Abstract
A prosthetic myocardium is disclosed for replacing necrotic or scarred myocardial tissue to positively simulate both myocardial contraction and expansion during systole and diastole. The prosthetic device includes several circumferentially arranged tilting arms which are sutured to the periphery of an opening in the heart formed by a medical excision. The tilting arms are pivotally supported and functionally interconnected with an axially reciprocal drive rod which effects synchronized inward and outward pivoting of the tilting arms to simulate the myocardial functions during heartbeat.
