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 at least one 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 upon detection of the predetermined condition; and
providing tension to the tissue during the second phase to separate the tissue.

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.

17. A method for controlling delivery of energy to seal and divide tissue, the method comprising:
-
applying energy to tissue through an electrosurgical forceps having at least one electrically energizable electrode which communicates 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 upon detection of the predetermined condition; providing tension to the tissue during the second phase to initiate separation of the tissue; determining the completion of the separation of the tissue; and terminating the application of energy to tissue upon determination of the completion of the separation of the tissue. - View Dependent Claims (20)
