The Thoratec CentriMag Blood Pump is indicated for use only with the Thoratec Console to pump WARNING (Definition) blood through the extracorporeal bypass circuit for extracorporeal circulatory support for periods Warnings are used if there is a potential for appropriate to cardiopulmonary bypass (up to six a serious hazard with misuse of the device, hours). It is also indicated for use in when special attention is required for extracorporeal support systems (for periods up to safety of the patient, or when special care six hours) not requiring complete should be exercised to prevent improper cardiopulmonary bypass (e.g. valvuloplasty, operation of the device that may cause circulatory support during mitral valve damage. reoperation, surgery of the vena cava or aorta, liver transplants etc.) This device is not designed, sold, or intended for use except as indicated.

These are potential side effects with all extracorporeal blood systems. 4. Ensure that the Pump and circuit have been debubbled and primed properly prior to beginning bypass to minimize the risk of air reaching the patient. The use of an arterial filter is recommended. 5. Massive air entry into the Pump will cause the Pump to deprime and blood flow to stop. Stop the Pump and remove air prior to resuming circulation. Figure 1 – CentriMag Blood Pump 6.
