    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 alternative, a length of the Roux limb can be shortened endoluminally to create a malabsorptive region.

    摘要： An endoscopic tissue anchor deployment device includes a handle, an elongated shaft defining an internal lumen, and an end effector attached to the distal end of the elongated shaft. A tissue anchor catheter is removably inserted through the lumen of the elongated shaft, the catheter having a tissue anchor assembly that is deployable from its distal end. The handle may include a pin and track assembly that define a series of handle actuation steps corresponding to deployment steps for the deployment device end effector and the tissue anchor catheter. In some embodiments, the handle includes a catheter stop member that prevents movement of the tissue anchor catheter under certain circumstances, and a handle stop member that prevents actuation of the handle under certain circumstances.

    摘要： Apparatus & methods for endoscopic suturing are described herein. A distal tip of the endoscopic device engages the tissue and then approximates the engaged tissue to form a tissue fold. A needle body positioned within a flexible catheter is deployed into or through the newly created tissue fold where it is then detached or released from the endoscopic device. The needle body has a length of suture which depends therefrom and can be used to secure the tissue fold. The entire endoscopic device or its tissue engaging assembly can then be rotated relative to the tissue fold while maintaining engagement with the tissue to maneuver the flexible catheter to the opposing side of the penetrated tissue fold. This procedure can be repeated any number of times to create an interrupted, continuous, or running suture to secure the tissue fold.
