Abstract: A controller implantable within the body of a patient as part of a left ventricular assist device (LVAD) system and a method therefore are provided. According to one aspect, the controller includes processing circuitry configured to receive inputs from at least one of: at least one internal component of the LVAD system, at least one external component of the LVAD system, and at least one clinicians device, and determine a charging rate for charging a battery of the LVAD system internal to the patient based on at least one of the received inputs.

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: 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.

Abstract: A system comprises processing circuitry and memory comprising program instructions that, when executed by the processing circuitry, cause the processing circuitry to: apply a first set of rules to first patient parameter data for a first determination of whether sudden cardiac arrest of a patient is detected; determine that a one or more context criteria of the first determination are satisfied; and m response to satisfaction of the context criteria, apply a second set of rides to second patient parameter data for a second determination of whether sudden cardiac arrest of the patient is detected. At least the second set of rules comprises a machine learning model, and the second patient parameter data comprises at least one patient parameter that is not included m the first patient parameter data.
