An auxiliary artificial heart embedded in the human body. The auxiliary artificial heart has an apex cordis area ring and a body. The apex cordis area ring is embedded in a cut-out apex cordis area of the human heart. The body includes an elongated pump section and a drive section. The pump section is inserted into one of the ventricles of the human heart, passing through the apex cordis area ring. A front end nozzle whose diameter is smaller than that of the pump section is formed at the front end of the pump section, and it is inserted into the aorta or pulmonary artery, passing through the center of the aorta or pulmonary valve. The pump section sucks blood in the ventricle through its base portion and feeds it into the aorta or pulmonary artery through the front end nozzle.

L'invention porte sur un coeur artificiel auxiliaire, implanté dans le corps humain, qui comporte une bague dans la zone de la pointe du coeur et un corps. La bague de la zone de la pointe du coeur est implantée dans une zone entaillée de la pointe du coeur d'une personne. Le corps comprend une section de pompage allongée et une section d'entraînement. La section de pompage est insérée dans un des ventricules du coeur humain et passe à travers la bague de la zone de la pointe du coeur. Une buse, dont le diamètre est inférieur à celui de la section de pompage, est formée sur l'extrémité avant de la section de pompage et est insérée dans l'aorte ou dans l'artère pulmonaire en passant par le centre de l'aorte ou de la valvule pulmonaire. La section de pompage aspire le sang dans le ventricule par le biais de sa base et en alimente l'aorte ou l'artère pulmonaire par la buse sur l'extrémité avant.
