Design of an Electric Drive for a Total Artificial Heart based on a Rotary Piston PumpCopyright: © IEM
Total artificial hearts (TAH) provide the potential to adequately support the body with blood in the event of chronic heart insufficiency. Among these, a TAH based on a rotary piston pump represents a special design. Because of the problematic sealing of mechanical components, this design could however not yet establish itself. In Cooperation with the Institute of Applied Medical Engineering (AME CVE) sealless bearing- and drive concepts have been developed, potentially allowing for a permanently safe operation of the system. A magnetic gear replaces a mechanic gear for guidance of the piston, while the necessary torque can be transmitted via magnetic coupling.
