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 This allows the anchor assembly to be advanced distally as well as withdrawn proximally within a deployment sheath while avoiding inadvertently ejecting an anchor.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: 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: The present invention provides methods for performing gastroplasty by 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 the endoluminal revision of previously performed obesity procedures which have failed are described. One or more endoluminal instruments may be advanced per-orally into the previously formed failed pouch where a number of different procedures can be performed. One or more tissue folds can be formed and secured to reduce the size of the pouch, or the stoma connecting the pouch to the intestinal tract can be reduced in size using endoluminally deployed tissue anchors. These procedures can be performed entirely from within the pouch lumen or upon the exterior surface of the pouch via transgastric entry of the instruments into the peritoneal cavity of a patient. Alternatively, the interior tissue within the pouch can be injured or sclerosed to shrink the pouch lumen. In another alterative, a length of the Roux limb can be shortened endoluminally to create a malabsorptive region.

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.
