An implantable stimulation device comprises one or more electrodes, a receiving antenna coil, a transmitting antenna coil and a control circuit. The receiving antenna coil is in a first layer, the transmitting antenna coil is in a second layer and the control circuit is in a third layer between the first and second layers. The control circuit is configured to receive signals using the receiving antenna coil, transmit signals using the transmitting antenna coil, and deliver stimulation signals to the one or more electrodes. The receiving antenna coil, the transmitting antenna coil and the control circuit are contained in a hermetically sealed container.
