The system includes an electrosurgical generator (20) adapted to supply energy at an output level to tissue. The electrosurgical generator (20) includes a microprocessor (25) adapted to generate a desired impedance trajectory having at least one slope. The target impedance 5 trajectory includes one or more target impedance values. The microprocessor (25) is also adapted to drive tissue impedance along the target impedance trajectory by adjusting the output level to substantially match tissue impedance to a corresponding target impedance value. The microprocessor (25) is further adapted to compare tissue impedance to a threshold impedance value and adjust output of the electrosurgical generator (20) when the 10 tissue impedance is equal to or greater than the threshold impedance. The system also includes an electrosurgical instrument (10) including at least one active electrode adapted to apply electrosurgical energy to tissue.1/3 20>；12 10 ELECTROSURGICAL GENERATOR FIG. 1 £20 24>；2- 2CONTROLLER 25S MICROPROCESSOR 26 22 MEMORY SENSOR CIRCUITRY FIG. 2
