Abstract
Artificial implantable active and passive girdles include a heart assist system with an artificial myocardium employing a number of flexible, non-distensible tubes with the walls along their long axes connected in series to form a cuff and a passive girdle is wrapped around a heart muscle which has dilatation of a ventricle to conform to the size and shape of the heart and to constrain the dilatation during diastole. The passive girdle is formed of a material and structure that does not expand away from the heart but may, over an extended period of time be decreased in size as dilatation decreases.
