Abstract: | A new kind of total implantable artificial heart (TIAH), developed by the author, offers miniaturization with good hemodynamic and physiologic properties. The heart has two units of function, and each has two blood sacs, compressed and expanded by twos, that are filled from one circulation and push out the blood in the other circulation, one after the other. Therefore, the blood flow is continuous and modulated, regulated by pneumatic controlled membrane valves. Shaped plates mechanically synchronized by a pushing rod control compression and expansion of the blood sacs. Starling, atrium, Windkessel, and Anrep effects are guaranteed by construction. The heart can be used for bridging toward transplantation, for definitive substitution of the heart, and for a new kind of therapy--"extracorporeal regeneration of organs." |
