Affinity CP

Centrifugal Blood Pump


The Affinity™ CP pump is now available with two biocompatible surface options.

Offering Choices in Centrifugal Pumps

The Affinity CP centrifugal blood pump, part number AP40, is a low prime centrifugal pump with smooth cone and low-profile fins that gently handles blood, resulting in low hemolysis. It is designed for use with Bio-Console pump speed controllers with a new, high-efficiency remote drive, 560A, providing the durability you've come to expect from Medtronic.

Available with a choice of biocompatible surface options; Cortiva BioActive Surface with non-leaching End Point Attached Heparin, or Balance Biosurface, a hydrophilic biosurface without heparin.

The Affinity CP centrifugal blood pump may be used with the Stöckert and Sorin centrifugal pump systems or the Sarns and Terumo centrifugal systems by attaching the Affinity CP adapter. The adapter may not be available in your country. For more information, contact your local sales representative.

The Affinity CP pump design offers:

  • Low prime with 40 mL priming volume
  • Low-profile fins for efficient blood flow of up to 10 L/min at lower RPMs
  • Low heat generation created by fewer moving parts and ceramic pivot bearings
  • Low impact with even blood flow, low shear, and no stagnant blood zones
  • Low hemolysis with < 0.1 grams hemoglobin released per 100 L blood pumped at 5 L/min

Two Biocompatible Surface Options

Cortiva BioActive Surface

  • Durable, non-leaching End Point Attached Heparin
  • Provides thromboresistance and enhanced blood compatibility

Balance Biosurface*

  • A hydrophilic biosurface option without heparin
  • Reduces platelet activation
  • Reduces platelet adhesion
  • Preserves platelet function1

This addition to the Affinity family is part of the Medtronic commitment to providing more options for patients undergoing cardiopulmonary bypass.
