Abstract

Devices and methods for gastrointestinal bypass are described. A gastrointestinal bypass device includes a gastrointestinal cuff and a gastrointestinal sleeve. The cuff may be configured to be attached in the esophagus, and may be sufficiently flexible to expand and collapse to conform with the inside of the esophagus to allow the esophagus to function substantially normally. The sleeve is configured to be coupled to the cuff, and may be made of a material that is floppy or flaccid but does not substantially expand radially.

Claims

1. A gastrointestinal cuff device configured to be attached in a gastrointestinal lumen, the device comprising:

a liner having a proximal portion and a distal portion, the liner configured to open and close with the gastrointestinal lumen;

a plurality of struts coupled to the liner; and

a scaffold coupled to the liner, the scaffold having a plurality of proximal segments and distal segments coupled by connecting segments, the distal segments of the scaffold positioned so as to cross the struts, the scaffold configured to provide an outward bias to increase conformance of the liner to an inside surface of the gastrointestinal lumen.

2. The device of claim 1, wherein the scaffold is shaped like a wave.

3. The device of claim 1, wherein the scaffold is shaped like a sawtooth wave.

4. The device of claim 1, wherein the scaffold is shaped like a sine wave.

5. The device of claim 1, wherein the scaffold is a mesh.

6. The device of claim 1, wherein the scaffold is coupled to an inner surface of the liner.

7. The device of claim 1, wherein the liner includes an inner layer and an outer layer, and wherein the scaffold is coupled to the liner between the inner layer and the outer layer.

8. The device of claim 1, wherein one or more of the struts are formed as a single piece with the scaffold.

9. The device of claim 1, wherein the scaffold is configured to rotate the struts when the liner closes.

10. The device of claim 1, wherein one or more of the struts includes a notch configured to be coupled to the scaffold.
