    Abstract: Systems, devices and methods are provided for endoscopic procedures involving tissue manipulations beyond the capabilities of traditional endoscopic instruments. Embodiments of the systems include an elongated main body having a scope therethrough and at least one steerable tool arm which extends from the distal end of the main body. In preferred embodiments, the system includes two tool arms, each arm steerable to form a curve laterally outward which then bends laterally inward so that the arms form an angular shape. In addition, end effectors extend from the distal ends of each tool arm for use in manipulation of tissue. The angular shape brings the end effectors together in view of the scope for cooperative movements which are continuously visible by the surgeon. In addition, the tool arms may be steerable in any additional direction and may be rotatable to allow grasping, elevation and more complex manipulation of tissue.

    Abstract: Apparatus and methods are provided for placing and advancing a diagnostic or therapeutic instrument in a hollow body organ of a tortuous or unsupported anatomy, comprising a handle, an overtube, a distal region having an atraumatic tip. The overtube may be removable from the handle, and have a longitudinal axis disposed at an angle relative to the handle. The overtube may be selectively stiffened to reduce distension of the organ caused by advancement of the diagnostic or therapeutic instrument. The distal region permits passive steering of the overtube caused by deflection of the diagnostic or therapeutic instrument while the atraumatic tip prevents the wall of the organ from becoming caught or pinched during manipulation of the diagnostic or therapeutic instrument.

    Abstract: Methods for percutaneous hernia repair may include inserting a needle end of an anchor tool through a first tissue edge on a first side of a hernia defect opening. A first anchor is deployed with a first suture attached to the first anchor and running back through or along the anchor tool and outside of the patient's body. The needle end of the anchor tool is withdrawn from the first tissue edge. The first suture is separated from the anchor tool. The needle end of an anchor tool is inserted through a second tissue edge and a second anchor is deployed, with a second suture attached to the second anchor and running back through or along the anchor tool and outside of the patient's body. The sutures are tensioned and cinched or knotted.
