A telemetry system and method includes an implantable medical device implanted in a body and an external communication device, e.g., a programmer. The implanted device includes a housing having transmitter/receiver circuitry positioned therein. The external communication device includes transmitter/receiver circuitry connected to an antenna thereof. The transmitter/receiver circuitry of the implanted device is electrically coupled to the body such that the body functions as an antenna for the implanted device to facilitate communication of data between the implanted device and the external communication device.

[ What is claimed is:] [1.] An implantable medical device telemetry method, the method comprising the steps of:providing an implanted device in a body, the implanted device including a housing having a transmitter positioned therein, and a body antenna that optimally adapts the body for use as an antenna;providing communication device external to the body, the external communication device including at least a receiver connected to an antenna;providing an output signal generated by the transmitter into the body via the body antenna external to the housing of the implanted device, wherein the output signal is modulated to include data, and further wherein the modulated output signal is propagated by the body to radiate electromagnetic waves representative of the modulated output signal in a near-field communication volume surrounding the body; andreceiving the radiated electromagnetic waves at the antenna of the external communication device when the antenna is positioned within the near-field communication volume and recovering the data therefrom by the receiver of the external communication device.
