Magnetisch gelagerter und angetriebener Kreiselpumpenapparat.
摘要
A novel pump apparatus and method, the pump (10) including a magnetically suspended and rotated impellor (20) inside the pump housing (12). A novel sensor system (34, 35) detects the position of the impellor (20) and thus provides the necessary information for operation of a suspension circuit for magnetically suspending the impellor (20). A valve member (22) may be included as part of the impellor (20) to prevent reverse flow in the event of impellor failure when used as a ventricular assist device.
