  • Patent number: 10469963
    Abstract: An external portion of an auditory prosthesis includes magnets, electronics, and other components. In bone conduction auditory prostheses, reducing the amount of mass subject to vibrations in an auditory prosthesis has a positive effect on tuning of the device. One way of reducing such mass is to resiliently more massive components within the auditory prosthesis housing. Such resilient mounting reduces the dampening effect that these massive components have on vibrations generated by the prosthesis. When electronic components are suspended, feedback to said components is also reduced, resulting improved performance.

    Abstract: A method and system for supplying energy to an electrically operable medical device (100) implanted in a patient. Wireless energy is transferred from an external energy source (104) located outside the patient to an internal energy receiver (102) located inside the patient and connected to the medical device. An internal control unit (108) determines an amount of energy currently required for the operation of said medical device. A control signal is transmitted to the external energy source, reflecting the required amount of energy. An external control unit (106) controls the amount of transferred energy in response to the control signal, by adjusting the energy transfer efficiency from the external energy source to the internal energy receiver. The energy transfer efficiency is adjusted by adjusting the position of a primary coil, serving as the external energy source, relative to an implanted secondary coil, serving as the internal energy source.

  • Patent number: 10027157
    Abstract: A method for wirelessly charging a battery in an implantable medical device including the steps of: providing a receiver in the implantable medical device and providing a temperature sensor in the implantable medical device. The method also includes receiving, via the receiver, a wireless power signal from an external charger and converting the wireless power signal into a battery charge signal including power for recharging the battery. The method yet also includes sensing a temperature of the implantable medical device with the temperature sensor. The method further includes changing a current of the battery charge signal from a first non-zero current to a second non-zero current that is different from the first non-zero current. Changing of the current of the battery charge signal is based on the temperature sensed by the temperature sensor.

  • Patent number: 10010717
    Abstract: Electrical energy is transcutaneously transmitted at a plurality of different frequencies to an implanted medical device. The magnitude of the transmitted electrical energy respectively measured at the plurality of frequencies. One of the frequencies is selected based on the measured magnitude of the electrical energy (e.g., the frequency at which the measured magnitude of the electrical energy is the greatest). A depth level at which the medical device is implanted within the patient is determined based on the selected frequency. For example, the depth level may be determined to be relatively shallow if the selected frequency is relatively high, and relatively deep if the selected frequency is relative low. A charge strength threshold at which a charge strength indicator generates a user-discernible signal can then be set based on the determined depth level.

  • Patent number: 9950179
    Abstract: Devices, systems, and techniques for delivering trial stimulation therapy to a patient are disclosed. A trial neurostimulator (e.g., an IMD) may be implanted within a patient to deliver stimulation therapy during a relatively short trial period of time. This IMD may include limited circuitry and be powered by an external power source to minimize the size of the IMD within the patient. The IMD may include a non-hermetic housing capable of protecting the IMD circuitry for the trial period of time. In one example, the IMD may include a secondary coil configured to generate an electrical signal in response to a magnetic field generated by an external primary coil, circuitry configured to generate a stimulation signal in response to the electrical signal, and a non-hermetic implantable housing configured to encase or otherwise house the secondary coil and the circuitry.

  • Patent number: 9849298
    Abstract: The disclosed system for providing closed loop charging between an external charger and an implantable medical device such as an IPG involves the use of reflected impedance modulation, i.e., by measuring at the external charger reflections arising from modulating the impedance of the charging coil in the IPG. During charging, the charging coil in the IPG is periodically pulsed to modulate its impedance. The magnitude of the change in the coil voltage produced at the external charger ?V as a result of these pulses is assessed and is used by the controller circuitry in the external charger as indicative of the coupling between the external charger and the IPG. The external charger adjusts its output power (e.g., Icharge) in accordance with the magnitude of ?V, thus achieving closed loop charging without the need of telemetering coupling parameters from the IPG.

    Abstract: An external controller is disclosed for communicating with an external trial stimulator (ETS) for an implantable medical device. The external controller is programmed with a battery algorithm able to assist a clinician in choosing a suitable implant for the patient based on battery performance parameters estimated for a number of implants during an external trial stimulation phase that precedes implantation of the implant. The algorithm is particularly useful in assisting the clinician in choosing between a rechargeable-battery implant or a primary-battery implant for the patient.

  • Patent number: 9786432
    Abstract: An external transmitter inductive coil can be provided in, on, or with a belt designed to be placed externally around a part of a body of a patient. An implantable device (such as a VAD or other medical device) that is implanted within the patient's body has associated with a receiver inductive coil that gets implanted within that part of the patient's body along with the device. The externally-located transmitter inductive coil inductively transfers electromagnetic power into that part of the body and thus to the receiver inductive coil. The implanted receiver inductive coil thus wirelessly receives the inductively-transferred electromagnetic power, and operates the implant.
