摘要： A pyloric valve is provided for inhibiting the flow of chyme through the pyloric region of the gastrointestinal tract. 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. Also provided are methods of inserting and removing the pyloric valve, which each include a step of manipulating the support between its resting and contracted positions. Insertion and removal systems are also provided for use with the pyloric valve.

摘要： A pyloric valve is provided for inhibiting the flow of chyme through the pyloric region of the gastrointestinal tract. The pyloric valve includes a blocking portion having at least one axially-aligned annular flange defining a central opening and a support having a rim and a support surface. The support may be disposed in a nested position wherein the support surface is disposed within the central opening and an inverted position wherein the support surface is disposed away from the central opening. The pyloric valve may further include a sleeve that may have a beveled distal end. The pyloric valve may be constructed of silicon. Also provided are methods of inserting and removing the pyloric valve, which each include a step of manipulating the support between its inverted and nested positions. Insertion and removal systems are also provided for use with the pyloric valve.

摘要： A pyloric valve is provided for inhibiting the flow of chyme through the pyloric region of the gastrointestinal tract. The pyloric valve includes a blocking portion having a disc-shaped inlet and a helical flange. The helical flange may be disposed in a contracted position defining a contracted length and a contracted diameter and an extended position defining an extended length and an extended diameter, wherein the extended length is longer than the contracted length and the extended diameter is smaller than the contracted diameter. The pyloric valve may further include a sleeve that may have a beveled distal end. The pyloric valve may be constructed of silicon. Also provided are methods of inserting and removing the pyloric valve, which each include a step of manipulating the support between its contracted and extended positions. Insertion and removal systems are also provided for use with the pyloric valve.
