Abstract: Method and systems control a rotational speed of a blood pump during ventricular diastole. A method includes controlling a blood pump in accordance with a first segment operational mode. A controller monitors the blood flow rate through the blood pump. The controller determines, based on the blood flow rate, whether continued controlling of the blood pump per the first segment operational mode would result in the blood flow rate through the blood pump being less than a target minimum blood flow rate. In response to a determination that continued controlling of the blood pump per the first segment operational mode would result in the blood flow rate through the blood pump being less than the target minimum blood flow rate, the controller controls the rotational speed of the blood pump so that the blood flow rate through the blood pump is approximate to the target minimum blood flow rate.

Abstract: 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.

Abstract: Blood pump systems and methods employ transmission of electrical energy and data over a percutaneous cable. A method of transmitting electrical energy and data over a percutaneous cable includes transmitting electrical energy over a first pair of conductors of a percutaneous cable for use in powering an implantable blood pump. Transmission of electrical energy over the first pair of conductors is discontinued to accommodate data transmission over the first pair of conductors. Transmission of the data over the first pair of conductors is discontinued to accommodate recommencement of transmission of electrical energy over the first pair of conductors for use in powering the implantable blood pump.

Abstract: A blood pump system includes a first implantable housing, an implantable blood pump independent from the first implantable housing, and a percutaneous extension. The first implantable housing includes a rechargeable power storage device. The implantable blood pump supplements the pumping function of a heart. The rechargeable power storage device supplies electrical power to the implantable blood pump. The percutaneous extension is coupled to the rechargeable power storage device and adapted to traverse the skin. The percutaneous extension is configured to releasably connect to an external power supply adapted to provide power for recharging or supplementing the rechargeable power storage device to power the implantable blood pump.
