Claim Text:
1. A control unit that is configured to control delivery of radio frequency (RF) energy to a medical device, the control unit comprising: switching circuitry configured to permit a first portion of the RF energy received from an RF generator to be output by the control unit to a medical device when configured in a closed state, and prevent the first portion of the RF energy from being output by the control unit to the medical device when configured in an open state; energy measurement circuitry configured to determine that an amount of the first portion of the RF energy delivered to the medical device has reached a threshold level, and switch the switching circuitry from the closed state to the open state upon a determination that an amount of the first portion of the RF energy has reached the threshold level; an output module configured to output at least one of: a first indication indicating a number of times an electrosurgical procedure is performed, a second indication indicating whether the first portion of the RF energy is being communicated through the control unit, or a third indication indicating an error associated with the electrosurgical procedure; power supply circuitry configured to, while the control unit is receiving the RF energy from the RF generator, convert a second portion of the RF energy to one or more power supplies, and supply a first portion of the one or more power supplies to the energy measurement circuitry and the output module; and an energy storage module configured to store a second portion of the one or more power supplies while the control unit is receiving RF energy from the RF generator, and when the control unit stops receiving the RF energy from the RF generator, power at least one of the output module or the energy measurement circuitry for a predetermined period of time using the stored second portion of the one or more power supplies.
