    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： Methods and apparatus for performing endoluminal procedures are described herein. An endoluminal tissue manipulation assembly is disclosed which provides for a stable endoluminal platform and which also provides for effective triangulation of tools. Such an apparatus may comprise an optionally shape-lockable elongate body defining a longitudinal axis and adapted for endoluminal advancement in a patient body, at least one articulatable visualization lumen disposed near or at a distal region of the elongate body, the at least one articulating visualization lumen being adapted to articulate off-axis relative to a longitudinal axis of the elongate body, and at least one articulatable tool arm member disposed near or at the distal region of the elongate body, the at least one articulatable tool arm member being adapted to articulate off-axis and manipulate a tissue region of interest.
