Methods and apparatus for revision of obesity procedures
First Claim
1. A method for correcting a failed surgically-created pouch within a patient body, comprising:
- advancing a tissue manipulation assembly endoluminally into the failed surgically-created pouch;
evacuating fluid from the pouch to facilitate acquisition of tissue by the tissue manipulation assembly;
deploying at least one tissue anchor into a region of tissue around an opening between the pouch and a length of anastomosed intestinal tissue via the tissue manipulation assembly; and
approximating the at least one tissue anchor such that the opening between the pouch and the intestinal tissue is reduced in size.

Abstract
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.
