The LINX® System is a medical device which is placed around the Lower Oesophageal Sphincter (LOS) using a simple technique called laparoscopy (keyhole surgery). The device consists of a small flexible band of interlinked titanium beads with magnetic cores and is placed around the LOS in the closed position. The beads will separate temporarily as the force of a swallow allows food and drink to pass into the stomach. The magnetic attraction between the beads then brings the device back to the closed position to prevent reflux occurring. The magnets are calibrated to allow higher gastric pressures to open the device, but will not open for the lower gastric pressure of reflux. This means that the device will also open if there is a need to release increased pressure in the stomach (for example when belching or vomiting).
The LINX® System is made with neodymium permanent rare earth magnets. The magnets are cased in titanium and each bead is joined by individual titanium wires. The Roman arch design means that the device does not compress the tissue around the oesophagus and a specially designed clasp securely locks one end of the device to the other so it will not come undone. The device is positioned so it will not move from its location inside the body.
- acid heartburn
- a small hiatus hernia (or no hiatus hernia)
Preoperative investigations include gastroscopy, barium swallow (xray) and acid monitoring studies
The procedure can be carried out through keyhole surgery and takes approximately 90 minutes.
