    摘要: The present invention provides methods and apparatus for endoluminally performing gastroplasty. In one variation, the apparatus comprises a sizing tube, and a steerable guide that may be reversibly disposed within the sizing tube. In another variation, the sizing tube and steerable guide are integrated into a single device. In one method of utilizing the apparatus, a pouch is endoluminally formed within a patient's stomach, thereby partitioning or reducing the stomach and restricting the flow of food therethrough. The pouch may form a Vertical Banded Gastroplasty or Magenstrasse and Mill in an endoluminal fashion. Advantageously, the sizing tube or steerable guide may be used to properly size the endoluminal pouch.

    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: Apparatus and methods are provided for placing and advancing a diagnostic or therapeutic instrument in a hollow body organ of a tortuous or unsupported anatomy, comprising a handle, an overtube, a distal region having an atraumatic tip. The overtube may be removable from the handle, and have a longitudinal axis disposed at an angle relative to the handle. The overtube may be selectively stiffened to reduce distension of the organ caused by advancement of the diagnostic or therapeutic instrument. The distal region permits passive steering of the overtube caused by deflection of the diagnostic or therapeutic instrument while the atraumatic tip prevents the wall of the organ from becoming caught or pinched during manipulation of the diagnostic or therapeutic instrument.

    摘要: The attenuation or isolation of environmental parameters on a gastric lumen is described herein. Once tissue plications are formed into a gastric lumen or sleeve within a stomach, the newly formed lumen is subjected to a multitude of fluctuating stresses or pressure from food or fluids passing therethrough, from naturally-occurring contractions, and/or from changes in pH levels from caustic stomach acids and hormones. The tissue interface between these plications can be isolated from such environmental fluctuations, or the fluctuations can be attenuated, by a number of methods. One example is to place a gastric stent or sleeve within the newly formed lumen. Another example is to utilize multiple rows of anchors, clips, or sutures along the interface. Alternatively, bio-adhesives can be dispensed to buttress the tissue interface. In another variation, the tissue can be approximated in different configurations which effectively reduce or isolate the adhered tissue region.
