Abstract: A medical device system includes a medical device configured to be carried by a patient and a plurality of controllers capable of controlling operation of the medical device. Each controller has an active state in which the controller is in communication with, and controls the operation of, the medical device, and a passive state in which the controller is not controlling operation of the medical device. At any given time only one of the plurality of controllers will be in the active state and a remainder of the plurality of controllers will be in the passive state. The active controller may be configured to continually communicate with the remainder of passive controllers, without using the medical device as an intermediary, to update the information stored in the memories of the passive controllers to match the information in the memory of the active controller.

Abstract: A method of controlling an implantable blood pump of a living patient. The method includes receiving one or more pump signals indicating at least one from the group consisting of a motor speed of the blood pump, power supplied to the blood pump, and differential pressure exerted by the blood pump. One or more medication signals is received indicating whether the patient has taken a medication. The flow rate of blood based on a combination of the one or more pump signals and the medication signals is determined. At least one from the group consisting of increasing and decreasing power is supplied to the pump in response to the determined flow rate.
