Abstract
Temporary circulatory assist devices now appear to hold more promise of clinical application than permanent, implanted artificial hearts. Two contrasting approaches to temporary assist are described: the bypass and the counterpulsation pump. The latter has developed into a completely external system through which coronary filling is enhanced and blood delivered to the systemic circulation during diastole.
