    Abstract: Apparatus & 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 translation: 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。

    Abstract: Apparatus and methods are provided for placing and advancing a diagnostic or 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: Methods and apparatus for securing and deploying tissue anchors are described herein. A tissue manipulation assembly is pivotably coupled to the distal end of a tubular member. A reconfigurable launch tube is also pivotably coupled to the tissue manipulation assembly, which may be advanced through a shape-lockable endoscopic device, a conventional endoscope, or directly by itself into a patient. A second tool can be used in combination with the tissue manipulation assembly to engage tissue and manipulate the tissue in conjunction with the tissue manipulation assembly. A deployment assembly is provided for securing engaged tissue via one or more tissue anchors, the deployment assembly also being configured to disengage the anchors endoluminally or laparoscopically by applying thermal energy through at least one suture cutting element disposed along the deployment assembly.
