Claim:
A gastric band configured to extend from a top end of a stomach to a bottom end of the stomach adjacent an antrum of the stomach to divide the stomach into a food pouch and fundic region and to provide a passage between the food pouch and fundic region, the passage formed at the bottom end of the stomach adjacent the antrum of the stomach, the gastric band comprising: a compartment-forming section comprising a distal end of the gastric band configured to extend from the top end of the stomach towards the bottom end of the stomach, the compartment-forming section having a first arm extending a majority of a length of said gastric band and a second arm extending a majority of the length of the gastric band and spaced apart from the first arm by a first distance configured to form the food pouch and the fundic region; a passage-forming section comprising a proximal end of the gastric band, the passage-forming section configured to extend from the bottom end of the stomach adjacent the antrum of the stomach towards the top end of the stomach, the passage-forming section configured to be positioned at the bottom end of the stomach adjacent the antrum of the stomach and configured to form the passage between the food pouch and the fundic region, the passage-forming section having a first arm extending in a direction towards and substantially collinear with the compartment-forming section and a second arm extending in a direction towards and substantially collinear with the compartment-forming section and at least partially spaced apart at a first portion by a second distance, which is greater than the first distance; and a biasing section configured to bias at least the first and second arms of the compartment-forming section to form the food pouch and the fundic region, wherein the first and second arms of the passage-forming section are arcuate and continuous, the first arm of the passage-forming section is continuous with the first arm of the compartment-forming section, and the second arm of the passage-forming section is continuous with the second arm of the compartment-forming section.
