A cryogenic catheter includes an outer flexible member having at least one cryogenic fluid path through the flexible member. The processing means comprise an interpreter provided with conversion rules, arranged in the form of \u201cscripts\u201d associated with the various primary event formats, and arranged to convert, by means of these rules, primary data received in one of the primary formats into secondary data in the secondary format which can be interpreted by the management device. At the exits of each shop area where an intermediate product is completed one reporting point serves as exit point in order to report the completion of an intermediate production step. By this configuration, the number of power feed lines for the overall system can be significantly reduced, and common bodies not distinguished for the main and sub bodies can be used as the sensor bodies, whereby the cost can be reduced and inventory management can be facilitated.
