The Medtronic 560A Affinity CP is a brushless DC centrifugal pump motor designed for cardiopulmonary bypass (CPB) and ECMO applications. It delivers precise flow up to 9.99 L/min with minimal hemolysis, using magnetic coupling and battery backup for uninterrupted operation. Compact, non-arcing, and compatible with Bio-Console 560, it ensures reliable cardiac surgery performance while integrating seamlessly into modern OR setups.

What Are Key Specifications of the 560A Motor?

The 560A features RPM ranges from 0 to 4500 and supports flows up to 9.99 L/min. It operates on 100–240V AC with internal rechargeable 12VDC batteries lasting 18–24 hours. LED displays provide real-time RPM, flow, and pressure monitoring (-300 to +999 mmHg). Its compact pole-mount design integrates arterial auto-clamps and level sensors to prevent backflow, while storage ranges from -40 to +66°C.

Biocompatible options such as Cortiva™ BioActive Surface reduce trauma, making it suitable for prolonged ECMO support.

How Does the 560A Compare to Roller Pumps?

The 560A offers superior flow (up to 9.99 L/min vs 5–7 L/min) and lower hemolysis compared to standard roller pumps. Its centrifugal design gently accelerates blood through magnetic coupling, minimizing shear stress. Remote drive capability and optional HC150A handcrank provide flexibility and backup during emergencies. Clinical results show up to 50% reduction in trauma versus roller pumps, making it ideal for high-stakes perfusion.

ALLWILL recommends the 560A for critical cardiac procedures, offering refurbished units via Lasermatch for cost-effective deployment.

What Are Its Clinical Applications?

The 560A is used in cardiopulmonary bypass for heart surgeries, ECMO for respiratory support, and perfusion circuits, supporting adult and pediatric patients. Auto-clamp and level sensors prevent air emboli, and compatibility with Affinity Pixie allows safe neonatal use. Its non-arcing operation ensures safety in oxygen-rich OR environments. ALLWILL’s MET system connects practitioners with certified technicians for efficient integration.

Why Choose a Low Hemolysis Design?

Low hemolysis reduces blood trauma by minimizing shear stress through smooth cone geometry and low-profile fins. Biocompatible coatings like Cortiva™ or Balance™ prevent clotting without heparin leaching, and ceramic bearings reduce heat generation, maintaining plasma-free hemoglobin below 0.1 g/dL. This design supports extended ECMO runs critical for ARDS recovery, with up to 50% less cellular damage than older pumps.

How to Maintain the 560A Motor?

Routine maintenance includes battery recharge, RPM calibration via Bio-Console, and sterile cleaning per instructions. ALLWILL’s Smart Center conducts inspections, calibrations, and refurbishments to maintain peak performance. Daily checks involve LED display verification, handcrank testing, and cabling inspection. Annual flow transducer calibration is recommended. Trade-up programs provide seamless upgrades to newer models without additional recertification costs.

Can the 560A Integrate with Modern Systems?

Yes, it interfaces via RS-232 with consoles, flow transducers, and sensors, supporting digital outputs for RPM, flow, and alarms at 1200–19200 baud. Pole-mount versatility suits most OR setups. Paired with Bio-Console 560, it enables arterial auto-clamp operation and cardiac index calculations. ALLWILL’s brand-agnostic consultations ensure smooth integration in hybrid OR suites.
