    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: Methods for performing gastroplasty include reducing the effective volume or cross-sectional area of the stomach via approximation of gastric tissue. Such reduction preferably is achieved endoluminally, either with or without laparoscopic ports. In one variation, a sleeve, pouch, Magenstrasse and Mill, Vertical Banded Gastroplasty (“VBG”), etc.,is formed within the stomach by approximating opposing anterior and posterior segments or ridges of the stomach wall at locations inferior to the gastroesophageal junction. In another variation, opposing walls of the stomach are approximated at a plurality of substantially random locations to reduce an effective volume of the stomach. In yet another variation, both a sleeve and random approximations are formed, the random approximations preferably disposed in a portion of the stomach excluded by the sleeve. In still another variation, opposing walls of the stomach are approximated over significant lengths at random or specified locations.

    摘要: Methods and apparatus for off-axis visualization 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.

    摘要: An endoluminal surgical instrument has first and second steering controls on a handle. A flexible shaft attached to the handle has a distal steerable end including a first link and a second link separated by a plurality of intermediate links. First and second steering elements, such as pairs of steering wires, are linked to first and second steering controls and to the first and, second links. One or more of the links is pivotable through an angle of at least 30 degrees relative to an adjoining link. The set back position of the second steering elements from the first steering elements, and the pivoting capability of the links allows the steerable end to be steered into a small bend radius. This makes the instrument highly maneuverable for use in endoluminal surgery, such as incision-less surgery of the stomach.
