摘要：
A method is used to reduce a volume of a stomach of a patient. The method includes inverting a portion of a stomach wall to thereby create an inverted portion. An expandable member is positioned adjacent to the outer surface of the inverted portion. The expandable member is expanded to thereby expand the inverted portion. The expanded expandable member has a first outer diameter. A base region of the inverted portion is cinched to thereby capture the expanded expandable member in the expanded inverted portion. The expanded expandable member has a first outer diameter. Expanding and cinching provide a cinch diameter to first outer diameter ratio from approximately 0.5:1 to approximately 0.9:1.
