1. A method for controlling delivery of energy to seal and divide tissue, the method comprising:

  • applying energy to tissue in a first phase through an electrosurgical forceps having a first electrically energizable electrode and a second electrically energizable electrode;

    detecting a predetermined condition based on the application of energy to tissue during the first phase;

    applying energy to tissue during a second phase through the first and second electrically energizable electrodes upon detection of the predetermined condition;

    manipulating the first and second electrically energizable electrodes relative to the tissue to provide tension on the tissue during the second phase to separate the tissue;

    detecting a predetermined change in the energy applied to the tissue during the second phase, the predetermined change being indicative of tissue separation; and

    terminating the second phase upon detection of the predetermined change.
