Intra-aortic balloon

An externally and intermittently inflatable balloon placed into the descending aorta and which, on activation during diastole, augments blood pressure and organ perfusion by its pulsatile thrust; then, on deflation, decreases the cardiac work with each systole-the so-called counterpulsation principle-by reducing cardiac afterload.
