1. A system for treating a tissue region comprisinga controller, anda device including a handle, an element within the handle holding a unique identification code, and a use register that senses prior use of the device and senses time-of-use of the device and inputs the time-of-use to the controller, the use register containing a digital value that changes upon use of the device, the use register including an output that generates the digital value upon prompting and an input which increments the digital value upon a period of use of the device to apply radio frequency energy, the use register further retaining a value reflecting an actual period of time during which energy is applied to the device;
- the controller including a processing function for processing the time-of-use to enable operation of the device if the time-of-use is less than a prescribed maximum of time period and to disable operation of the device if the time-of-use equals or exceeds the prescribed maximum time period;
the controller registering the unique identification code when the device is coupled to a controller, the controller further maintaining a use table containing prior identification codes that meet a criteria to be registered by the controller, the controller comparing the unique identification code of the device coupled thereto to the prior identification codes to detect an absence or a presence of a match, in the absence of the match the controller updates the use table by adding the unique identification code to the use table and enables use of a generator associated with the device, and in the presence of the match the controller does not add the unique identification code to the use table.

Abstract
A device carries a use monitoring element that possesses a state or condition that changes in response to use of the device and that is sensed when the device is presented for use. Reuse of the device is not permitted, if the use monitoring element indicates a prior use.
