    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.

    IPC: A61M1/12 ,  A61M1/10

    Abstract: Apparatus and methods are described including manufacturing a housing for an impeller of a blood pump by placing an inner lining around a mandrel, placing a cylindrical portion of a frame around the inner lining, and placing a distal portion of an elongate tube around a portion of the frame. While the distal portion of the elongate tube is disposed around the portion of the frame, the inner lining, the frame, and the distal portion of the elongate tube are heated, via the mandrel, and pressure is applied from outside the distal portion of the elongate tube, such as to cause the distal portion of the elongate tube to conform with a structure of the struts of the frame, and to cause the inner lining and the distal portion of the elongate tube to become coupled to the frame. Other applications are also described.
