| Research Abstract |
We have studied a compliance chamber built in a inflow cannula of a pulsatile blood pump for reduction of space occupied by the compliance chamber. We also have developed magnetically suspended non-contact cam system to convert from rotational motion of a motor into rectilinear motion of pusher-plate to drive a total artificial heart. We confirmed performance of them in in-vitro experiments. While further studies are required to use our studies clinically, our study contributes to overcome drawback of a pulsatile artificial heart, and to develop a new small pulsatile artificial heart having life over 5 years like a non-pulsatile artificial heart.
