Abstract

A device for inducing weight loss in a patient includes a tubular prosthesis self-expandable from a collapsed position in which the prosthesis has a first diameter to an expanded position in which the prosthesis has a second, larger, diameter. In a method for inducing weight loss, the prosthesis is placed in the collapsed position and inserted into a stomach of a patient. The prosthesis is allowed to self-expand from the collapsed position to the expanded position and into contact with the walls of the stomach, where it induces feelings of satiety and/or inhibits modulation of satiety-controlling factors such as Ghrelin.

Claims11

Dependent claims

A method of implanting a device in a patient having an esophagus, a stomach, a gastro-esophageal junction, and an intestine, the method comprising the steps of:

passing in a distal direction a gastro-esophageal implant of the device through the esophagus, wherein the gastro-esophageal implant comprises an upstream opening, a downstream opening, and a lumen extending therethrough;
positioning the gastro-esophageal implant proximate the gastro-esophageal junction;
coupling the upstream opening of the gastro-esophageal implant within the gastro-esophageal junction;
passing in a distal direction a gastric bypass sleeve through the esophagus and into the stomach, wherein the gastric bypass sleeve comprises an upstream opening, a downstream opening, and a lumen extending therethrough;
positioning the upstream opening of the bypass sleeve proximate the gastro-esophageal junction;
and
positioning the downstream opening of the gastric bypass sleeve in the intestine,
wherein food ingested by the patient is configured to pass from the esophagus into the gastro-esophageal implant, and is configured to flow from the gastro-esophageal implant through the gastric bypass sleeve and directly into the intestine.
