A method and device for incising tissue from the gastrointestinal tract are described. The device is an electrosurgical cutting device. The electrosurgical cutting device includes a catheter and multiple electrically conductive cutting wires extending through a lumen of the catheter. The wires are movable between a retracted position and an extended cutting position. The wires form a divergent configuration in the extended cutting position. The electrosurgical cutting device may be loaded into an endoscope and which is then maneuvered to the target tissue site to be incised. Manipulating a handle assembly extends the wires into a divergent cutting configuration. Electrical current is applied causing the wires to incise tissue from the target site.
