Implantable medical device without a wire-wound coil configured to receive wireless power from an external charger

An implantable medical device (IMD) configured to wirelessly receive power from an electromagnetic field, comprising:

• a case housing control circuitry for the IMD, wherein at least a portion of the case is conductive and comprises a conductive case portion, and wherein a case current is formed in the conductive case portion in response to the electromagnetic field;
• power reception circuitry inside the case;
• a non-conductive header affixed to the case;
• and
• a first electrical connection and a second electrical connection to divert at least some of the case current as a power current to the power reception circuitry, wherein at least one of the first electrical connection and the second electrical connection comprises an antenna portion in or on the non-conductive header, resulting in at least one antenna portion in or on the non-conductive header,
• wherein the power reception circuitry is configured to use the power current to provide power to the IMD.
