摘要： A method for outputting a combined power source alarm for an implantable blood pump includes determining a status for each of first and second power sources of the blood pump. A combined power source alarm based on the statuses of the first and second power sources is outputted. A method for generating an alarm based on fault detections in a mechanically assisted circulation system includes processing a series of fault detection indications to classify a fault as active or inactive. An alarm is generated if the fault is active for more than a predetermined amount of time.

摘要： The present invention generally relates to ventricular assist device power monitoring and conservation. In some embodiments, a pump controller may transition the pump to operate in a power-saving operational mode when a power source and/or a power source condition indicate a need to conserve power. In some embodiments, when the power source is an emergency battery and when the emergency battery has powered the pump for an extended period of time, the controller may signal the pump to operate in the power saving-operational mode. In some embodiments, when a low power hazard condition is triggered by signals from one or more external power sources, the controller may signal the pump to transition to the power-saving operational mode if the condition lasts for an extended period of time. In some embodiments, the controller may trigger the power-saving mode when the emergency backup battery is below a voltage threshold.

摘要： Methods, systems, and devices for an updatable 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 system controller can initiate the update process and can provide the update to the blood pump. Upon initiation of the update process, the control unit can stop the rotary motor. While the rotary motor is stopped, the blood pump can be updated. At the completion of the update, the rotary pump can be restarted.

摘要： An implantable blood pump includes a control unit storing patient specific settings. The control unit is configured to store patient specific settings. The patient specific settings can be used to determine a target operating speed for the blood pump and/or a target operating mode for the blood pump. The patient specific settings can include at least one of an operating mode for the pump, a set speed for the pump, a lower speed limit for the pump, a patient hematocrit value, a patient hematocrit date, a patient blood density, and a periodic log rate for event and periodic data.
