A gastric band assembly has one or more bladders incorporated therein to minimize or modulate changes in intra-band pressure in response to changes in stoma area and band stoma area. The balloon portion of the gastric band encircles stomach tissue thereby forming a band stoma area. With the bladders incorporated in the gastric band assembly, the affect that changes in band stoma area have on intra-band pressure are minimized so that the patient stays at or near the physician set intra-band pressure longer than with a gastric band alone.
