    摘要： An attachment device has a sewing ring frame and a locking mechanism movably mounted on the sewing ring frame. The locking mechanism includes a biasing element projecting from the outer surface of the sewing ring frame and a slide substantially co-planar to the sewing ring frame. The slide further includes a first mating member. Additionally, the locking mechanism includes at least one guide member overlapping the slide and a locking pin disposed between the slide and the sewing ring frame. The biasing element is movably coupled to the locking pin and the slide and is transitionable between a first configuration in which the first mating member is in a disengaged position to a second configuration in which the first mating member is in an engaged position.

    摘要： The application pertains to a blood pump system, in particular a ventricular assist device, VAD, the system including a blood pump, which comprises: a housing, including an inlet and an outlet, preferably an axial influx and a tangential outflow; a motor actuator, wherein the motor includes a plurality of motor coils (for driving an impeller); an impeller, wherein the impeller is located in the housing and includes a plurality of rotor magnets.
    The system further comprises a drive line; and a control unit for controlling operation of the pump, the control unit configured to: operate the motor, such that the impeller rotates around an axis; and measure the rotor position in a direction along the axis using at least one of the plurality of the motor coils.

    摘要： A plug for coupling to a suture ring may include a distal portion extending from a distal end toward a proximal end of the plug, and a proximal portion coupled to the distal portion and extending from the proximal end toward the distal end of the plug. The distal portion may include a distal cylindrical body centered on a central axis of the plug and configured for being received at least partially within a central opening of the suture ring, and the distal cylindrical body may have a first outer diameter. The proximal portion may include a proximal cylindrical body centered on the central axis of the plug and configured for extending over a proximal end of the suture ring when the distal cylindrical body is received at least partially within the central opening of the suture ring, and the proximal cylindrical body may have a second outer diameter that is greater than the first outer diameter.

    摘要： An apical cuff axial compression assembly including a ring member for coupling an apical cuff of a Ventricular Assist Device pump, to left ventricular apical tissue. Tissue anchors are employed to engage with the ring member and the apical cuff to exert direct or axial compression of the ring member to the apical cuff and to the left ventricular apical tissue. A first variant includes an axial compression ring and a plurality of openings to accommodate the tissue anchors. A second variant includes a segmented axial compression ring composed of a plurality of arcuate members, which may be contiguous or joined to each other or not. Each of the plurality of arcuate members has at least one tissue anchor opening passing there through.
