Abstract: The present disclosure provides systems and methods for wirelessly charging an implantable medical device. An external charging device includes a coil, signal generating circuitry to drive current through the coil at a charging frequency to induce current in a second coil in the implantable medical device, monitoring circuitry to generate an output signal to monitor charging operations, and a comb filter. The comb filter is configured to apply filtering to the output signal to remove noise from the output signal, wherein the filtering is applied based on the charging frequency. The external charging device is configured to process the filtered output signal to detect a circuit state of charging circuitry of the implantable medical device during charging operations, and the external charging device is configured to vary the charging frequency based, in part, on detection of the circuit state of the charging circuitry of the implantable medical device.

Abstract: A system and method of quantifying, maintaining and managing the functional status and/or therapy settings of an IMD based on code path metrics is disclosed. The codebase of device firmware modules may be instrumented to obtain tracing data and timing metrics data corresponding to different code paths that may be taken when a device subsystem or associated functionality is accessed or activated. Code path metrics of actual code paths may be analyzed to detect a deviation from baseline code path metrics and generate a corresponding graduated response.
