## Abstract

A usage key card is adapted to be handled separate from a tissue treatment device. The usage key card has a storage medium formatted to contain an identification code, which is unique to the usage key card. The usage key card is also adapted to be read by a reader separate from the device. The storage medium is also formatted, when inserted into the reader, to retain data generated pertaining to operation of the device.

## Claims

### Claim 1

A controller linked to a radiofrequency generator and governing power levels and duration that radiofrequency is distributed to electrodes of a treatment device operatively connected to the generator, the controller evaluating a storage medium associated with the treatment device to either enable or not enable use of the device, the controller constructing and maintaining in memory a use table containing prior identification codes associated with particular treatment devices and previously registered by the controller and added to the use table, the controller adding to its registry an identification code of the treatment device operatively connected thereto if absence of prior use of the device is determined, and not adding to its registry the identification code of the treatment device if already in its registry, for each identification code a time record of a period of use of the treatment device being maintained by the controller to reflect the time period which energy was applied to the treatment 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.

### Claim 2 (depends on 1)

The controller of claim 1, wherein the storage medium is adapted to be read by a reader separate from the device.

### Claim 3 (depends on 1)

The controller of claim 1, wherein the controller governs delivery of fluid.

### Claim 4 (depends on 1)

The controller of claim 1, wherein the controller includes an input/output device which receives feedback information.

### Claim 5 (depends on 1)

The controller of claim 1, wherein the input/output device includes a graphical user interface to graphically present processing information to a physician.

### Claim 6 (depends on 4)

The controller of claim 4, wherein the feedback information is received from temperature sensors for processing by the controller to govern application of fluid.

### Claim 7 (depends on 5)

The controller of claim 5, wherein the feedback information is received from temperature sensors for processing by the controller to govern application of fluid.

### Claim 8 (depends on 1)

The controller of claim 1, wherein the controller governs removal of aspirated material.

### Claim 9 (depends on 3)

The controller of claim 3, wherein the controller governs removal of aspirated material.

### Claim 10 (depends on 5)

The controller of claim 5, wherein the graphical user interface displays changes depending on a treatment procedure using the device.

### Claim 11 (depends on 1)

The system of claim 1, wherein the operation of the device is disabled if characteristics of the device are incompatible with characteristics of the controller.

### Claim 12 (depends on 10)

The system of claim 10, wherein the operation of the device is disabled if characteristics of the device are incompatible with characteristics of the controller.
