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.

Claims23

Dependent claims

A method for treating obesity in a patient, comprising the steps of

providing a pouch having a proximal opening and a distal opening;
positioning the pouch within the stomach of a patient;
placing the proximal opening of the pouch in the region of the distal end of the esophagus and approximately aligning said proximal opening with said distal end;
securing the pouch within the stomach;
and
causing food ingested by the patient to flow from the esophagus into the pouch;
and
causing the pouch to restrict flow of food from the pouch into the stomach at a rate that is slower than a rate at which food would move from the esophagus to the stomach in the absence of the pouch.
