ABSTRACT:
An artificial heart comprising a case with inlet and outlet openings for blood which can be implanted in human body instead of an incurable human heart and can provide the normal blood flows in both large (body) and small (lungs) blood circulations for a long period (years). It has a driving arrangement which has a driver armed with magnets and is placed outside the human body. The case is formed with cylindrical wall and two end plates and contains a movable grid consisting of twelve elongated wall elements which are disposed between said plates and which bear slidingly and sealingly on said plates, each wall element being articulately sealingly connected at its end points to at least one further wall element. The grid has nine axles; the central one is connected at least with one of the said plates, the remaining axles are free. The grid is armed with permanent magnets which cause the grid's rotation by their magnet coupling with the driving magnets of the driver. The grid has four cells and together with the end plates forms four operating chambers which alternate their volumes during rotation of grid and work as pump chambers for blood.
