Abstract
The device comprises a container housing for enveloping, at least partially, the ventricular region of the myocardium. To the inner surface of the container housing are applied membrane means which define pumping chambers between the inner surface and the myocardial wall. A pumping fluid is fed selectively to these chambers to cause expansion of the chambers and consequent compression of the myocardial wall.
