Devices and methods for gastrointestinal bypass

摘要

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.

主权项

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.
