1. A method for sealing a vessel comprising:
supplying electrical energy to an ultrasonic surgical instrument having an end effector and a transducer coupled to the end effector, when the end effector is grasping the vessel;
sensing parameters of the vessel when the end effector achieves a predetermined velocity;
estimating a size of the vessel based on the sensed parameters;
controlling the electrical energy based on maintaining a predetermined initial heating rate of heating the vessel until a predetermined amount of energy corresponding to the estimated size of the vessel has been delivered; and
controlling the electrical energy to seal the vessel based on a predetermined heating rate curve of heating the vessel after the predetermined amount of energy corresponding to the estimated size of the vessel has been delivered.
