How Does the LINX® System Work?

Gastro-oesophageal Reflux Disease (GORD) is a chronic, often progressive disease resulting from a weak Lower Oesophageal Sphincter (LOS). The LINX® Reflux Management System augments the weak LOS, restoring the body’s natural barrier to reflux.

GORD results from a weak Lower Oesophageal Sphincter (LOS). The weak LOS allows acid and bile to reflux from the stomach into the oesophagus.

The LINX® System augments the LOS, restoring the body’s natural barrier to reflux.

How Does the LINX® System Work?

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 (See Fig. 1). Swallowing forces temporarily break the magnetic bond, allowing food and liquid to pass normally into the stomach (See Fig. 2). Magnetic attraction closes the LOS immediately after swallowing, restoring the body’s natural barrier to reflux (See Fig. 3).

How is the LINX® System Implanted?

The LINX® System is placed around the oesophagus just above the stomach using a common, minimally invasive surgical technique called laparoscopy. (See Fig. 1-3).

Patients are placed under general anesthesia during the procedure, which generally lasts less than an hour. Unlike other surgical treatments for GORD, the LINX® System does not require any anatomic alteration of the stomach. Most patients go home the day after surgery and resume a normal diet.

Frequently Asked Questions

Q. When can I start eating normally again?

Patients are encouraged to return to a normal diet as quickly as tolerated. This helps the body adapt to the LINX® Reflux Management System.

Q. When can I return to normal physical activities?

Generally, patients are able to return to non-strenuous activity within a couple of days, however, as with any surgical procedure, you should consult your physician regarding post-operative care.

Q. Can I go through airport security?

The LINX® Reflux Management System should not affect airport security, however, all patients will be provided with an implant card to have available in the event an issue arises.

Q. Can I have an MRI test after receiving the LINX® Reflux Management System?

If you are told you need an MRI procedure, please contact your LINX® physician. It is important to know which LINX® device you have. The LX models of LINX® are considered MR Conditional in a magnetic resonance imaging (MRI) system up to 0.7 Tesla. The LXM models of LINX® are considered MR Conditional in a MRI system up to 1.5 Tesla.  Scanning under different conditions may interfere with the magnetic strength and function of the device. LINX® implants PRIOR to September 10, 2015 have the LX model. If your LINX® implant was AFTER September 10, 2015, contact your LINX® physician.

Q. Will the magnets wear out?

The LINX® Reflux Management System uses permanent magnets that are designed never to wear out.
