Intragastric stent for duodenum bypass
First Claim
1. An intragastric stent comprising a substantially cylindrical thin-walled shell sized for snug fitting in a duodenum, the shell having a weave of flexible, resilient filaments and including an elastic peripheral membrane impervious to digestive juices such that, when deployed in the duodenum, uptake of food through the stent is lessened or inhibited.

Abstract
A porous weave of bioabsorbable filaments is encased in an elastic membrane to form a thin-walled stent. The stent is sized to be snugly fitted in the proximate portion of the duodenum of a patient, to induce weight loss by limiting uptake of food passing through the stent. After a predetermined period, the stent degrades and passes from the body without surgical intervention.

- 6. A method of inducing weight loss in a patient which comprises securing in the proximate portion of the duodenum of the patient a substantially cylindrical, thin-walled, flexible elastic stent impervious to digestive juices in the duodenum to limit uptake of food through the stent and along the portion of the duodenum in which the stent is fitted.
