Abstract
Official abstract text for this publication.
A blood pump apparatus includes a housing having a blood inlet port and blood outlet port, a pump unit including an impeller that rotates within the housing, and an impeller rotational torque generation section. The housing includes a plurality of magnetic members embedded between the impeller and the impeller rotational torque generation section for transmitting a magnetically attractive force generated by the impeller rotational torque generation section to an impeller body. The pump device includes a non-contact bearing mechanism for rotating the impeller without contacting with the inner surface of the housing when the impeller is rotated by the impeller rotational torque generation section.
First claim
Opening claim text (preview).
What is claimed is: 1. A blood pump apparatus, comprising: an impeller rotatably positioned in a blood chamber to transfer blood from a blood inlet port through the blood chamber and to a blood outlet port, wherein a plurality of first magnetic members are embedded in the impeller so that the impeller and the plurality of first magnetic material members rotate together within the blood chamber; a motor that is positioned adjacent the blood chamber and that is separated from the…
