The distal closure portion is configured to sealingly engage one of the left or right side of a septal wall, the proximal closure portion is configured to sealingly engage the other of the left or right side of the septal wall, and the waist section is configured to be positioned and centered in an atrial septal defect between the left and the right septal wall.

Abstract: A blood pump (20) includes a stator assembly comprising a motor stator (52), a fluid inlet (24), and a fluid outlet (26). A rotor assembly includes a motor rotor (54) and an impeller (40) rotatable about an axis (44) to move fluid from the inlet (24) to the outlet (26). An outflow sheath (300) directs the flow along the outside of the pump (20).

Abstract: Material testing under variable heat and load while continuously monitoring crack formation is provided using an apparatus that permits thermal control somewhat uniformly over a conductive sample, while permitting a controlled load to be applied to the sample in tensional or flexural modes. Thermographic imaging of a sample in situ within a standard thermo-mechanical fatigue (TMF) test rig or other heat and load test apparatus is used to detect and monitor cracks as they form. A 360° sample view is possible. Image analysis software may identify, count and/or characterize cracks. Thermographic images may be analyzed to determine a sample temperature, e.g. for temperature feedback control. Essentially passive thermography is used with an inductive heating coil that surrounds at least 60% of a length of the sample, with at least two windings, the windings having thickness and pitch so that at least half the sample is in view.

Abstract: A pump (100) includes a pump housing (200) having a fluid inlet (114) and a fluid outlet (116). An impeller (252) is disposed within the pump housing (200) and is rotatable about an axis (156) to move fluid from the inlet (114) to the outlet (116). A flexible drive spring (270) connects the impeller to a rotating drive mechanism (312). The spring (270) transmits torque to the impeller (252) from the drive mechanism (312) and preloads the impeller against a surface (232) of the pump housing (200).

Abstract: An embodiment consistent with the invention is an apparatus for and method of enabling a securing strap to reliably secure a container. The apparatus restrains the movement of the strap on the container. The apparatus has a hook portion having an opening disposed to engage the upper portion of a container and a loop portion disposed to be below the hook portion. The loop portion comprises an opening for receiving a strap therethrough, and includes a section disposed to prevent downward motion of a strap within the opening.
