Abstract
A device carries an 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.
Claims11
A system for treating a tissue region comprising
- a device including a usage regulating mechanism having a logic state being operable to be set to either a logic state of one or a logic state of zero, and
- a reader to sense the logic state and enabling operation of the device if the sensed logic state is a pre-established one of the logic state of one and the logic state of zero, the reader further operating, in response to enabling operation of the device, to change the sensed logic state to the other one of the logic state of one and the logic state of zero to prevent subsequent operation of the device.
A system for treating a tissue region comprising
- a controller, and
- a device including a use register that senses time-of-use of the device and inputs the time-of-use to the controller,
- 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 time period and to disable operation of the device if the time-of-use equals or exceeds the prescribed maximum time period.
