1. A medical device identification system comprising:

  • a medical device; and

    an identification tag coupled to the medical device, the identification tag including an RFID chip and an electrical circuit, the electrical circuit including at least one electrically conductive wire defining a first attachment region attached to the RFID chip at a first RFID location, and the at least one electrically conductive wire further defining a second attachment region, a third attachment region, and a fourth attachment region, the second attachment region attached to the RFID chip at a second RFID location that is spaced from the first RFID location, the electrical circuit defining a path between the first attachment region and the second attachment region, the third attachment region positioned on the path between the first attachment region and the second attachment region, and the fourth attachment region positioned on the path between the third attachment region and the second attachment region;

    wherein

         1) the system defines a first configuration in which the first attachment region is in electrical communication with the second attachment region along the electrical circuit, and a second configuration in which the first attachment region is electrically isolated from the second attachment region along the electrical circuit,

         2) the RFID chip is in a first state when the system is in the first configuration, and the RFID chip is in a second state different than the first state when the system is in the second configuration, and

         3) when the system is in the first configuration the third attachment region and the fourth attachment region are each attached to the medical device, and when the system is in the second configuration the third attachment region and the fourth attachment region are separated by a gap such that the third and fourth attachment regions are electrically isolated from one another.
