A method of treating tissue is provided herein. The method comprises positioning an end effector in a first position in proximity to tissue, wherein the end effector has one or more first thermal elements and one or more second thermal elements and an energy delivery configuration,activating the one or more first thermal elements, absorbing energy from tissue via the one or more first thermal elements, wherein the energy absorbed is in a first predetermined volume based on the energy delivery configuration, activating the one or more second thermal elements, delivering energy to tissue via the one or more second thermal elements, wherein the energy delivered is in a second predetermined volume based on the energy delivery configuration, and generating a predetermined treatment zone based on the first predetermined volume and the second predetermined volume.
