1. An implanted medical device (“
- IMD”
) telemetry device comprising;
an electrically conducting structure;
an antenna located proximate to said electrically conducting structure; and
a receiver coupled to said antenna, said receiver being configured to receive IMD signals via said antenna, said antenna being configured to account for surface current cancellation caused by induced surface current on said electrically conducting structure.

Abstract
A telemetry component according to an embodiment of the invention, such as a programmer or a monitor for an implantable medical device (“IMD”), includes at least one radio frequency (“RF”) antenna that is configured to accommodate far-field telemetry between the telemetry component and the IMD. The RF antenna is shaped, sized, positioned, and otherwise configured to account for surface current cancellation caused by induced surface current on an electrically conductive surface of the telemetry component.
