摘要： Disposable shapelocking systems are disclosed herein. A shapelock assembly generally comprises an elongate body defining at least one lumen therethrough for advancement of an endoscope or other endoscopic instruments therethrough. A handle assembly can be actuated to compress nested links against one another to transition the elongate body from a flexible state to a rigid shape-locked state. One or more of the nested links can be made from a particular thermoplastic either alone or in combination with one or more reinforcing structures. Such structures can include a reinforcing ring integrated with the link on an inner, outer, or lower surface of the link. Alternatively, the link can be coated or layered to enhance its strength. Additionally, different portions of the shapelock body can be made from different types of links depending upon the loads imparted upon the various portions of the shapelock body.

摘要： 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.

摘要： Interlocking tissue anchor apparatus and methods are described herein. In creating tissue folds within the body of a patient, a tissue manipulation assembly may generally have an elongate tubular member, an engagement member slidably disposed through the tubular member and a distal end adapted to engage tissue via a helical member, tissue stabilizing members positioned at the tubular member distal end which are adapted to stabilize tissue therebetween, and a delivery tube pivotable about the tissue stabilizer. Anchor assemblies can be delivered via the tissue manipulation assembly into or through the tissue. The anchors can incorporate various temporary interlocking features or spacing elements between one another to ensure that an anchor is not prematurely ejected from the needle assembly. This allows the anchor assembly to be advanced distally as well as withdrawn proximally within a deployment sheath while avoiding inadvertently ejecting an anchor.

摘要： Systems, devices and methods for endoscopic procedures are provided involving accessing and manipulating tissues beyond the capabilities of traditional endoscopic instruments. Embodiments of the systems include an elongated main body which has one or more independently shape-lockable sections and a variety of instruments which are either built in to the main body or advanceable through lumens which extend through the main body. Such instruments may include scopes, suction instruments, aspiration instruments, tool arms, plicators, needles, graspers, and cutters, to name a few. The ability to steer and shapelock specific sections of the main body enables access to target locations which are typically challenging to reach and provides a stabilized platform to perform a desired procedure at the target location.

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： Methods and apparatus for maintaining sterility during transluminal procedures are described. The sterility is achieved by making use of a membrane in either the form, e.g., of a sheath, cap or umbrella to keep the instruments (endoscopes, overtubes, etc.) sterile while being advanced through lumens in the body and into the various cavities. Methods, such as vacuum acquisition, mechanical tissue anchoring, etc., of the underlying tissue followed by incision of the tissue with, e.g., a needle knife, can be utilized to gain access to the various cavities. It is expected that this procedure will provide the desired level of sterility for transluminal procedures.

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： Apparatus and methods are provided for controlling pressurization of a body cavity by controlling the rate and magnitude of pressurization during insufflation and/or exsufflation. In one variation, a pump may be used to either draw suction or to pressurize a body cavity. The pump may be connected to a controller that controls one or more regulators and/or valves for regulating pressurization. The controller preferably is programmable to allow a medical practitioner to input and/or rapidly alter desired pressurization parameters. In another variation, one or more pumps may be provided to simultaneously and independently control pressurization of multiple body cavities, such as a patient's stomach and peritoneal cavity.
