    摘要： Methods and apparatus for performing endoluminal procedures are described herein. An endoluminal tissue manipulation assembly is disclosed which provides for a stable endoluminal platform and which also provides for effective triangulation of tools. Such an apparatus may comprise an optionally shape-lockable elongate body defining a longitudinal axis and adapted for endoluminal advancement in a patient body, at least one articulatable visualization lumen disposed near or at a distal region of the elongate body, the at least one articulating visualization lumen being adapted to articulate off-axis relative to a longitudinal axis of the elongate body, and at least one articulatable tool arm member disposed near or at the distal region of the elongate body, the at least one articulatable tool arm member being adapted to articulate off-axis and manipulate a tissue region of interest.

    摘要： Apparatus and methods for transgastric tissue manipulation are described herein. Procedures are performed transgastrically through a trocar or insert, e.g., to create tissue plications and approximating those plications towards one another for accomplishing gastroplasty procedures. The trocar is positioned through the abdominal wall of the patient and into the stomach. A multi-lumen insertion tool is positioned within the trocar and comprises one or several channels, e.g., two, three, or more channels as practicable, through the single insertion tool. Each of the channels is aligned and individually sealable with a reversible seal which allows for insertion or removal of a tool therethrough without comprising sealing of the entire trocar or port. A proximal section of the shafts comprise a flexible section to allow for the flexing of each respective control handle away from one another such that the surgeon can manipulate the tools without interference between the handles.

    摘要： Apparatus and methods are provided for placing and advancing a diagnostic of 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.

    摘要： 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 rotateable to allow grasping, elevation and more complex manipulation of tissue.
