1. A gastric space occupier, comprising:
- a tubular balloon having a tubular wall comprising an outer tubular layer and an inner layer tubular disposed within the outer tubular layer, the inner and outer tubular layers having a space therebetween, the wall defining an elongate lumen extending through the balloon; and
a fluid in the space between the inner and outer tubular layers.

Abstract
Systems for controlling obesity utilize a number of space occupiers positioned in the stomach to reduce the effective volume of the stomach. Such arrangements provides sufficient stomach volume consumption to induce weight loss, but enable use of space occupiers that are proportioned to minimize the threat of obstruction even if they should migrate into the intestine. In general, numerous small volume space occupiers are placed in the stomach such that the total volume equals or exceeds the single volume of prior art single unit space occupiers. However, each individual space occupier is proportioned so that it will pass without obstruction if it moves into the intestine.

8. A method of treating obesity in a patient, comprising:
-
placing a tubular balloon into a stomach, the tubular balloon including a tubular wall comprising an outer tubular layer and an inner layer tubular disposed within the outer tubular layer, and a space between the inner and outer tubular layers; filling the space between the inner and outer tubular layers with a fluid such that the fluid is contained within the tubular wall. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A gastric space occupier system comprising:
-
an elongate member having first and second end portions, the elongate member movable between a first generally streamlined position in which the elongate member is shaped for passage through the esophagus into the stomach, and a second position in which the elongate member is incapable of passage from the stomach into the intestine; and a fastener positioned to couple the first and second end portions together to retain the elongate member in the second position. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 25, 26)

24. A method of treating obesity in a patient, comprising:
-
introducing an elongate member in a streamlined first position through an esophagus into a stomach; moving first and second end portions of the elongate member relatively towards one another to position the elongate member in a second position in which the elongate member is incapable of passage from the stomach into the intestine; and coupling the first and second end portions together to retain the elongate member in the second position.

27. A method of treating obesity in a patient using a gastric implant, comprising:
introducing a plurality of gastric balloons within the stomach, each gastric balloon having a volume in the range of approximately 50-200 cc, wherein the plurality of gastric balloons reduce the effective volume of the stomach by an amount sufficient to cause the patient to lose weight. - View Dependent Claims (28, 29, 30, 31)
