Beschreibung
Zusammenfassung:	Apparatus comprising: a blood pump (20) comprising: an axial shaft (92); a frame (34); an impeller (50) disposed on the axial shaft inside the frame (34); a motor (74) configured to be disposed outside a body of the subject, and configured to drive the impeller (50) to pump blood from a distal end of the impeller (50) to a proximal end of the impeller (50), by rotating the impeller (50) in a given direction of rotation; a drive cable (130) configured to extend from outside the subject's body to the axial shaft (92), the drive cable (130) being configured to impart rotational motion from the motor (74) to the impeller (50) by rotating, wherein the drive cable (130) is held in a preloaded state with respect to the frame (34), such that initiation of pumping of blood by rotation of the impeller (50) does not cause the drive cable (34) to axially elongate.
