Abstract
The invention relates to an implantable medical device system comprising an active medical device having or connected to at least one electrode and circuitry connected to the electrode. The active medical device comprises a telemetry unit. The circuitry connected to the electrode comprises at least one single conductor that provides a radio frequency antenna for the telemetry unit. The implantable medical device system further comprises at least one electronic filter that is arranged between the single conductor of circuitry connected to the electrode and the telemetry unit. The least one electronic filter comprises at least one inductor having a core that comprises a ferromagnetic material with saturating behavior when exposed to an external magnetic field.
