Abstract

A satiation device is described which includes a sheath or liner extending from the proximal or middle stomach to the distal antrum. Food ingested by the patient passes through the sheath or liner, thereby minimizing contact between the ingested food and the stomach. It is believed that over time, reduced contact between food and the stomach will result in decreased Ghrelin production by the patient and a consequent decrease in appetite. In some embodiments, the satiation device may also include a proximal pouch and/or a distal bypass tube.

Claims15

Dependent claims

An implant for a patient having an esophagus, a gastro-esophageal junction region, and a small intestine, comprising:

a gastro-esophageal sleeve extending from an upstream end to a downstream end, the upstream end of the sleeve being configured to be attached to the gastro-esophageal junction region such that food from the esophagus enters the upstream end of the sleeve, wherein the upstream end of the gastro-esophageal sleeve comprises a gastro-esophageal junction tissue-contacting surface;
and
an intestinal tube having a proximal portion and a distal portion, wherein the proximal portion is fluidly coupled to the downstream end of the sleeve, wherein a space between a distal end of the proximal portion and a proximal end of the distal portion does not include a tube portion and is exposed to a portion of an intestinal wall,
wherein the gastro-esophageal sleeve is funnel-shaped, and
wherein the gastro-esophageal sleeve is self-biased towards an open arrangement.
