More Information
Summary:An apparatus comprising: a ventricular assist device (20) comprising: an axial shaft (92); an impeller (50) disposed on the axial shaft (92), the impeller (50) being configured to pump blood; a frame (34) disposed around the impeller (50); a distal thrust bearing (260), the distal end of the axial shaft (92) being configured to engage with the distal thrust bearing (260) such as to prevent the axial shaft (92) from undergoing axial motion in response to variations in the pressure gradient against which the impeller (50) pumps blood; and an impeller-stabilizing spring (68) disposed around the axial shaft (92) between a distal end of the impeller (50) and the thrust bearing (260), the impeller-stabilizing spring (68) being configured to stabilize the distal end of the impeller (50).
