NON-LINEAR JAW GAP FOR ELECTROSURGICAL INSTRUMENTS

An end effector for an electrosurgical instrument is disclosed which comprises a first jaw comprising a first energy delivery surface, a first distal end, and a first proximal end; and a second jaw comprising a second energy delivery surface, a second distal end, and a second proximal end, wherein the first energy delivery surface comprises a first curved portion that is outwardly curved, and the second energy delivery surface comprises a second curved portion that is inwardly curved. The first jaw or the second jaw is configured for pivotal movement between an open position and a closed position. In the open position, the first and second distal ends are separated apart. In the closed position, the first and second distal ends are in proximity. The end effector also comprises an electrically conductive member which protrudes from either the first or second jaw.
