We are proud to offer cutting-edge and innovative therapies and treatments for a variety of conditions and diseases.
LINX Reflux System for GERD
The LINX® Reflux Management System is a laparoscopic, fundic-sparing anti-reflux procedure indicated for patients diagnosed with Gastroesophageal Reflux Disease (GERD).
The LINX system is a small flexible band of interlinked titanium beads with magnetic cores designed to restore the body’s natural barrier to reflux in patients with GERD. The LINX® Reflux Management System (LINX device) consists of a series of titanium beads, each with a magnetic core, connected together with titanium wires to form a ring shape. The LINX device is surgically implanted around the lower end of the esophagus. It is used to treat gastroesophageal reflux disease (GERD) in patients who continue to have GERD symptoms despite the use of medical therapy (acid pills such as proton pump inhibitor medications) for the treatment of their reflux.
What the LINX Is
How the LINX Works
Even though the LINX device helps to prevent stomach contents from flowing back into the esophagus, it does not prevent movement of food or liquids down the esophagus into the stomach. When the patient swallows, the pressure in the esophagus increases and the magnetic beads move apart on the titanium wires. As the beads move apart, the magnetic force decreases. This separation of the beads allows food or liquids to pass normally into the stomach. After the food or liquids have passed into the stomach, the magnetic beads return to the closed position.
Da Vinci Robotic Surgery
While Dr. Matthew Schultzel’s area of expertise is minimally invasive colorectal surgery, his passion for treating the whole patient is what sets him apart.
