The LINX System is a small band of linked titanium beads with magnetic cores that is surgically placed around the esophagus, above the stomach. This procedure is performed laparoscopically. The interlinked beads have a magnetic attraction, which causes the LES to resist opening to stomach pressures, preventing reflux from the stomach into the esophagus. With the LINX system in place, swallowing temporarily breaks the magnetic bond, allowing food and liquid to pass normally into the stomach. Immediately after swallowing, the LES closes, restoring the body's natural barrier to reflux.
