Abstract
A fluid isolator is used to separate a drive gas from a drive air. A pulsation in the air pressure is produced to drive a balloon pump placed within the aorta through the drive gas. The gas pressure on the secondary side is determined as the air pressure applied to the primary side of the isolator is a positive pressure, and the quantity of gas on the secondary side is automatically regulated in accordance with a result of such determination. The gas pressure may be controlled so as to coincide with a target value, or alternatively, the quantity of gas may be controlled in accordance with a difference between the gas pressure and the blood pressure of a physical body.
