FATIGUE-RESISTANT GASTRIC BANDING DEVICE
First Claim
1. A gastric band for the treatment of obesity suitable for laparoscopic placement around the stomach of a patient to create a stoma comprising:
- a body portion or encircling the stomach; and
a multi-chambered inflatable member substantially coextensive with said body portion of said gastric band when said band is place around the stomach, wherein said chambers eliminate creasing, folding or wrinkling along an inner stomach-facing surface of said inflatable member, thereby reducing fatigue on the inflatable member.

Abstract
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.
