To simply/reliably transmit information of the electrode lead to the implant (with a low expenditure of energy), a hermetically sealed passive RFID label is embedded: in the insulating tube, and/or in the plug, or in an insulating body of a separate additional part connectable to the insulating tube or the plug. The RFID label has an RFID chip and an inlay antenna connected in an electrically conducting manner to the RFID chip. The inlay antenna is electromagnetically coupled to the at least one electrical conductor and the communication antenna. A corresponding method for identifying an electrode lead and a corresponding implant are also contemplated. ## Claims ### Claim 1 A method for identifying an electrode lead by means of an implant, the electrode lead comprising: a plug for connecting to the implant, at least one electrical conductor, an insulating tube that insulates the at least one electrical conductor, and a hermetically sealed passive RFID label embedded: in the insulating tube, and/or in the plug, or in an insulating body of a separate additional part that is connectable to the insulating tube or the plug, preferably in a positive fit, wherein the RFID label has an RFID chip and an inlay antenna connected in an electrically conducting manner to the RFID chip, wherein the inlay antenna is electromagnetically coupled to the at least one electrical conductor and the communication antenna, wherein the implant has a control device and an communication antenna connected to the control device, and wherein the implant is connected to the electrode lead, the method comprising the following steps: transmitting an electromagnetic query signal using the electrical conductor to be read and the communication antenna, wherein the query signal is configured such that the communication antenna and the electrical conductor together are operated as a bipolar antenna, wherein the query signal is produced by the control device connected to the electrical conductor to be read and the communication antenna; activating the RFID label by receiving the query signal by means of the inlay antenna of the RFID label and forwarding the received query signal to the RFID chip; processing the received query signal using the RFID chip, producing a corresponding electromagnetic reply signal using the RFID chip, and transmitting the reply signal by means of the inlay antenna of the RFID label; receiving the reply signal using the bipolar antenna comprising the communication antenna and the electrical conductor of the electrode lead to be read; and, processing the received reply signal forwarded to the control device in the control device. ### Claim 2 (depends on 1) The method according to claim 1, wherein the query signal is produced by the control device at regular and/or prespecifiable time intervals and/or after the occurrence of a prespecified event, after an electrode lead has been attached to the implant. ### Claim 3 (depends on 1) The method according to claim 1, wherein if two or more than two electrode leads are attached to the implant, wherein of these electrode leads one electrode lead is newly attached to the implant, the identification method for all attached electrode leads is executed successively for all attached electrode leads and in that each reply signal is compared to the information on electrode leads already stored in a memory device of the implant and, based on the result of the comparison, the information of the newly attached electrode lead is allocated to the socket of the implant connected to the new electrode lead.
