A power delivery approach for delivering power to an electrosurgical vessel sealer when the jaws of the sealer surround tissue to be desiccated. Power delivery commences at a starting point that is at least 40 Joules and then decreases over a first predetermined period of time to a predetermined minimum power level to provide approximately 15 Joules in total. When the predetermined minimum power level is reached, power is then continuously increased over a second predetermined period of time to fully desiccate the tissue. Power delivery is terminated prior to over-desiccation of the tissue.
