Abstract
An assembly including a bougie and a sheath for use in performing a gastroplasty for dividing a stomach of a patient into a sleeve receiving food and a bypass portion. The bougie includes an elongated body having a segment being shaped to follow a lesser curve of the stomach, and an extension member being movable within the stomach for positioning a distal portion thereof away from a gastroesophageal junction of the stomach and to define a fluid passage between the sleeve and the bypass portion. The sheath has an elongated main lumen in which the bougie is inserted and the sheath is translatable along the bougie to selectively expose the extension member of the bougie to perform its guiding action, or hide the extension member to ensure secure displacement of the bougie within the stomach and along the oesophagus.
