ABSTRACT:
A blood pump includes a housing having an inlet and outlet communicating with a pump chamber. A rotor received in the pump chamber is rotated by a drive motor. A drive shaft extending between the motor and rotor is sealed by a fluid seal. The housing includes an opening defining a clearance with the drive shaft on the order of one or two thousandth (0.002) of an inch. A viscous, biocompatible fluid is utilized as the seal fluid.
