    摘要： A charging system for an implantable medical device having a secondary coil. The charging system includes an external power source having at least one primary coil, a modulation, circuit operatively coupled to the primary coil and capable of driving it in a manner characterized by a charging parameter, and a sensor in communication with the modulation circuit and capable of sensing a condition indicating a need to adjust the charging parameter during a charging process. The parameter may be varied so that data sensed by the sensor meets a threshold requirement, which may be based on a patient preference, a government regulation, a recommendation promulgated by a health authority and/or a requirement associated with another device carried by the patient. In one embodiment, the regulation dictates maximum magnetic field exposure, and a field limiting circuit is employed to adjust the charging process.

    摘要： This disclosure describes a chopper mixer telemetry circuit for use in a wireless receiver. The receiver may be located in an implantable medical device (IMD) or external programmer. The chopper mixer telemetry circuit may include a mixer amplifier that operates as a synchronous demodulator to provide selective extraction of wireless signals received from a transmitter while suppressing out-of-band noise that can undermine the reliability of the telemetry link between an IMD or programmer and another device. The mixer amplifier may utilize parallel signal paths to convert the received telemetry signal into an in-phase (I) signal component and a quadrature (Q) signal component and recombine the I and Q signal components to reconstruct the total signal independently of the phase mismatch between the transmitter and receiver. Each signal path may include a chopper-stabilized mixer amplifier that amplifies telemetry signals within a desired band while suppressing out-of-band noise.

    摘要： Techniques associated with a universal recharging device for recharging a power source of implantable medical devices (IMDs). The recharging device includes an interface to allow an antenna assembly to be removably coupled. The antenna assembly has a primary coil and a corresponding sense coil. The sense coil has a configuration that is selected based on the configuration of the primary coil. The sense coil is adapted to prevent voltage across the primary coil from exceeding a maximum voltage amplitude allowable with the recharging device. The maximum voltage amplitude may be selected based on a maximum magnetic field strength to which a patient is to be exposed. In one embodiment, the maximum voltage amplitude is programmable.
