    Abstract: Apparatus and methods for optimizing anchoring force are described herein. In securing tissue folds, over-compression of the tissue directly underlying the anchors is avoided by utilizing tissue anchors having expandable arms configured to minimize contact area between the anchor and tissue. When the anchor is in its expanded configuration, a load is applied to the anchor until it is optimally configured to accommodate a range of deflections while the anchor itself exerts a substantially constant force against the tissue. Various devices, e.g., stops, spring members, fuses, strain gauges, etc., can be used to indicate when the anchor has been deflected to a predetermined level within the optimal range. Moreover, other factors to affect the anchor characteristics include, e.g., varying the number of arms or struts of the anchor, positioning of the arms, configuration of the arms, the length of the collars, etc.

    Abstract: 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.

    Abstract: 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.

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

    Abstract: Apparatus and methods for endoluminal advancement are described herein. A shape-lockable tissue anchoring assembly generally has an elongate body, a handle assembly, and an anchoring assembly positioned at or proximal to a distal tip of the elongate body. A distal portion of the elongate body may optionally be steerable or curvable. The anchoring assembly may include various expandable or projecting anchoring features to contact and retain tissue relative to the elongate body such that pleated tissue is temporarily immobile relative to the elongate body. This anchoring can be actuated simultaneously with or independently from shape-locking of elongate body. The anchoring assembly can be actuated simultaneously with the shape-locking of the elongate body. Alternatively, the steerable distal portion of the elongate body can be angled against the pleated tissue to retain it while the endoscope is advanced relative to the pleated tissue.
