Abstract: An implantable medical device having a hollow housing and a connector housing connected (e.g., rigidly) together, each containing electrical components. The components contained in the hollow housing include a receiver for wireless communication. The components contained in the connector housing include an antenna electrically connected to the receiver and configured to receive electromagnetic waves having a frequency greater than 100 MHz. The receiver/antenna allows the receipt of data in the MICS frequency band. The electrical components arranged in the connector housing additionally include a resonant circuit having a coil and a capacitor which is inductively coupled to the antenna. The resonant circuit is matched to magnetic alternating fields in a frequency range between 5 kHz and 50 MHz, preferably having a resonance frequency between 5 kHz and 50 MHz. The resonant circuit is suitable for data communication in the near field of the implantable medical device via magnetic alternating fields.

Abstract: Embodiments include an implantable medical device (IMD) that includes a control unit, a permanent memory for a device identifier IID, a memory unit that stores a device identifier EID of an external device, a near-field data communication unit and a far-field data communication unit. The control unit, jointly with the near-field data communication unit, detects a third device in the near-field region of the IMD and transmits the device identifier IID of the IMD to the third device. The control unit, following a near-field data communication with a third device, checks any messages received via the far-field data communication unit as to whether the messages include a far-field start message and a device identifier IID of the IMD that corresponds to the device identifier stored in the permanent memory. The control unit sends a far-field response message, which includes the device identifier IID and the device identifier EID.
