In an electromagnetic interference (EMI) filter terminal for an active
implantable medical device (AIMD), an insulated and shielded RF telemetry
pin is provided to prevent re-radiation of unwanted stray signals,
including the telemetry signal itself, to adjacent sensitive circuits or
lead wires. The invention provides for an EMI filter terminal assembly
for an AIMD including a radio frequency (RF) telemetry pin antenna
extending therethrough. The RF telemetry pin antenna includes a
conductive shield extending over a portion of the RF telemetry pin
antenna in non-conductive relation with the telemetry pin, and
conductively connected to a ground associated with the AIMD. The assembly
may also include an insulation tube between the RF telemetry pin antenna
and the conductive shield covering a portion of the RF telemetry pin
antenna.
