A fatigue-resistant inflatable gastric banding device suitable for laparoscopic placement around the stomach of a patient for the treatment of obesity and a method for such treatment are disclosed. The device includes a gastric band having a chambered inflatable member, substantially coextensive with an inner stomach facing surface of the band, that does not crease, wrinkle or fold when adjusted, so as to present a substantially smooth contour along the inner circumference, and to avoid fatigue or failure of the member itself. A gastric band having multiple inflatable compartments or chambers, which may be inflated together or individually is also disclosed.
