1 Description
The Affinity CP centrifugal blood pump with Cortiva bioactive surface (CBAP40) is intended for use in extracorporeal circulation
procedures. It is designed to move blood by centrifugal force generated by a combination of a smooth rotating cone and low-profile
impeller fins. Energy is transferred from the pump in the form of pressure and velocity as the blood is driven toward the outlet port of
the pump. To limit friction and heat generation, the Affinity CP centrifugal blood pump with Cortiva bioactive surface utilizes a
pivot-bearing design on a dual ceramic pivot.
The Affinity CP centrifugal blood pump with Cortiva bioactive surface has been sterilized using ethylene oxide.
Products coated with Cortiva bioactive surface include a "CB" prefix in the model number. Additional information regarding Cortiva
bioactive surface is available in Chapter 7.
The Affinity CP centrifugal blood pump with Cortiva bioactive surface couples to a remote magnetic drive unit called the external drive
motor model 560A, which interfaces with a Medtronic pump speed controller. It also couples with the emergency handcrank
model HC150A in the event of controller or power failure. Refer to the appropriate Medtronic pump speed controller operator's manual
for additional information about the external drive motor and the emergency handcrank.
The Affinity CP centrifugal blood pump with Cortiva bioactive surface also couples with the Affinity CP adapter to enable the pump to
be operated with the Stöckert™ and Sorin™ centrifugal pump systems or the Sarns™ and Terumo™ centrifugal systems.
The adapter may not be available in your country. Contact your Medtronic representative to confirm if the adapter is available.
For additional information on using the Affinity CP adapter or operating the Medtronic pump speed controller or accessories, refer to
the instructions for use or operator's manual.

2 Indications for use
The Affinity CP centrifugal blood pump with Cortiva bioactive surface is used to pump blood through the extracorporeal bypass circuit
for extracorporeal circulatory support for periods appropriate to cardiopulmonary bypass (up to 6 hours).
It is also indicated for use in extracorporeal support systems (for periods up to 6 hours) not requiring complete cardiopulmonary bypass
(for example, valvuloplasty, circulatory support during mitral valve reoperation, surgery of the vena cava or aorta, liver transplants).
The Affinity CP centrifugal blood pump with Cortiva bioactive surface is driven by the external drive motor or the emergency handcrank.
The Affinity CP centrifugal blood pump with Cortiva bioactive surface is intended for use with Medtronic controllers or may be used with
the Stöckert and Sorin centrifugal pump systems or the Sarns and Terumo centrifugal systems by attaching the Affinity CP adapter.
3 Contraindications
The Affinity CP centrifugal blood pump with Cortiva bioactive surface is contraindicated for use as a cardiotomy suction device. Use
the device only as indicated.
4 Warnings
Read all warnings, precautions, and instructions for use carefully prior to use. Failure to read and follow all instructions, or failure to
observe all stated warnings, could cause serious injury or death to the patient.
