    Abstract: Techniques for facilitating communication between an implantable medical device and an external device are provided. In one example, a method comprises broadcasting, via communication circuitry of an implantable device, a first set of advertisements at a first advertising rate according to a communication protocol. The method further comprises determining that detection circuitry of the implantable device detected voltage induced by an electromagnetic field at an interface between tissue of a patient and electrodes of the implantable device and in response to the detection of voltage induced by the electromagnetic field, broadcasting, via the communication circuitry, a second set of advertisements at a second advertising rate according to the communication protocol. The second advertising rate is greater than the first advertising rate.

    Abstract: Various embodiments of a system are disclosed. The system includes a sensing apparatus configured to monitor cardiac electrical activity of a patient and a computing apparatus operatively coupled to the sensing apparatus and configured to monitor cardiac electrical activity using the sensing apparatus to generate a cardiac signal over time, detect a pacing artifact in the cardiac signal, and determine to account for the pacing artifact when using the cardiac signal based on at least one pacing artifact characteristic of the pacing artifact in the cardiac signal. The computing apparatus is further configured to account for the pacing artifact when using the cardiac signal if it is determined to account for the pacing artifact.

    Abstract: An internal coil interface implantable within the body of a patient and configured to modulate a load on an internal coil, and a method therefore are provided. According to one aspect, processing circuitry of the internal coil interface is configured to predict a time of a first voltage level crossing by a voltage at a terminal of the internal coil for each of a plurality of successive windows each time the capacitance is switched into the modulated load circuit or each time the capacitance is switched out of the modulated load circuit. The process is also configured to adjust the predictions based on whether a previous prediction of a time of a first voltage level crossing for a window was later or earlier than a time at which the first voltage level crossing actually occurred.

    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 method and apparatus related to detecting the presence of a power transfer coil implanted in a patient are disclosed. According to the aspect, an external device of a medical implant system is provided, the external device having an external coil and processing circuitry. The processing circuitry is configured to monitor a resonance frequency associated with the external coil. When the resonance frequency changes as a distance between the external coil and an expected location of an internal coil, then the processing circuitry is configured to conclude that the internal coil has been detected. When the resonance frequency ramps up to a steady state value at a rate that falls below a rate threshold, then the processing circuitry is configured to conclude that the internal coil is connected to an internal load.
