摘要: Apparatus and methods for positioning and securing anchors are disclosed herein. The anchors are adapted to be delivered and implanted into or upon tissue, particularly tissue within the gastrointestinal system of a patient. The anchor is adapted to slide uni-directionally over suture such that a tissue plication may be cinched between anchors. A locking mechanism, either within the anchor itself or positioned proximally of the anchor, may allow for the uni-directional translation of the anchor while enabling the anchor to be locked onto the suture if the anchor is pulled, pushed, or otherwise urged in the opposite direction along the suture. This uni-directional anchor locking mechanism facilitates cinching of the tissue plication between the anchors, and it may be utilized in one or several anchors in cinching a tissue fold.

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.
摘要翻译: 本文描述了用于优化锚固力的装置和方法。 在固定组织褶皱时,通过利用具有可扩张臂的组织锚来避免直接位于锚固件正下方的组织的过度压缩,所述组织锚构造成使锚和组织之间的接触面积最小化。 当锚固件处于其膨胀构型时,将负载施加到锚固件,直到其被最佳地构造成适应一定范围的偏转,同时锚固件本身对组织施加基本恒定的力。 可以使用各种装置,例如止动件,弹簧构件,保险丝,应变计等来指示锚固件何时被偏转到最佳范围内的预定水平。 此外,影响锚固特征的其他因素包括例如改变锚的臂或支柱的数量,臂的定位,臂的构型,套环的长度等。

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.
