The pyloric valve includes a blocking portion having a plurality of disc-shaped flanges connected in series. The blocking portion may be disposed in a contracted position wherein the plurality of disc-shaped flanges is disposed in a stacked configuration and a resting position wherein the plurality of disc-shaped flanges is disposed in a linear configuration. The pyloric valve may further include a sleeve that may have a beveled distal end. The pyloric valve may be constructed of silicon.
