摘要： A system and a method for starting a rotor of an implantable blood pump are described. For example, a blood pump system includes a rotary motor having a stator and a rotor. The rotor has permanent magnetic poles for magnetic levitation of the rotor, and the stator has a plurality of pole pieces arranged circumferentially at intervals. The blood pump system includes a controller configured to control a start phase of the rotor, wherein the start phase is prior to the rotor being positioned in a predefined geometric volume for pumping blood and wherein the start phase includes performing a rotation of the rotor by an angle larger than an angle corresponding to a quarter of an angular distance between two neighboring magnetic poles of the rotor.

摘要： An instability detection algorithm for an implantable blood pump may include determining a target position of a rotor of the pump, the rotor having permanent magnetic poles for magnetic levitation of the rotor, calculating a positional displacement of the target position from a predefined origin of a coordinate system of a housing of the pump, and calculating, during a rotation of the rotor, geometric deviations of a current position of the rotor from the target position.

摘要： Methods, systems, and devices for an adaptable blood pump are disclosed herein. The blood pump can be part of a mechanical circulatory support system that can include a system controller and the blood pump. The blood pump can include a rotary motor and a control unit that can communicate with the system controller. The blood pump can determine when communication with the system controller is established or has been lost. The blood pump can retrieve one or several back-up parameters when communication with the system controller has been lost, and can operate according to these back-up parameters.
