Abstract
An electrosurgical system includes an RF current generator, a handle body, and an end effector in mechanical communication with the handle body. The end effector has a first jaw including a first electrode having a first electrode surface in electrical communication with a first terminal of the generator. The end effector also includes a second jaw including a second electrode having an essentially planar second electrode surface in electrical communication with a second terminal of the generator The first jaw includes at least one feature configured to apply an amount of a compressive force to a tissue compressed between the at least one feature and the second electrode surface that differs from an amount of a compressive force applied to the tissue compressed between the first electrode surface and the second electrode surface when the first jaw is placed in a proximate position to the second jaw.
