The end effector assembly includes jaw members movable from a first position in spaced relation relative to one another to at least one subsequent position wherein the jaw members cooperate to grasp tissue therebetween. Each of the jaw members includes a sealing plate that communicates electrosurgical energy through tissue held therebetween. One or more of the sealing plates includes one or more springs, the sealing plate is configured to slowly flex to accommodate pressure applied to the tissue until a specified closure pressure is obtained based upon at least one of tissue type and tissue thickness.
