More Information
Summary:Apparatus and methods are described including a ventricular assist device. An impeller is placed inside a left ventricle of a subject, the impeller defining a lumen therethrough. A frame is disposed around the impeller, with a proximal bearing disposed at a proximal end of the frame and a distal bearing disposed at a distal end of the frame. An axial shaft passes through the proximal bearing, the lumen defined by the impeller, and the distal bearing. A motion-cushioning spring is disposed around the axial shaft between a distal end of the impeller and the distal bearing, the motion-cushioning spring being configured to cushion axial motion that the impeller undergoes. Other applications are also described.
