A RF energy console controls RF energy output from a RF generator for sealing blood vessels. The energy console includes a processor that executes routines and a controller feedback circuit that, in combination, control the RF generator. Operation includes a heating stage outputting a RF ramping voltage and determining a decrease in measured current to less than a predetermined % percentage of a maximum measured and stored current value to advance to a sealing stage. Then, the voltage is controlled to maintain an increasing change in impedance until a change in current value approaches a flat curve indicating seal completion, which stops the RF generator output. To reseal or enhance a blood vessel seal, the energy console executes the same routines as in the initial sealing operation.
