1. An end effector, comprising:

  • a first jaw member comprising a first positively-angled tissue-contacting surface;

    a second jaw member comprising a second positively-angled tissue-contacting surface, wherein the first positively-angled tissue-contacting surface and the second positively-angled tissue-contacting surface define a tissue cutting zone;

    a cutting element;

    an elongate slot extending longitudinally through the tissue cutting zone, wherein the elongate slot is configured to receive the cutting element; and

    a distal zone defined by the first jaw member and the second jaw member that extends distally with respect to the tissue cutting zone, wherein the first positively-angled tissue-contacting surface and the second positively-angled tissue-contacting surface do not extend into the distal zone;

    wherein the first jaw member is movable relative to the second jaw member between an open position and a closed position, wherein a first gap is defined between the first jaw member and the second jaw member in the tissue cutting zone when the first jaw member is in the closed position, wherein a second gap is defined between the first jaw member and the second jaw member in the distal zone when the first jaw member is in the closed position, wherein the first gap is smaller than the second gap, and wherein the distal zone is configured to grasp a needle when the first jaw member is in the closed position;

    wherein at least one of the first jaw member and the second jaw member comprises at least one active electrode; and

    wherein the at least one active electrode is configured to deliver RF energy to tissue located between the first jaw member and the second jaw member when the first jaw member is in the closed position.
