An electrosurgical generator (1) comprises a source of radio frequency (R.F.) energy, at least a pair of output terminals for connection to a bipolar electrosurgical instrument (3) and a pulsing circuit for the source. The generator (1) delivers to the electrosurgical instrument (3) an amplitude-modulated RE power signal in the form of a succession of pulses. The electrosurgical generator (1) has a blended mode comprising a rapidly alternating sequence of a first cutting mode and a second coagulation mode. The first cutting mode comprises pulses (11) having a predetermined voltage amplitude and a first pulse width, and the second coagulation mode comprises pulses (13) having a similar voltage amplitude but a second smaller pulse width. |
