Dr. Keith Zacher is pleased to offer a new and advanced procedure for your patients with progressive GERD, the LINX® procedure. The LINX® system is a small implant comprised of interlinked titanium beads with magnetic cores. The magnetic attraction between the beads augments the existing esophageal sphincter’s barrier function to prevent reflux. The device preserves the native anatomy and allows for the patient’s own physiologic reflux, swallowing, belching, and vomiting. The device is implanted using a standard minimally invasive laparoscopic approach.

GERD affects about 1 in 5 adults, and about 40% of patients currently on GERD medication still have symptoms. We all know the most common symptom of GERD is heartburn. However, GERD can also produce a wide variety of other symptoms including;

The LINX Advantage

Stop Reflux At Its Source

Image showing acid reflux

Reflux is caused by a weak muscle called the lower esophageal sphincter (LES) that allows acid and bile to flow back from the stomach into the esophagus, creating pain and often causing damage to the lining of the esophagus.

LINX is a flexible ring of small magnets placed around the LES during a minimally invasive procedure. The strength of the magnets helps keep the weak LES closed to prevent reflux.

When you swallow, LINX opens temporarily to allow food and liquid to pass into the stomach.
