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

1. A method of inducing weight loss in a patient having an esophagus, a stomach, and an intestine, the method comprising the steps of:

passing in a distal direction a pouch implant having a proximal opening and a distal opening through the esophagus and into the stomach;

coupling the pouch implant to tissue at the gastro-esophageal junction of the stomach;

passing in a distal direction a sleeve implant comprising an elongate sleeve having an upstream opening, a downstream opening, and a lumen extending therethrough, such that the upstream opening of the sleeve implant is aligned with the distal opening of the pouch implant;

coupling the sleeve implant to the pouch implant; and

positioning the downstream opening of the sleeve implant within the intestine, such that food ingested by the patient passes from the esophagus directly through the pouch implant to the sleeve implant, and flows from the sleeve implant into the intestine.

2. The method of claim 1, wherein the method includes coupling the sleeve implant to the pouch implant before coupling the pouch implant to tissue at the gastro-esophageal junction of the stomach.

3. The method of claim 1, wherein the method includes coupling the sleeve implant to the pouch implant after coupling the pouch implant to tissue at the gastro-esophageal junction of the stomach.

4. The method of claim 1, wherein the pouch implant is proportioned to restrict the rate at which food flows from the esophagus into the upstream opening of the sleeve implant.

5. The method of claim 1, wherein the sleeve implant comprises a tapered tubular implant.

6. The method of claim 1, wherein the sleeve comprises a polymeric material.
