Each of these are effective in the treatment of obesity, but carry inherent risks associated with surgery, stapling and transection of the stomach, and pain and potential infection(s) associated with post operative recovery due to the skin incisions.
Additionally, access to the patient's stomach is difficult in obese patients, further complicating the surgery.
The procedure itself is time consuming due to the difficult acce

A. Method of Stomach Volume Reduction

[0078]In accordance with one aspect, there is provided a method for treating an obesity-related eating disorder in a patient by creating, an elongate continuous tissue plication in the anterior wall, posterior wall, and / or fundus of a patient's stomach. The terms “tissue plication” and “tissue fold” are used interchangeably herein, and as applied to the present method, refer to a two-layer tissue fold within the stomach having an serosal surfaces in contact with one another.

[0079]The method preferably employs tissue-acquisition devices and methods which will be detailed below in Sections C-E. For purposes of this section, it is worth noting only that a device suitable for the method (i) can be placed within the stomach intraorally at the distal end of a flexible shaft also having user controls at its proximal end, (ii) includes tissue-acquisition structure for capturing and fastening a two-layer tissue plication within the stomach, and (iii) can ...

Abstract

Devices and methods for acquiring and fastening tissues folds within an internal organ, such as the stomach, and for applying the methods and devices to producing reductions in organ volume or repair of bariatric procedures, are disclosed. An exemplary method for forming a continuous laterally extending tissue fold involves forming a succession of laterally extending folds having adjacent overlapping fold portions. One exemplary tissue-acquisition device has an open-end roller-and-arm structure that allows individual tissue folds to be formed and fastened, then advanced to an adjacent region within the stomach, for capture of a new fold that will form an extension of the existing fold(s).

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to U.S. Provisional Application Ser. No. 61 / 347,345 filed May 21, 2010, which is herein incorporated by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to devices and methods for acquiring and fastening tissues folds within an internal organ, such as the stomach, and for applying the devices and methods to producing reductions in organ volume or repair of bariatric procedures.BACKGROUND OF THE INVENTION[0003]Numerous surgical procedures are performed to treat the chronic disease of obesity. Common surgical procedures include Roux en Y gastric bypass, Sleeve Gastrectomy, Gastric Banding and Biliopancreatic Diversion with or without duodenal switch. Each of these are effective in the treatment of obesity, but carry inherent risks associated with surgery, stapling and transection of the stomach, and pain and potential infection(s) associated with post operative recovery due ...
