The LINX Reflux Management System is a medical device for patients 21 years and older who have been diagnosed with Gastroesophageal Reflux Disease (GERD) and continue to have heartburn or regurgitation, despite taking medication to treat GERD.
GERD occurs when the sphincter (valve) between the stomach and esophagus is weak or opens abnormally. Stomach juices reflux into the esophagus and may injure the esophagus and cause symptoms of heartburn or regurgitation.
The LINX System is designed to help the sphincter stay closed to stop the reflux. It uses a small, flexible band of beads. Each bead has a magnet inside. When placed around the outside of the esophagus, the magnetic attraction between the beads helps the sphincter stay closed to prevent reflux. Swallowing food will overcome the magnetic attraction and allow the beads to separate, allowing food and liquid to pass normally into the stomach.
