ABSTRACT:
A novel pump apparatus and method, the pump including a magnetically suspended and rotated impellor inside the pump housing. A novel sensor system detects the position of the impellor and thus provides the necessary information for operation of a suspension circuit for magnetically suspending the impellor. A valve member may be included as part of the impellor to prevent reverse flow in the event of impellor failure when used as a ventricular assist device.
