IMPLANTABLE MEDICAL DEVICE CONFIGURED TO ESTABLISH A COMMUNICATION LINK TO ANOTHER IMPLANTABLE MEDICAL DEVICE

An implantable medical device, contains control circuitry and communication circuitry for communicating with another implantable medical device. The communication circuitry includes a transmission unit and a reception unit. The transmission unit, for establishing a communication link with the other implantable medical device, is configured to transmit a multiplicity of transmit communication signals, wherein each transmit communication signal is associated with a dedicated sub-range of a predefined frequency range. The reception unit is configured to receive a response communication signal in response to a transmit communication signal. The control circuitry is configured to determine whether a response communication signal in response to a transmit communication signal associated with a dedicated sub-range has been received, and to establish the communication link based on the determination.
