DEVICES AND SYSTEMS FOR GASTRIC VOLUME CONTROL
First Claim
1. A gastric balloon positionable within the gastric cavity above the pylorus, said balloon having a constrained configuration that can be introduced into the gastric cavity and a deployed configuration that assumes an overall space-filling geometry with a curved longitudinal axis to maintain the distended shape of the gastric cavity in the feeding state, said balloon comprising:
- two or more inflatable compartments held in place adjacent to each other and together defining the space-filling geometry of the balloon in the deployed configuration, anda valve structure coupled to one or more of said inflatable compartments, said valve structure allowing fluids to enter the compartment(s) and preventing said fluids from exiting such compartment(s); and
one or more filling tubes detachably coupled to one or more said valve structures through which fluids are delivered into the compartments from outside the body for deployment, andwherein each of said compartments has an individual volume such that, after the deflation of any single compartment, the collective volume and dimensions of the balloon including the remaining inflated compartments and the valve structures prevent the balloon from passing through the pylorus.

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.

16. A gastric balloon having a deployed configuration that is positionable in the stomach above the pylorus, said balloon comprising:
-
at least two compartments, each said compartment being at least partly filled with a compressible or incompressible fluid in the deployed configuration, and one or more markers disposed within at least two of the said compartments, wherein each of the said markers provides a detectable signal upon a compromise of structural integrity of the compartment, wherein in the event of a structural failure of a compartment with a marker, such a compartment breach can be detected and in the event of the structural failure of two or more compartments with different markers, more than one compartment breach can be detected. - View Dependent Claims (17, 18, 19, 20, 22, 23)

-
21. A gastric balloon as in claim 116, wherein the chemical markers are the same but different in composition or concentration.
-
24. A method to diagnose the integrity of a gastric balloon by examining at least two components of the balloon subject to structural failure, each marker being indicative of the nature, location, or extent of a failure, said method comprising:
-
providing a gastric balloon having one or more markers disposed within each of the said components, each of the said markers is capable of providing a detectable signal upon a breach of structural integrity of such component distinguishable from the signal of the marker disposed within another component, and detecting one or more signals as an indication of the failure, impending failure, or the extent of failure of the balloon. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33)
