    摘要： A system for inserting a collapsible blood pump into a patient. In some embodiments, the system includes an introducer, the introducer comprising an introducer hub and an introducer sheath extending distally from the introducer hub, the introducer sheath comprising an introducer sheath lumen, the introducer hub comprising a hub connector and a distal hub lumen surrounding a proximal end of the introducer shaft; and a transfer tool comprising a transfer sheath, the transfer sheath comprising a transfer sheath lumen having a diameter substantially equal to a diameter of the introducer sheath lumen and a transfer tool connector adapted to connect to the hub connector, a distal portion of the transfer sheath extending into the distal hub lumen when the transfer tool connector is connected to the hub connector.

    摘要： Provided is a left ventricular assist system that includes at least: a blood pump; and a controller that controls the rotation of a rotary body of the blood pump. The controller controls the blood pump such that a rotational speed of the rotary body is periodically switched between a first rotational speed and a second rotational speed that is larger than the first rotational speed with a transition time required for switching the rotational speed set to substantially 0 (zero). Periodic switching of the rotational speed of the rotary body is asynchronous with a cardiac cycle of a user, and the rotary body rotates substantially only at rotational speeds of two values consisting of the first rotational speed and the second rotational speed.

    摘要： A method of determining a presence of suction in a patient having an implantable blood pump from down-sampled log files. The method comprising calculating a waveform index for each of a plurality of flow rate data points from the down-sampled log files. The calculated waveform index is compared with a predetermined waveform index threshold. A non-suction trough baseline is calculated from the plurality of flow rate data points. A difference between a measured trough and a calculated non-suction trough baseline is compared with a predetermined threshold. The presence of suction for each of the plurality of flow rate data points is determined if the calculated waveform index is greater than the predetermined waveform index threshold and the difference between the measured trough and a calculated non-suction trough baseline is greater than the predetermined threshold.
