Abstract

The invention provides a plurality of devices for reducing the channel size, and the channel is a gastrointestinal tract in an example embodiment and so on. The device generally includes a cylindrical component as a limited element, which is provided with a proximal end and a distal end, at least one of the proximal end and the distal end can be connected on the wall of the gastrointestinal tract, thereby reducing the channel size. When in use, the limited element is provided with a structure which can be chosen at a first instant stop position and a second instant start position, and the diameter of the limited element at the start position is larger than the diameter at the stop position, so as to control the channel size. The invention further provides a method of using the device for appetite suppression.

Description

technical field [0001] The present invention relates to devices and methods for bariatric surgery, and in particular, to built-in gastric restriction devices and methods. Background technique [0002] One of the approaches to treating morbid obesity is bariatric surgery, which involves modifying the patient's digestive tract to promote weight loss and help maintain normal weight. A common bariatric surgical procedure is gastric bypass, which aims to reduce the volume of a patient's stomach by dividing the stomach into upper and lower pouches using staples and / or sutures. The jejunum (the middle part of the small intestine) is also divided into two parts. A portion of the jejunum (called the "loop of Roux jejunum") lies behind the colon and the lower gastric pouch and joins or "anastomoses" with the upper gastric pouch. The remaining end of the jejunum is attached to one side of the Roux jejunum loop. A new digestive pathway is thus created by which food passes through the...
