ABSTRACT:
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.
