Inventor： Luis Ortiz Hernandez , Santhosh Seetharaman , Seil Oh , Edward Lundberg , Nicholas Sachs , Hongxuan Zhang , William Winstrom
CPC classification number: A61N1/3787 , A61N1/37223 , A61N1/37247
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 wireless charger device is configured to charge an implantable medical device (IMD). A patient controller obtains one or more power parameters from the charger device during charging of the IMD. The patient controller estimates a temperature range of the IMD using the one or more power parameters from the charger device and compares to a heating threshold. The patient controller then determines whether one or more spacers are recommended in response to the comparison. The one or more spacers are removably attached to the wireless charger device and are configured to lay in a position between the wireless charger device and a patient's skin to increase a charging path.
