Abstract:
1. An implantable medical device of the type adapted to provide a therapy to the body and/or to monitor a physiologic condition and to communicate with an external medical device by telemetry transmissions comprising: a hermetically sealed housing enclosing a telemetry transceiver, the enclosure housing having first and second major sides joined by minor sides separating the major sides apart, at least first and second minor sides joined at a minor side junction and extending substantially orthogonally away from the side junction; a telemetry antenna feedthrough attached to the hermetically sealed housing at a distance along the first minor side from the side junction having a telemetry feedthrough pin coupled at a feedthrough pin inner end to the telemetry transceiver and having a feedthrough pin outer end; a header formed of dielectric material comprising a first header segment attached to and extending along the first housing side from a point adjacent to the telemetry antenna feedthrough to the side junction and a second header segment enclosing header components attached to and extending along the second minor side from the side junction; and an elongated telemetry antenna extending from a telemetry antenna free end to a telemetry antenna fixed end that is attached to the telemetry feedthrough pin outer end, the telemetry antenna comprising a first antenna element supported by the first header segment to extend along the first minor side at a first spacing from the first minor side and a second antenna element supported by the second header segment to extend along the second minor side at a second spacing from the second minor side to the telemetry antenna free end.
