    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: 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.
