    摘要： Apparatus for use with a percutaneous ventricular assist device (20) that comprises a self-expandable pump head (27) and that is configured to be delivered to a subject's left ventricle using a delivery catheter (143), while the pump head (27) is disposed in a radially-constrained configuration within the delivery catheter (143), the apparatus comprising: packaging (270) for the ventricular assist device, the packaging (270) being shaped to define: a pump-head chamber (274) in which the pump head (274) is packaged in a non-radially constrained configuration; and a surface (284) that is slanted downwards; and a catheter-securement piece (276) configured to secure a distal end of the delivery catheter to the surface (284) that is slanted downwards, such that the distal end of the catheter (273) is oriented in a downwards slant, the packaging (270) being configured such that the pump head (27) is configured to be radially constrained by being retracted into the distal end of the delivery catheter (143), while the distal end of the delivery catheter (143) is secured to the surface (284) that is slanted downwards.

    摘要： A method for manufacturing an impeller (50) is described. A structure (59) is formed having first and second bushings (64, 58) at proximal and distal ends of the structure, the first and second bushings (64, 58) being connected to one another by at least one elongate element. The elongate element is made to radially expand and form at least one helical elongate element (52). An elastomeric material is coupled to the helical elongate element (52), such that the helical elongate element (52) with the elastomeric material coupled thereto defines a blade of the impeller (50). Bonding of the elastomeric material to the helical elongate element (52) is enhanced in a manner that does not cause a protrusion from the effective edge of the impeller blade.

    摘要： 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; a distal thrust bearing (260) disposed within the frame (34), 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 a plurality of connecting struts (264) extending radially inwardly from the frame (34) to the distal thrust bearing (260) and coupling the thrust bearing (260) to the frame (34), the frame (34) and the connecting struts (264) being formed as a single integral body.

    摘要： A left-ventricular assist device (20) is described that includes a frame (34) defining a plurality of cells and having a generally cylindrical portion (38), a width (CW) of each of the cells within the cylindrical portion (38) as measured around a circumference of the cylindrical portion (38) being less than 2 mm. An inner lining (39) lines at least some of the cylindrical portion (38) of the frame (34). An impeller (50) is disposed inside the frame (34) such that at a location at which a span of the impeller (50) is at its maximum, a gap (G) between an outer edge of the impeller (50) and the inner lining (39) is less than 1 mm. The impeller (50) is stabilized with respect to the frame (34), such that, during rotation of the impeller (50), gap (G) is maintained and is substantially constant.
