    摘要： A surgical instrument comprising an end effector, the end effector comprising first and second opposing jaw members, wherein at least one of the first and second jaw members are moveable such that the first and second jaw members are transitionable between open and closed positions. The first jaw member may comprise a permanent magnet. The second jaw member may also comprise a magnet (e.g., permanent or soft). The magnetic motive force between the magnets of the first and second jaw members may attract each other to thereby reduce the external force required to transition the first and second jaw members to the closed position. In addition, the magnets may be configured to repeal each other to thereby aid in opening the jaw members.

    摘要： An electrosurgical surgical instrument can comprise a handle and an end effector, wherein the end effector can comprise first and second jaws which can be opened and closed in order to capture tissue therebetween. In various embodiments, the first and second jaws can comprise one or more electrodes configured to apply a voltage across the tissue, wherein one or both of the first and second jaws can include a plurality of electrodes each comprised of a positive temperature coefficient material having a different switching temperature. The electrical resistances of the electrodes can increase significantly once the temperature of the electrodes exceed their switching temperatures and, owing to the increased electrical resistance, the flow of current through the electrodes can be reduced and/or prevented. In various circumstances, the different switching temperatures of the electrodes can allow some of the electrodes to switch off before the other electrodes.

    摘要： An electrosurgical surgical instrument can comprise a handle and an end effector, wherein the end effector can comprise first and second jaws which can be opened and closed in order to capture tissue therebetween. In various embodiments, the first and second jaws can comprise one or more electrodes configured to apply a voltage across the tissue, wherein at least one of the electrodes can comprise a conductive material positioned within a non-conductive, or high-resistance, material. In use, current flowing through the conductive material can heat the conductive material and cause it to evaporate and leave behind the non-conductive material. In such circumstances, the current flowing through the electrode may cease or may be substantially reduced.

    摘要： Systems and methods are disclosed for therapeutically heating a target zone of a collagenous support tissue within a patient body. In exemplary embodiments, the present invention provides electronically determining an acceptable or unacceptable contact condition between an energy source and a first tissue layer disposed proximally to the target zone. Upon determining an acceptable contact condition, the target zone is irradiated or otherwise heated for a finite time period with energy. A determination of an unacceptable contact condition causes cessation of irradiating.
