    Abstract: An overtube for use with an endoscopic surgical instrument. In various embodiments, the overtube may comprise a substantially flexible helically wound continuous member forming a series of helical coils that define a hollow passage sized to receive a portion of the endoscopic surgical instrument therethrough. The coils may be configured to selectively interlock with each other to stiffen the overtube. An actuation system may be employed to steer the overtube and selectively stiffen it. Some embodiments include a second substantially flexible helically wound member that may be selectively wound between the first substantially flexible helically wound member or segments thereof.

    Abstract: In various surgical techniques, a bipolar forceps can be used to seal a vessel in two locations such that the vessel can be incised at a location positioned intermediate the two seal locations. The bipolar forceps can include a cutting element which can be configured to incise the vessel. In various embodiments, the cutting element can include a sharp edge which can be moved relative to the vessel. In at least one embodiment, the cutting element can be electrically connected to a source of energy. The bipolar forceps can include first and second electrodes positioned within first and second jaw members, respectively, wherein at least one of the jaw members can include a substantially tapered profile and can be configured to pull the vessel away from the surrounding soft tissue. Such jaw members can include ridges, teeth, and/or a textured outer surface configured to grip the soft tissue and/or vessel. A bipolar forceps including a first electrode, a second electrode, and a conductor operably connected to an electrical source, wherein the conductor can be selectively placed in electrical communication with the first electrode when the first electrode is moved between open and closed positions. The conductor can include a contact end which is not in contact with the first electrode when the first electrode is in its open position. In such an open position, the first electrode may not be in electrical communication with the electrical source and, as a result, current may not flow through the first electrode. The first electrode can be moved into its closed position such that the first electrode is in contact with the contact end of the wire. In such a closed position, the first electrode may be in electrical communication with the electrical source allowing current to flow through the first electrode.
