    摘要: 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.

    摘要: An endoscopic system includes a sheath having a flexible sheath body. A tip is attached to a distal end of the sheath body. A handle is attached to the proximal end of the sheath body. A steerable section may be provided in the sheath adjacent to the tip. Steering controls may then be provided on the handle for steering the steerable section. Lumens extend from the tip to the handle. The distal end of each lumen is sealed to the tip. Bodily fluids can only enter into the lumens and not other areas within the sheath. In some embodiments, a shapelock assembly has an elongated hollow body positionable within the sheath body. The shapelock body may be switched between generally rigid and flexible conditions. The sheath provides a sterile barrier around the shapelock body. The shapelock assembly can be readily reused and the sheath may be disposable. In other embodiments, the flexible sheath has a composite construction that provides improved torque transmission capabilities.
