  • Patent number: 9872997
    Abstract: A wireless charger system for inductively charging a rechargeable battery of an implantable pulse generator (IPG) implanted in a human body is provided. A charging coil in the charger is wirelessly coupled to a receiving coil of the IPG to charge the rechargeable battery. An end-of-charge (EOC) circuit continuously monitors the reflected impedance from a reflected impedance sensor and determines the end of charge when a predetermined pattern of the reflected impedance corresponding to an EOC signal from the IPG is received. Advantageously, receiving the EOC signal through the charging coil eliminates the need to provide a separate communication circuit in the IPG that communicates with the charger.

  • Patent number: 9867540
    Abstract: An inductive sensor system for remote powering and communication with an analyte sensor (e.g., a fully implantable analyte sensor). The system may include an analyte sensor and transceiver. The system may be ferrite-enhanced. The transceiver may implement a passive telemetry for communicating with the analyte sensor via an inductive magnetic link for both power and data transfer. The link may be a co-planar, near field communication telemetry link. The transceiver may include a reflection plate configured to focus flux lines linking the transceiver and the sensor uniformly beneath the transceiver. The transceiver may include an amplifier configured to amplify battery power and provide radio frequency (RF) power to a transceiver antenna.

  • Patent number: 9867994
    Abstract: An implantable medical device system includes an implantable medical device for providing stimulation therapy and two external power sources. A first external power source is used to power the implantable medical device when the stimulation therapy is low energy therapy. For example, the first external power device may be utilized to periodically recharge a battery in the implantable medical device. The second external power device may be utilized to power the implantable medical device when the stimulation therapy is high energy therapy. The second external power device may be a disposable patch that is affixed to a patient's skin to provide continuous power to the implantable medical device. The implantable medical device may communicate data to such a power device to cause it to adjust a strength of the charging field that it generates.

  • Patent number: 9855429
    Abstract: A system for delivering an electrical stimulation pulse to tissue comprises a controller-transmitter and a receiver-stimulator. The controller-transmitter includes circuitry having an energy storage capacitor. The capacitance of the energy storage capacitor is adjusted to improve the efficiency of energy delivered from the receiver-stimulator to tissue by modifying the geometry of an acoustic drive burst from the controller-transmitter.

  • Patent number: 9808634
    Abstract: The disclosed invention varies the width of the energy pulses with constant frequency and constant amplitude to regulate the amount of energy transferred from an energy transmitting device placed outside a patient to an energy receiver inside the patient. The pulse width is achieved with a modulation technique, PWMT, to control the amount of energy transferred from the external energy transmitting coil in the system to the implanted receiver. The PWMT is used to digitally vary the amount of power from the power amplifier that drives the transmitting coil. Compared to previous analog systems a PWM system is a great deal more efficient and can easily be controlled from a digital domain system such as a microprocessor.

  • Patent number: 9773610
    Abstract: An antenna arrangement for transmitting energy is described. The antenna arrangement includes a planar array of two or more rectangular loop antennas, adapted to transmit energy at low frequencies via non-radiative resonant coupling and at high frequencies via radiative coupling. The low frequencies correspond to a wavelength with half of the wavelength being larger than the longest rectangular loop antenna dimension and the high frequencies correspond to a wavelength with half of the wavelength being approximately equal the longest rectangular loop antenna dimension. The antenna arrangement also includes a feeding network connected to the planar array, which includes a phase shifting means for providing a phase difference between signals at the high frequencies to be transmitted by different rectangular loop antennas of the planar array, whereby the amount of phase difference is related to the distance of the rectangular loop antennas to a focal point in the near-field of the planar array.
