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; Carmeda^® BioActive Surface with non-leaching End Point Attached Heparin or Balance^® Biosurface, a hydrophilic biosurface without heparin.

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

Carmeda^® 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 Medtronic's commitment to providing more options for patients undergoing cardiopulmonary bypass.
