An implantable medical device is disclosed comprising a conductive case； a charging coil within the case for receiving power from an external charger, the charging coil wound around an area having a first extent； and a telemetry coil within the case for receiving data from an external controller, or for transmitting data to the external controller, or for receiving and transmitting data from and to the external controller, the telemetry coil would around an area having a second extent, in which the second extent of the telemetry coil at least overlaps the first extent of the charging coil. The charging coil can be proximate to one side of a circuit board, with the telemetry coil is proximate to the other side. The implantable medical device further comprises a non-conductive header comprising at least one lead connector for coupling to an electrode lead.
