Abstract
A blood pump for use in CPB and other heart surgeries includes a reusable motor stator element which is enclosed in a disposable, sterile pump housing. The reusable, non-sterilized motor stator element is completely encased by the pump housing so that the motor stator can be reused without sterilization. The sterile housing allows the blood pump to be placed closed to the patient and within the sterile surgical field. The placement of the blood pump close to the heart during heart surgery greatly reduces the priming volume of the system thereby reducing the amount of saline or drugs which are introduced the patient's blood. The sterile housing may be evacuated to reduce the risk of emboli which may occur due to the failure of a seal.
