  • Implantable medical device with inductive antenna filter
    Patent number: 8428744
    Abstract: This disclosure describes techniques for reducing, and possibly eliminating, adverse effects caused by signals induced on an inductive antenna of an implanted medical device by varying magnetic fields from a source of interference, such as the gradient magnetic fields applied during an MRI procedure. For example, the implantable medical device includes an inductive antenna that receives signals via inductive coupling, a filter circuit that attenuates signals induced on the inductive antenna by varying magnetic fields generated from a source of interference and substantially passes signals induced on the inductive antenna by varying magnetic fields generated by an expected source and a telemetry module that processes the signals from the filter circuit.
