.4380 - 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.

Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 870.4380
What this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. This pathway does not require clinical trials - it relies on engineering equivalence and performance data. Most Cardiovascular devices follow this clearance model.
