A bipolar endoscopic needle knife may an elongate tubular member and a dome-shaped bipolar electrode assembly coupled to a distal end of the elongate tubular member. The bipolar electrode assembly may include an active electrode portion coupled to an active path of the bipolar endoscopic needle knife, a return electrode portion coupled to a return path of the bipolar endoscopic needle knife, and an insulating electrode portion configured to insulate the active electrode portion from the return electrode portion. When integrated together, the active, return, and insulating electrode portions may form a dome-shaped outer surface of the bipolar electrode assembly.
