1. A blood pump system comprising:
a housing having an inlet and an outlet configured to be in fluid communication with a patient's circulatory system;
a membrane disposed within the housing;
an electromagnetic coil disposed within the housing, the electromagnetic coil configured to cause the membrane to reciprocate to pump blood;
a moving magnetic portion configured to extend around and to move with respect to the electromagnetic coil; and
a top and bottom encapsulator coupled to the moving magnet portion and configured to obstruct blood flow between the electromagnetic coil and the moving magnet portion such that the blood does not contact the electromagnetic coil and the moving magnet portion, the top and bottom encapsulator disposed within the housing and configured to define a blood flow channel between the housing and the top and bottom encapsulator,
wherein, during operation, blood enters the inlet, flow between the housing and the top and bottom encapsulator in the blood flow channel, and is propelled across the membrane to the outlet to pump the blood.
