The LINX® device is a thin, bracelet of magnets that is surgically placed around the lower esophageal sphincter to control reflux. The magnets are encapsulated in titanium beads and connected to one another by titanium wires. The LINX® surgery is an outpatient surgical procedure performed using minimally invasive surgical methods either robotically or laparoscopically. During this procedure, the hiatus, stomach and esophagus are carefully assessed. If there is a hiatal hernia a hiatal hernia repair is performed. Then the diameter of the esophagus is measured and an appropriate size LINX® device is selected based on this measurement. The band of magnets is wrapped around the lower esophageal sphincter and fastened together with a proprietary clasping system.
The LES function is benefitted from the device’s increased opening pressure after it has been successfully implanted allowing passage of food down all the while making it more difficult to reflux. When the patient swallows, the lower esophagus will push the food causing the magnets to open, allowing the food to travel into the stomach. After the patient has finished swallowing, the magnetic attraction between the beads will assist the LES in contracting once more. When the LINX® device is closed and in its resting state, it increases the opening pressure of the lower esophageal sphincter thereby decreasing reflux episodes.
