1. A system for controlling delivery of energy to divide tissue comprising:
- an electrosurgical instrument having an electrically energizable electrode which communicates energy to the tissue; and
a generator to supply the energy to the electrosurgical instrument which supplies the energy to the tissue in a first pulse to react the tissue, in slow pulses to create a desiccation line until impedance at the tissue has reached a predetermined threshold, and in rapid pulses to divide the tissue across the desiccation line.

Abstract
System and method for controlling delivery of energy to divide tissue are disclosed. The system comprises an electrosurgical instrument having an electrically energizable cutting element which communicates electrical energy to the tissue and a generator to supply the energy to the electrosurgical instrument which supplies the energy to the tissue in a first pulse to react the tissue, in slow pulses to create a desiccation line until impedance at the tissue has reached a threshold, and in rapid pulses to divide tissue across the desiccation line.
