The LINX™ System is a series of miniature magnetic beads, linked together to form a “bracelet”. It works to prevent gastric reflux by augmenting the Lower Oesophageal Sphincter (LOS), the body’s natural anti-reflux barrier.
The LINX™ System is a small flexible band of interlinked titanium beads with magnetic cores. The magnetic attraction between the beads helps the LOS resist opening to gastric pressures, preventing reflux from the stomach into the oesophagus. Swallowing forces temporarily break the magnetic bond, allowing food and liquid to pass normally into the stomach. Magnetic attraction closes the LOS immediately after swallowing, restoring the body’s natural barrier to reflux.
The LINX™ Reflux Surgery Procedure The LINX™ procedure is performed by minimally invasive laparoscopic (keyhole) surgery and takes less than an hour. The device is placed around the oesophagus, just above the stomach, in the area of the Lower Oesophageal Sphincter. Once in place, the LINX™ System works immediately.
One key advantage of the procedure is that there is no anatomical alteration to the stomach, the device is designed simply to reinforce the body’s natural function. This means that if ever necessary, the procedure is totally reversible. Following the procedure, under physician guidance, patients should be able to resume a normal diet immediately and will typically resume normal activities in less than a week.
