ABSTRACT:
An extracorporate ventricular support system includes a two bladder pump employing continuous gravity fill to the first bladder, while the second bladder is pneumatically driven to produce a pulsatile blood flow. A processor responds to air flow in the pneumatic drive line to control the pump through an electromagnetic valve supplying pressurized air. The program controls the output of blood volume per stroke to meet a target value.
