How Does The LINX® System prevent Reflux?
The lower esophageal sphincter (LES) is the valve that prevents stomach contents from flowing backwards into the esophagus. Acid reflux sufferers have a weakened LES. This means bile and stomach acid can flow backwards into the esophagus causing pain and many other symptoms.
The LINX® System works to stop acid reflux through its unique proprietary technology: a flexible band of magnets encased in titanium beads, then strung together on titanium wire. The LINX System works with the patient’s own body to prevent GERD by keeping the LES closed when it should be closed and allowing it to open when needed.
LINX® System Animation
The attraction between the magnetic beads keeps the weakened lower esophageal sphincter (LES) closed most of the time, preventing the backwards flow of acid into the esophagus. When a LINX patient eats or drinks, the force exerted by the patient’s swallowing reflex temporarily breaks the magnetic bond. (See Figure 1.) This allows food and drink to enter the stomach. After swallowing, magnetic attraction re-closes the LES (Figure 2) and holds it closed, preventing reflux.

The LINX System Procedure
Your surgeon will put the LINX System in place via laparoscopy, a minimally invasive surgical technique. The procedure is done with general anesthesia and usually takes less than one hour. Once in place, the LINX System begins working right away. Patients who have the LINX procedure are able to eat and drink the same day and return to normal activities within a couple of days. As always, patients should consult their surgeon for their own post-op instructions.
