Electrosurgical forceps including sensor feedback facilitating tissue sealing and/or determination of a completed seal

An electrosurgical system, comprising:

• an end effector assembly including first and second jaw members each defining an electrically-conductive tissue-contacting surface, at least one of the first or second jaw members movable relative to the other between a spaced-apart position and an approximated position for grasping tissue between the tissue-contacting surfaces thereof, at least one of the first or second jaw members including a sensor configured to sense at least one property associated with the grasped tissue;
• an electrosurgical generator including a controller and an energy output, the energy output configured to supply electrosurgical energy to the tissue-contacting surface of at least one of the first or second jaw members for conduction through the grasped tissue to seal the grasped tissue, the controller configured to:
• receive the at least one sensed property;
• determine at least one condition of collagen within the grasped tissue based upon the at least one sensed property;
• and
• control the energy output based upon the determined at least one condition of the collagen within the grasped tissue.
