Gastro-esophageal implants

摘要

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.

主权项

1. 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 opening at an upstream end to a downstream opening at a downstream end, the sleeve being configured to be secured within the gastro-esophageal junction region such that the upstream opening is aligned with the esophagus; and an elongate tube coupled to the sleeve, the tube including an intestinal portion, and the tube being dimensioned such that the intestinal portion is configured to extend into the small intestine when the sleeve is secured within the gastro-esophageal junction region, wherein the upstream end of the sleeve includes a plurality of attachment points, and wherein the sleeve is configured to be secured within the gastro-esophageal junction region at the attachment points.
