An implantable medical device ("IMD") configured in accordance with an
example embodiment of the invention generally includes a housing, a
connector header block coupled to the housing, and an optional telemetry
antenna coupled to the header block. The optional antenna assembly is
suitably configured to support the intended IMD application (e.g., the
desired telemetry range, the intended IMD implant location, or other
practical considerations). The optional antenna assembly may be utilized
by itself or in cooperation with a permanent telemetry antenna of the
IMD. In one practical embodiment, the optional antenna assembly has a
connection end that is compliant with known pacemaker electrode lead
standards, which allows the IMD to leverage existing connection
methodologies.
