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.
Claims17
A gastrointestinal bypass device, comprising:
- a gastrointestinal cuff configured to be at least partially positioned in an esophagus;
- and
- a gastrointestinal sleeve coupled to the cuff, the sleeve configured to be at least partially positioned in a stomach and a small intestine;
- wherein the cuff and the sleeve are configured to allow a bypassed portion of food to be bypassed past the stomach and into the small intestine, and wherein the cuff and/or the sleeve are configured to allow a nonbypassed portion of food to pass into the stomach.
A method of providing adjustable gastric bypass, the method comprising:
- positioning at least a portion of a gastrointestinal cuff in an esophagus;
- positioning at least a portion of a gastrointestinal sleeve in a stomach and a small intestine, wherein the cuff and the sleeve are configured to allow a bypassed portion of food to be bypassed past the stomach and into the small intestine, and wherein the cuff and/or the sleeve are configured to allow a nonbypassed portion of food to pass into the stomach;
- and
- adjusting an amount of the nonbypassed portion of food allowed to pass into the stomach.
