20080262294 | ENDOSCOPIC SYSTEM WITH DISPOSABLE SHEATH - An endoscopic system includes a sheath having a flexible sheath body. A tip is attached to a distal end of the sheath body. A handle is attached to the proximal end of the sheath body. A steerable section may be provided in the sheath adjacent to the tip. Steering controls may then be provided on the handle for steering the steerable section. Lumens extend from the tip to the handle. The distal end of each lumen is sealed to the tip. Bodily fluids can only enter into the lumens and not other areas within the sheath. A shapelock assembly has an elongated hollow body positionable within the sheath body. The shapelock body may be switched between generally rigid and flexible conditions. The sheath provides a sterile barrier around the shapelock body. The shapelock assembly can be readily reused and the sheath may be disposable. | 10-23-2008 |

20110098725 | DEVICES AND METHODS FOR ENDOLUMENAL WEIGHT LOSS TREATMENTS - Devices and methods for forming and securing tissue folds, elongated invaginations, and tissue appositions in stomach tissue are used as a treatment for obesity. In a first embodiment, a plurality of tissue folds is formed in the fundus region of the stomach. In a second embodiment, one or more elongated invaginations are formed in the body region and/or antrum of the stomach. In a third embodiment, a plurality of tissue folds is formed in the fundus region of the stomach and one or more elongated invaginations is formed in the body region and/or antrum of the stomach. In other embodiments, a plurality of tissue folds is formed in the fundus region of the stomach and one or more tissue appositions are formed in the body region and/or antrum of the stomach. Additional embodiments include various combinations of tissue folds, elongated invaginations, tissue appositions, and other reconfigurations of stomach tissue. | 04-28-2011 |
20110245846 | ENDOSCOPIC TISSUE ANCHOR DEPLOYMENT DEVICES AND METHODS - 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. In some embodiments, the handle includes a pin and track assembly that defines 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. | 10-06-2011 |
20110313247 | SYSTEM FOR TISSUE DISSECTION AND RETRACTION - A system for tissue dissection and retraction is disclosed herein. A tissue dissection assembly generally comprises an elongate body shaft, an actuation member movable relative to the elongate body shaft, and at least one dissector arm member having at least a first end attached to the elongate body shaft, wherein the at least one dissector arm member is adapted to reconfigure within a plane from a low profile to an expanded profile when urged via the actuation member, and wherein the at least one dissector arm is further adapted to dissect tissue within the plane. In use, the assembly dissects tissue within the plane typically by advancing the elongate body shaft into the tissue region where the dissector arm member or members are then reconfigured within the plane from its low profile to its expanded profile to thereby dissect the tissue region along the plane. | 12-22-2011 |
20120232568 | SURGICAL TREATMENT OF GASTRIC EMPTYING DISORDERS - Devices and methods for surgically altering stomach tissue to change gastric emptying. Plications are formed in the stomach speed up or slow down gastric emptying, depending on the number and locations of plications used. The plications may be formed endolumenally. | 09-13-2012 |
20130217957 | DEVICES AND METHODS FOR THE ENDOLUMENAL TREATMENT OF OBESITY - A surgical method for treating obesity by reducing the size and/or function of the stomach includes forming at least two plications or tissue folds in tissue of a patient using anchor assemblies having a loop. The plications are then optionally allowed to heal. A loop suture or wire is threaded through the loops. The loop suture is then tensioned to draw the plications towards each other. The loop suture is then secured via a knot or a cinch. When the method is performed in the stomach for treatment of obesity, forming the plications reduces the volume of the stomach. Drawing the plications together creates a contracted tissue area which further reduces the volume of the stomach. Additional plications may also be formed and drawn together with the same loop suture, or with a different loop suture. | 08-22-2013 |

In a third embodiment, a plurality of tissue folds is formed in the fundus region of the stomach and one or more elongated invaginations is formed in the body region and/or antrum of the stomach. In other embodiments, a plurality of tissue folds is formed in the fundus region of the stomach and one or more tissue appositions are formed in the body region and/or antrum of the stomach. Additional embodiments include various combinations of tissue folds, elongated invaginations, tissue appositions, and other reconfigurations of stomach tissue. | 05-08-2014 |
20140257351 | METHODS AND APPARATUS FOR REVISION OF OBESITY PROCEDURES - 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. | 09-11-2014 |
