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.

Abstract
A method for controlling delivery of energy to seal and divide tissue includes applying energy to tissue in a first phase through an electrosurgical forceps having at least one electrically energizable electrode. The method also includes detecting a predetermined condition based on the application of energy to tissue during the first phase. The method also includes applying energy to tissue during a second phase upon detection of the predetermined condition and providing tension to the tissue during the second phase to separate the tissue.

18. A method for controlling delivery of energy to seal and divide tissue, the method comprising:
-
applying energy to tissue through an electrosurgical forceps having a first electrically energizable electrode and a second electrically energizable electrode which communicate the energy to the tissue in a first phase; 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 initiate separation of the tissue; determining the completion of the separation of the tissue based on a predetermined change in the energy applied to the tissue during the second phase; and terminating the application of energy to tissue upon determination of the completion of the separation of the tissue. - View Dependent Claims (19, 20)

21. A method for controlling delivery of energy to seal and divide tissue, the method comprising:
-
applying energy to tissue through an electrosurgical forceps having a first electrically energizable electrode and a second electrically energizable electrode which communicate the energy to the tissue during a first phase; detecting at least one of a tissue property and an energy property 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, at least one property of the energy applied to tissue during the second phase based on at least one of the tissue property and the energy property; manipulating the first and second electrically energizable electrodes relative to the tissue to provide tension to on the tissue during the second phase to separate the tissue; detecting a predetermined change in at least one of a property of the tissue and a property of the energy applied to the tissue during the second phase, the predetermined change being indicative of tissue separation; and terminating the application of energy to tissue upon detection of the predetermined change. - View Dependent Claims (22, 23, 24)
