Abstract: A system for minimizing misalignment notifications for a TETS having an implantable blood pump, an external controller having a power source and a processing circuitry, a transmission coil in communication with the external controller, a receiving coil configured for transcutaneous inductive communication with the transmission coil, and an implantable controller in communication with the receiving coil and the implantable blood pump. The implantable controller having a power source configured to receive power from the receiving coil. The processing circuitry may be configured to: operate in a first mode where an alert is generated when a power efficiency transfer between the transmission coil and the receiving coil is below a first predetermined threshold; and operate in a second mode where the alert is only generated when the power remaining in the power source for the implantable controller is below a first predetermined power source threshold.

Abstract: A TETS having an external controller having a power source, a transmission coil in communication with the external controller, a receiving coil configured for transcutaneous inductive communication with the transmission coil, and an implantable controller in communication with the receiving coil and an implantable blood pump. The implantable controller has a battery configured to receive power from the receiving coil and the external controller is configured to categorize power transfer states based on predetermined thresholds of efficiency and power demand, and user display states (associated with optional configurable notifications) based on the power transfer states and predetermined temperature thresholds of the transmission coil.

Abstract: A method, implantable medical system and an external system for communicating an alert signal via a transcutaneous energy transfer system (TETS), with or without the presence of transmission of the alert signal by an alternative wireless communication system, are disclosed. According to one aspect, a method in an implanted medical system includes obtaining the alert signal based on an occurrence of an event, and transmitting the alert signal from the implanted medical device to the external system via a TETS used to transfer power requests to the external system.

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 clinician's 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.
