摘要： Apparatus and methods are described including a left-ventricular assist device (20) that includes a pump-outlet tube (28). A mixed-flow impeller (100) is configured to pump blood from a subjects left ventricle to the subjects aorta, by pumping the blood into the pump-outlet tube (28) via one or more blood inlet openings (108) disposed within the left ventricle, and by pumping blood out of the pump-outlet tube (28) via one or more blood outlet openings (30) disposed within the aorta. The mixed-flow impeller (100) includes an expandable portion (116) disposed along its axis and shaped such that a diameter of the expandable portion increases from a distal end of the expandable portion to its proximal end. The mixed-flow impeller (100) is configured to impart radial flow components to blood as the blood flows from its distal end to its proximal end. Other applications are also described.
