Abstract: This disclosure is directed to techniques for detecting and mitigating inaccurate sensing in a medical system. In some examples, one or more sensors of the medical system may include at least one electrode configured to sense an impedance of a portion of a patient's body proximate to the electrode and processing circuitry of the medical system may detect an inaccuracy in the data corresponding to the one or more patient physiological parameters based upon data including at least the sensed impedance of the portion of the patient body; correct at least a portion of the inaccuracy in the data corresponding to the one or more patient physiological parameters; and generate, for display on a display device, output data indicating the inaccuracy in the data corresponding to the one or more patient physiological parameters.

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: A system includes an implantable medical device and processing circuitry. The implantable medical device includes an accelerometer and sensing circuitry. The processing circuitry obtains, during a calibration period, a first motion signal from the accelerometer. The processing circuitry determines a motion threshold based on the first motion signal. The motion threshold relates to an amount of motion of the patient that is significant for treatment of the health condition of the patient. The processing circuitry obtains, during a collection period, a second motion signal from the accelerometer. Responsive to the second motion signal satisfying the motion threshold, the processing circuitry stores data related to the treatment of the health condition of the patient.

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: A method of managing multiple power sources for an implantable blood pump includes operating the implantable blood pump with both power from an internal battery, the internal battery being disposed within an implantable controller and in communication with the implantable blood pump, and with transcutaneous energy transfer system (TETS) power in communication with the implantable blood pump, if TETS power is available.

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.
