Graphical user interface for monitoring and controlling use of medical devices
First Claim
1. A system for controlling use of a device for treating a tissue region comprisinga controller to control operation of the device, a reader to download information to the controller, a usage key card adapted to be handled separate from the device and comprising a storage medium formatted to contain an identification code unique to the usage key card that, upon reading by the reader, is downloaded to the controller, the controller including a first data state prior to downloading of the identification code and a processing function for processing the identification code and enabling operation of the device if the identification code correlates in a pre-established manner with the first data state, the processing function operating, in response to enabling operation of the device, to change the first data state to a second data state that prevents subsequent operation of the device in response to downloading of the identification code, a display screen, and an operating system to generate a viewable image on the display screen that changes in response to processing of the identification code by the processing function.

Abstract
A device for treating a tissue region is supplied with a separate usage key card. The usage key card comprises a storage medium, which is formatted to contain an identification code unique to the usage key card. The usage key card is adapted to be read by a remote reader, to download the identification code for processing by a controller for the device. Processing of the identification code by the controller either enables or disables operation of the device according to prescribed criteria. A viewable image is generated on a display screen that changes in response to processing of the identification code.

7. A method for controlling use of a device for treating a tissue region comprising the steps of
providing a usage key card for the device adapted to be handled separate from the device and comprising a storage medium formatted to contain an identification code unique to the usage key card, reading the usage key card by a reader separate from the device to download the identification code to a controller for the device, the controller having a first data state prior to downloading of the identification code, causing the controller to process the identification code by pre-programmed rules to enable operation of the device if the identification code correlates with the first data state, changing, according to pre-programmed rules, the first data state to a second data state in response to enabling operation of the device, the second data state preventing a subsequent operation of the device in response to downloading of the identification code, and generating a viewable image on a display screen that changes in response to processing of the identification code according to the pre-programmed rules.
