An end effector of an instrument is positioned in a patient. An ultrasonic blade of the end effector is positioned against tissue in the patient. The ultrasonic blade is activated to vibrate ultrasonically while the ultrasonic blade is positioned against tissue. At least one electrode of the end effector is positioned against tissue in the patient. The at least one electrode is activated to apply RF electrosurgical energy to tissue against which the at least one electrode is positioned against tissue.

Method of treating tissue using end effector with ultrasonic and electrosurgical features

An apparatus includes a body, a shaft assembly, and an end effector. The end effector includes an ultrasonic blade and a clamp arm assembly. The ultrasonic blade is in acoustic communication with an acoustic waveguide of the shaft assembly. The clamp arm assembly is pivotable toward and away from the ultrasonic blade. The clamp arm assembly includes a first electrode and a second electrode. The first and second electrodes are operable to cooperate to apply bipolar RF energy to tissue.
