1. A method for treating obesity in a patient, said method comprising:
- introducing a gastric balloon structure comprising a scaffold and at least two inflatable space-filling compartments to the inside of the patient'"'"'s stomach;
expanding the scaffold to provide a fixed support geometry within the stomach; and
at least partly filling the at least two space-filling compartments of the balloon with a compressible and/or incompressible fluid such that the compartments are constrained by the scaffold after filling.

Abstract
A gastric balloon includes a scaffold structure, one or more internal inflatable compartments within the scaffold structure, and one or more inflatable bladders formed over the space-filling compartment. The gastric balloon may be deployed transesophageally using a gastroscope and is inflated in situ, preferably using a combination of liquid and gas inflation media.

20. A method for deploying a gastric balloon structure in a patient, said method comprising:
-
introducing the balloon structure to the patient'"'"'s stomach; filling a scaffold structure to provide a fixed support geometry; and separately filling a plurality of isolated chambers within the scaffold structure, wherein the chambers have individual volumes such that the collective volume of the chambers remaining inflated after the deflation of any single chamber is such that the balloon is prevented from passing through the pyloric valve. - View Dependent Claims (21, 22, 23, 24, 25)
