    Abstract: Apparatus and methods are described including a tube configured to traverse a subject's aortic valve. A frame is disposed within a portion of the tube, and an impeller is disposed inside the tube such that, when the impeller and the tube are deployed inside the subject, a gap between an outer edge of the impeller and an inner surface of the tube is less than 1 mm. The impeller rotates such as to pump blood from the left ventricle to the aorta, and is stabilized with respect to the tube, such that, during rotation of the impeller, the gap between the outer edge of the impeller and the inner surface of the tube is maintained. The impeller includes at least one impeller blade defined by a helical elongate element, and a film of material supported by the helical elongate element. Other applications are also described.

    Abstract: Apparatus and methods are described for manufacturing a housing for an impeller of a blood pump. A frame is treated in order to enhance bonding between an inner surface of the frame and an inner lining. Subsequently, the inner lining is coupled to the inner surface of the frame along at least a portion of a central cylindrical portion of the frame. Subsequent to coupling the inner lining to the inner surface of the frame along at least a portion of the central cylindrical portion of the frame, a portion of an elongate tube is placed around at least a portion of the frame. While heating the inner lining, the frame, and the portion of the elongate tube, pressure is applied such as to cause the portion of the elongate tube to become coupled to the frame. Other applications are also described.

    Abstract: Apparatus and methods are described including a left-ventricular assist device including an impeller and a frame disposed around the impeller. A pump-outlet tube traverses the subject's aortic valve with a distal portion of the pump-outlet tube disposed within the subject's left ventricle. The distal portion of the pump-outlet tube extends to a distal end of the frame and defines more than 10 blood-inlet openings that are sized such as (a) to allow blood to flow from the subject's left ventricle into the tube and (b) to block structures from the subject's left ventricle from entering into the frame. The porosity of the distal portion of the pump-outlet tube is lower within a proximal region of the distal portion of the pump-outlet tube than within a distal region of the distal portion of the pump-outlet tube that is distal to the proximal region. Other applications are also described.
