摘要： Apparatus and methods for optimizing anchoring force are described herein. In the securing tissue folds, over-compression of the tissue directly underlying the anchors is avoided by utilizing tissue anchor (10) having expandable arms (12) configured to minimize contact area between the anchor (10) and tissue. When the anchor (10) is in its expanded configuration, a load is applied to the anchor (10) until it is optimally configured to accommodate a range of deflection while the anchor (10) itself exerts a substantially constant force against the tissue. Various devices e.g., stops, spring member, fuses, strain gauges, etc., can be used to indicate when the anchor (10) has been deflected to a predetermined level within the optimal rang. Moreover, other factors to affect the anchor (10) characteristics include, e.g., varying the number of arms (12) or struts (12) of the anchor (10), positioning of the arms (12), configuration of the arms (12), the length of the collars (14, 16), etc.
摘要翻译：本文描述了用于优化锚固力的装置和方法。在固定组织折叠中，通过利用具有可扩张臂（12）的组织锚固件（10）来避免直接位于锚固件正下方的组织的过度压缩，所述组织锚固件被构造成使锚固体（10）和组织之间的接触面积最小化。当锚固件（10）处于其膨胀构型时，负载被施加到锚固件（10），直到其被最佳地构造成适应一定范围的偏转，同时锚固件（10）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（10）何时已经偏转到最佳范围内的预定水平。此外，影响锚（10）特征的其他因素包括例如改变锚（10）的臂（12）或支柱（12）的数量，臂（12）的定位，臂（12）的构型），项圈（14,16）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.

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 of positioned proximally of the anchor may allow for the uni-directional translation 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 the cinching of the tissue plication between the anchors and it may be utilized in one or several anchors in cinching a tissue fold.
摘要翻译：本文公开了用于定位和固定锚固件的装置和方法。锚固件适于被递送并植入到组织中，特别是患者胃肠系统内的组织中。锚固件适于在缝合线上单向滑动，使得组织褶皱可以在锚固件之间束紧。如果锚固件被拉动，推动或沿着缝合线沿相反方向被推动，锚固件本身内的定位器本身内的锁定机构可以允许单向平移，同时使锚固件能够锁定在缝合线上。这种单向锚定锁定机构有助于锚定器之间的组织褶皱收紧，并且可以在一个或多个锚定器中用于收紧组织折叠。
