  • Patent number: 8529437
    Abstract: A surgical tool having proximal and distal ends and adapted to transverse a curved passageway comprises an end effector disposed on the distal end of the surgical tool, the end effector having a first body section and a second body section and a releasable connector joining the end effector first body section with the end effector second body section. The connector is operable to reversibly engage the first and second end effector body sections in a first fixed position and in a second movable position. The surgical tool further comprises an actuation device for moving the first and second end effector body sections from the first fixed position to the second movable position. The end effector is adapted to maneuver through a larger radius of curvature in the second movable position than in the first fixed position.

  • Patent number: 8007494
    Abstract: A surgical instrument and safety system comprises a safety shield having an inner surface and an outer surface, an active conductor having a first end adapted to connect with an electrode and a second end adapted to connect with an electrosurgical generator, the electrosurgical generator including contact quality monitoring circuitry, an insulator surrounding the active conductor and disposed between the active conductor and the safety shield, and a circuit interruption device in electrical communication with the safety shield. The circuit interruption device is adapted to couple to the contact quality monitoring circuitry of the electrosurgical generator and disable the flow of current to the electrode upon the occurrence of a fault condition.

  • Patent number: 7465302
    Abstract: A system and method for performing an electrosurgical procedure are disclosed. The method includes applying an active electrode to a patient and placing a return electrode on the patient so as to create a current path in tissue of the patient between the active electrode and the return electrode. A conductive element, which is operatively coupled to the active electrode, is coupled to a reference voltage with a low impedance path and a voltage is imparted to the active electrode so as to generate current in the current path. Any undesirable current flow that would otherwise flow from the active electrode to the reference voltage through the patient is limited to reduce a risk of harm to the patient.

  • Patent number: 7422589
    Abstract: A system and method for performing an electrosurgical procedure are disclosed. The method includes obtaining information indicative of at least one physical characteristic of the patient and generating a reference voltage that is derived, at least in part, from the information. The reference voltage is coupled to a body of the electrosurgical apparatus, and the reference voltage is generated to a level so as to limit any difference between a voltage of the patient and a voltage of the body of the electrosurgical apparatus. In variations, the reference voltage is varied on an ongoing basis so as to adapt the reference voltage to one or more changing physical characteristics of the patient.
