Abstract
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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
181 words
A system for controlling use of a device for treating a tissue region comprising a 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.
Claim 2
Independent Claim
181 words
A system for controlling use of a device for treating a tissue region comprising a 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.
Claim 3
Dependent Claim
71 words
A system according to claim 1 wherein the processing function causes the controller to create a table by registering unlike identification codes in memory as they are downloaded by the reader and to enable operation of the device when a new identification code is registered in the table, and wherein the operating system displays a first image to prompt input to create the table for the device using the processing function.
Claim 4
Dependent Claim
65 words
A system according to claim 2 wherein the processing function causes the controller to disable operation of the device when the given identification code matches an identification code in the table, and wherein the operating system displays a second image, different than the first image, to prompt exchange of the device when operation of the device is disabled as a result of the processing function.
Claim 5
Dependent Claim
26 words
A system according to claim 2 wherein the processing function causes the controller to register in the table, a time period of use of the device.
Claim 6
Dependent Claim
63 words
A system according to claim 4 wherein the processing function causes the controller to disable operation of the device when the time period of use exceeds a prescribed period, and wherein the operating system displays a second image, different than the first image, to prompt exchange of the device when operation of the device is disabled as a result of the processing function.
Claim 7
Dependent Claim
17 words
A system according to claim 1 wherein the device applies radio frequency energy to the tissue region.
Claim 8
Independent Claim
179 words
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.
Claim 9
Independent Claim
179 words
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.
Claim 10
Dependent Claim
59 words
A method according to claim 7 wherein the viewable image generating step generates a first image to prompt input to process the identification code for a given device according to the pre-programmed rules and a second image, different than the first image, to prompt exchange of the device when operation of the device is prevented by the pre-programmed rules.
Claim 11
Dependent Claim
19 words
A method according to claim 7 wherein the pre-programmed rules register a time period of use of the device.
Claim 12
Dependent Claim
29 words
A method according to claim 9 wherein the pre-programmed rules cause the controller to disable operation of the device when the time period of use exceeds a prescribed period.
Claim 13
Dependent Claim
19 words
A method according to claim 7 wherein the device, during use, applies radio frequency energy to the tissue region.
