Description

The Medtronic CBAP40 Affinity CP Centrifugal Blood Pump is a cornerstone of modern perfusion technology, designed to provide high-performance extracorporeal blood flow during cardiac surgery. Engineered for both safety and efficiency, this single-use, sterile component is specifically optimized for clinicians who require low priming volumes without compromising flow capacity.

Featuring the proprietary Cortiva™ BioActive Surface, the CBAP40 addresses the critical challenge of biocompatibility in cardiopulmonary bypass (CPB). By integrating advanced surface chemistry with a precision-engineered cone design, Medtronic delivers a solution that minimizes blood trauma and simplifies the perfusionist’s workflow.


Core Technology: Cortiva™ BioActive Surface

The defining feature of the CBAP40 is its Cortiva BioActive Surface, an industry-leading heparin coating technology. Unlike traditional coatings, Cortiva employs a non-leaching, covalently bonded heparin that mimics the natural vascular endothelium.

  • Thromboresistance: Actively reduces the risk of clot formation on the pump’s internal surfaces.

  • Biocompatibility: Minimizes the systemic inflammatory response by reducing protein adsorption and platelet activation.

  • Sustainability: The non-leaching design ensures that the heparin remains effective throughout the duration of long-term surgical procedures.


Mechanism of Action: Low-Shear Centrifugal Flow

The CBAP40 operates on a centrifugal principle rather than positive displacement (roller pumps). It utilizes magnetic coupling to connect with the Bio-Console drive motor, creating a “shaftless” environment.

As the internal smooth-cone assembly rotates, it creates a pressure differential that draws blood through the 3/8″ inlet and accelerates it outward toward the outlet. This design eliminates the mechanical occlusion found in roller pumps, significantly reducing hemolysis (the destruction of red blood cells) and preventing heat buildup, which is vital for maintaining blood integrity during sustained circulation.


Applications and Clinical Uses

The Affinity CP CBAP40 is a versatile component designed for high-stakes surgical environments:

  • Adult and Pediatric Bypass: Capable of handling flow rates up to 10 L/min, making it suitable for a wide range of patient sizes.

  • Cardiopulmonary Bypass (CPB): The primary driver for blood circulation during open-heart procedures.

  • Short-term Support: Ideal for procedures requiring precise, reliable flow control with minimal blood trauma.


Key Advantages for Perfusion Teams

  • Ultra-Low Priming Volume: At just 40 mL, the CBAP40 helps reduce the need for blood transfusions and minimizes the effects of hemodilution.

  • High Flow Efficiency: Achieves flow rates up to 10 L/min, providing ample support for even the most demanding surgical cases.

  • Seamless Integration: Features universal 3/8″ inlet/outlet ports, ensuring compatibility with the Medtronic Bio-Console or other major systems via standard adapters.

  • Enhanced Safety: Includes an emergency handcrank option, ensuring continued operation in the event of a total power or console failure.

  • Lower Hemolysis: The smooth cone design and magnetic drive reduce mechanical stress on blood components compared to traditional roller pumps.

Frequently Asked Questions

How does the priming volume of the CBAP40 compare to standard roller pumps?

The CBAP40 features a remarkably low priming volume of only 40 mL. In contrast, standard roller pump circuits typically require 150–300 mL. This significant reduction helps minimize hemodilution in the patient, potentially reducing the need for donor blood transfusions and improving overall postoperative outcomes for the patient.

What are the specific benefits of the Cortiva BioActive Surface?

The Cortiva surface uses a non-leaching heparin coating that is covalently bonded to the pump’s interior. This technology enhances biocompatibility by mimicking the body’s own blood vessels. It reduces the risk of thrombosis and inflammatory responses during extracorporeal circulation, providing a safer environment for blood components throughout the procedure.

Can the CBAP40 be used for both adult and pediatric patients?

Yes, the CBAP40 is designed for versatility. Its ability to provide efficient blood flow up to 10 L/min makes it robust enough for adult bypass, while its low 40 mL priming volume makes it an excellent choice for pediatric cases where minimizing circuit volume is critical to patient safety.

What happens if there is a power failure during a procedure?

Safety is a core priority of the Affinity CP system. In the event of a console or power failure, the CBAP40 is compatible with an emergency handcrank option. This allows the perfusionist to maintain manual blood flow and support the patient until the primary system is restored.

How does magnetic coupling reduce hemolysis?

Magnetic coupling allows the pump to operate without a drive shaft passing through the blood chamber. By eliminating the mechanical seals and friction associated with a physical shaft, the pump generates less heat and subjects the blood to lower shear stress, resulting in significantly lower rates of hemolysis.

Is the CBAP40 compatible with non-Medtronic consoles?

While the CBAP40 is optimized for use with the Medtronic Bio-Console, its standard 3/8″ inlet and outlet ports are compatible with a variety of adapters. This allow hospitals to integrate this high-performance pump into most major extracorporeal systems currently used in cardiac surgical suites worldwide.
