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.

Claims (18)

1. 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.

2. The method of claim 1 , wherein sutures couple the gastro-esophageal implant and the gastric bypass sleeve to each other.

3. The method of claim 1 , further comprising allowing at least a portion of the device to self-expand.

4. The method of claim 1 , wherein passing the gastro-esophageal implant and gastric bypass sleeve distally through the esophagus includes placing a sheath into the esophagus, wherein the gastro-esophageal implant and the gastric bypass sleeve are within the sheath.

5. The method of claim 1 , wherein a wall of the gastro-esophageal implant tapers inwardly from the upstream opening to the downstream opening.

6. The method of claim 1 , wherein the gastro-esophageal implant is self-expandable.

7. The method of claim 1 , further comprising introducing the gastro-esophageal implant into the esophagus in a collapsed position and allowing the gastro-esophageal implant to expand into contact with tissue proximate the gastro-esophageal junction.

8. The method of claim 1 , wherein the gastro-esophageal implant includes a plurality of struts extending in a proximal-distal direction.

9. The method of claim 1 , wherein coupling the gastro-esophageal implant within the gastro-esophageal junction includes suturing the gastro-esophageal implant to tissue.

10. The method of claim 1 , wherein the gastric bypass sleeve includes a polymeric material.

11. The method of claim 1 , further comprising coupling the downstream opening of the gastro-esophageal implant to the upstream opening of the gastric bypass sleeve.
