Patent Images
1. A transoral gastroesophageal flap valve restoration device comprising:
- a first member; and
a second member hingedly coupled to the first member, the first and second members being arranged for esophageal passage into a stomach to receive stomach tissue there between to form a flap of a gastroesophageal flap valve, the first and second members being configured to flek in a direction to follow an esophageal path into the stomach and to be substantially rigid when receiving the stomach tissue there between and forming the flap of the gastroesophageal flap valve.

43. A method of restoring a gastroesophageal flap valve comprising:
-
providing a transoral gastroesophageal flap valve restoration device comprising a first member and a second member hingedly coupled to the first member, the first and second members being flexible for esophageal passage into a stomach and substantially rigid to receive stomach tissue there between to form a flap of a gastroesophageal flap valve when in a second orientation;
feeding the device down the esophagus into the stomach with the device in a flexible condition, rendering the device substantially rigid; and
pulling stomach tissue between the first and second members to form the flap of the gastroesophageal flap valve.

44. A method of restoring a gastroesophageal flap valve comprising:
-
providing a transoral gastroesophageal flap valve restoration device arranged for esophageal passage into a stomach when in a substantially flexible condition and to receive stomach tissue to form a flap of a gastroesophageal flap valve when in a substantially rigid condition;
feeding the device down the esophagus into the stomach with the device in the substantially flexible condition;
rendering the device into the substantially rigid condition; and
pulling stomach tissue into the device to form the flap of the gastroesophageal flap valve.
