1. A method of treating obesity in a patient, said method comprising:
- passing an intra-gastric sizing device trans-orally into the patient and into the cavity of the stomach of the patient;
pushing on the outer wall surface of the stomach with an instrument to deform the stomach wall inwardly, so that portions of the outer surface of the stomach wall fold inwardly upon one another, wherein the stomach wall is deformed by said pushing until contacting the intra-gastric sizing device;
fixing the outer wall portions together to maintain an orientation wherein the folded wall portions face toward one another;
expanding an expandable member to expand against the folded wall portions; and
removing the instrument, while leaving the expanded expandable member in place.

2. A method of treating obesity in a patient, said method comprising:
-
passing an intra-gastric sizing device trans-orally into the patient and into the cavity of the stomach; pushing on the outer wall surface of the stomach with an instrument to deform the stomach wall inwardly, so that portions of the outer surface of the stomach wall fold inwardly upon one another, wherein the stomach wall is deformed by said pushing until a signal from said intra-gastric device indicates that sufficient deformation has been accomplished; fixing the outer wall portions together to maintain an orientation wherein the folded wall portions face toward one another; expanding an expandable member to expand against the folded wall portions; and removing the instrument, while leaving the expanded expandable member in place.

3. A method of treating obesity in a patient, said method comprising:
-
passing an intra-gastric sizing device trans-orally into the patient and into the cavity of the stomach of the patient; pushing on the outer wall surface of the stomach with an instrument to deform the stomach wall inwardly, so that portions of the outer surface of the stomach wall fold inwardly upon one another; monitoring an amount of deformation of the stomach wall inwardly; ceasing further deformation inwardly by said pushing when a predetermined distance between the inner surface of the stomach wall and the sizing member has been achieved; and fixing the outer wall portions together to maintain an orientation wherein the folded wall portions face toward one another; expanding an expandable member to expand against the folded wall portions; and removing the instrument, while leaving the expanded expandable member in place.

4. A method of treating obesity in a patient, said method comprising:
-
pushing on the outer wall surface of the stomach with an instrument to deform the stomach wall inwardly, so that portions of the outer surface of the stomach wall fold inwardly upon one another; passing an intra-gastric sizing device trans-orally into the patient and into the cavity of the stomach, prior to said pushing, wherein the stomach wall is deformed by said pushing until contacting the intra-gastric sizing device; fixing the outer wall portions together to maintain an orientation wherein the folded wall portions face toward one another; expanding an expandable member mounted on a distal end portion of the instrument to expand against the folded wall portions; and removing the instrument, while leaving the expanded expandable member in place.
