A gastric band has a balloon shaped and dimensioned to circumscribe the stomach at a predetermined location and a belt extending about the balloon. Further, a linking layer is positioned between the balloon and the belt, wherein the linking layer is harder than either the balloon or the belt. Additionally, the belt includes a first latching member at a first end of the gastric band and second latching member at a second end of the gastric band, the first latching member and the second latching member being shaped and dimensioned for selective engagement to secure the gastric band about a stomach of a patient, wherein the first latching member and second latching member are composed of different materials.
