Devices and methods for retaining a gastro-esophageal implant

A method of treating a patient having an esophagus, a stomach, and a gastro-esophageal junction, the method comprising:

• forming a tissue plication on a wall of a gastrointestinal tract at or adjacent the gastro-esophageal junction, the tissue plication including a width in a direction transverse to a flow of food from the esophagus into the stomach;
• and
• coupling a restrictor member to the tissue plication, the restrictor member being configured to restrict the flow of food from the esophagus into the stomach, wherein a width of the restrictor member is greater than the width of the tissue plication.

A method of treating a patient having an esophagus, a stomach, and a gastro-esophageal junction, the method comprising:

• attaching a plurality of discrete restrictor members to a wall of a gastrointestinal tract at or adjacent the gastro-esophageal junction, the plurality of restrictor members collectively being configured to restrict a flow of food from the esophagus into the stomach, the plurality of restrictor members being coupled to the gastrointestinal tract such that an opening between the discrete restrictor members directs the flow of food from the esophagus into the stomach, wherein a size of one or more of the restrictor members controls a size of the opening.
