Abstract:
1. A system comprising a storage medium associated with a device for treating a tissue region, the device including a handle, a catheter tube extending from the handle, a temperature sensor and a basket including a plurality of spines, the spines carrying an electrode for delivering treatment energy to a tissue site, the temperature sensor sensing temperature near a distal end of the electrode, the basket being movable between a non-expanded low profile condition and an expanded condition and the electrode being movable from a first position to an extended position, the storage medium formatted to contain an identification code uniquely assigned to the device for registration of the device if absence of prior use is determined in terms of a time period of use of the device less than a maximum prescribed time period, for each identification code a time record of such period of use being maintained by a controller to reflect the time period which energy was applied to the device to ascertain the time period of previous use to maintain the time record separate from the device, and the time record maintained by the controller updated and maintained by the controller as further use occurs, such further use being limited to a time period remaining, and a reader and a controller, the storage medium read by the reader and the reader inputting the identification code to the controller to enable the controller to add to its registry the downloaded identification code if not already in its registry.
