A fluid pressure generating means () for a heart assist device having blood pumping means. The pressure generating means () includes a housing (), defining an interior volume (), and having a substantially rigid first housing portion (), a substantially rigid second housing portion (), a flexible third housing portion () extending between the first () and second () housing portions and an inlet/outlet port () adapted for fluid communication with the blood pumping means. The pressure generating means () also includes a fluid filling the housing and a motor () disposed within the housing () and connected between the first () and second () housing portions. Actuation of the motor () moves the first () and second () housing portions relative to one another to generate fluid pressure changes at the inlet/outlet port (). A related heart assist device and method for the treatment of congestive heart failure, myocardial ischemia and like conditions are also disclosed.
