MRI-safe implantable lead assembly: United States Patent 9974949

By: Thompson, David L.

A medical device includes a pulse generator and a filter. The pulse generator is configured to generate a stimulation signal and to provide the stimulation signal to tissue of a patient via an implantable lead assembly. The filter is configured to couple to the implantable lead assembly. A combined impedance of the implantable lead assembly and the filter with respect to a current induced by an external electro-magnetic field satisfies an impedance threshold when the external electro-magnetic field has a first frequency and when the external electro-magnetic field has a second frequency. The combined impedance has a peak impedance value when the external electro-magnetic field has a third frequency that is between the first frequency and the second frequency.
