Abstract: A method of controlling operation of an implantable blood pump includes attempting to restart a stopped implantable blood pump for a predetermined number of attempts with either power from an internal battery of a controller in communication with the implantable blood pump or transcutaneous energy transfer system (TETS) power in communication with the internal battery and the implantable blood pump. Following the predetermined number of attempts, the method includes pausing attempting to restart the implantable blood pump and begin attempting to recharge the internal battery with TETS power.

Abstract: In an implanted medical device system, an internal controller, external power transmitter and methods for performing battery conditioning are disclosed. According to one aspect, an internal controller includes processing circuitry configured to cause conditioning of an internal battery of the internal controller responsive to a direction from an external power transmitter in radio communication with the internal controller.

Abstract: Techniques are described for initiating a change to rules used by a medical device to identify a plurality of episodes based on a determination that an amount of the plurality of episodes classified as a classification for which transmission of the episode data from the medical device to the computing device was unnecessary satisfies at least one criterion.

Abstract: A method of managing a speed of implantable blood pump. The implantable blood pump is in communication with an internal battery and a transcutaneous energy transfer system (TETS). The method includes starting the pump at a programmed set speed. The speed of the pump is decreased from the programmed set speed to a minimum set speed if either a capacity of the internal battery is less than a predetermined reserve level and TETS power is unavailable, or there is insufficient TETS power to maintain the programmed set speed. The speed of the pump is progressively decreased from the programmed set speed if there is insufficient power to maintain the programmed set speed.

Abstract: An external power transmitter of an implanted medical device system such as a left ventricular assist device (LVAD) system and a method therefore are provided. According to one aspect, a method includes transitioning from applying a first external coil current limit to applying a second external coil current limit to limit current of an external coil coupled to the external power transmitter, the transitioning being based on at least one of an intent to enter a free mode of operation of the implanted medical device system, an existence of an alarm condition, and an existence of transcutaneous energy transfer system (TETS) power transfer.
