Apparatus useful in enhancing or assisting the circulation of blood, reducing the work of the heart and increasing the coronary blood flow, said apparatus comprising a rigid, incompressible system which provides an external pulsatile pressure environment on a portion of the body which is synchronous and phased with cardiac action. A rigid chamber or chambers with a liquid filled system of non-distensible, yet expandable, seals houses a portion of the body (e.g., the limbs) in such a way that the pressure exerted on the body can be varied above and below atmospheric pressure by adding or removing liquid from the system.
