LINX Reflux Management System
The LINX Reflux Management System is a flexible ring of small magnets placed around the esophagus just above the stomach during a minimally invasive procedure to help prevent reflux. LINX is intended for patients diagnosed with Gastroesophageal Reflux Disease (GERD) as defined by abnormal pH testing, and who continue to have chronic GERD symptoms despite maximum medical therapy.
How LINX Works
Reflux occurs when a muscle called the lower esophageal sphincter (LES) is weak or relaxing inappropriately. This allows acid and bile to flow from the stomach into the esophagus. The magnets in LINX help to keep the LES closed so that acid and bile do not flow from the stomach to the esophagus. When you eat or drink, the forces from swallowing cause the magnets to separate, the LINX device to expand, and the LES to open for food or liquid to pass into the stomach.
Control reflux, long term1*
85% of patients were free from dependence on daily reflux medication after treatment with LINX.1†
Durable resolution of bothersome heartburn.
88% of patients reported being free of heartburn five years after treatment with LINX.1‡
Durable resolution of moderate to severe regurgitation.
LINX eliminated moderate to severe regurgitation in 98% of patients.1§
Significant decrease in gassiness and bloating.

An alternative treatment to consider
Simply designed to be simple.
The LINX Reflux Management System is a reversible surgical solution where a ring of tiny magnetic beads is placed around the junction of the stomach and the esophagus.
The system is strong enough to help keep stomach acid down and flexible enough to allow food to pass through.2
Learn about the LINX procedure.
The LINX procedure is generally completed in less than one hour.2-4€ Most patients have same-day surgery or go home within 24 hours.4\\ Patients treated with LINX can resume a regular diet.5,6¥
Life with LINX
An inside look.
Designed to last long term. LINX is constructed from materials commonly used in other medical implants7,8$ and is MRI conditional.7Ω You should discuss the MRI scanning options with your doctor prior to deciding on treatment with the LINX system.
RestoreII, don't reconstruct.
Unlike other surgical treatments for GERD**, LINX does not require changes to the stomach anatomy. 3,9†† If necessary, LINX can be removed using a minimally invasive procedure. LINX preserves future treatment options for patients.1
Retained ability to belch and vomit.1,10‡‡
LINX preserves physiological function to belch and vomit.1,10§§ The titanium beads open and close to let food down, and if it needs to come up, it can.
Additional Treatment Options for GERD
Diet modifications to reduce or eliminate spicy/acidic food, caffeine, chocolate, alcohol and tobacco. Lifestyle modification such as elevation of head of bed, no meals 2-3 hours before bed, and weight loss (in overweight patients).
The benefits of medication include reduced stomach acid production, reduced inflammation of the esophageal lining, and relief from heartburn symptoms. However, medication does not address the mechanical cause of reflux disease. Studies have shown that up to 40% of patients continue to have symptoms while on medication.11¶¶
Traditional Anti-Reflux Surgery: Fundoplication
Fundoplication surgery involves wrapping the upper part of the stomach around the outside of the esophagus at the lower esophageal sphincter to help prevent reflux. It has been shown to reduce symptoms of heartburn, reflux, and bloating, and may also end dependence on medication.10

$ The LINX Reflux Management System device consists of titanium beads with magnetic cores that are connected with independent titanium wires. Titanium is a material used in multiple orthopaedic, cardiac and dental applications.
Ω This device can be scanned safely under the following conditions: 1) 1.5-Tesla static magnetic field, 2) maximum spatial gradient field of 17.15 T/m, 3) maximum MR system reported, whole body averaged specific absorption rate (SAR) of 4.0 W/kg in First Level Controlled Operating Mode, and 4) the patient may feel pressure around the lower esophagus; should the patient experience pain, immediately discontinue the scan and remove the patient from the MR environment. Refer to IFU for warnings/MRI safety information.

LINX Reflux Management System Important Safety Information
The LINX Reflux Management System is indicated for patients diagnosed with pathologic Gastroesophageal Reflux Disease (GERD) as defined by abnormal pH testing, and who continue to have chronic GERD symptoms despite maximum medical therapy.
The LINX Reflux Management System is labeled for use by physicians only.
Contraindications: Do not implant the LINX Reflux Management System in patients with suspected or known allergies to titanium, stainless steel, nickel, or ferrous materials.
Warnings: The LINX device is considered MR Conditional in a magnetic resonance imaging (MRI) system up to either 0.7 Tesla (0.7T) or 1.5 Tesla (1.5T), depending on the LINX model implanted. Scanning under different conditions may result in serious injury to you and/or interfere with the magnetic strength and the function of the device. In the event alternative diagnostic procedures cannot be used and MRI is required, the LINX device can be safely removed utilizing a laparoscopic technique that does not compromise the option for traditional anti-reflux procedures.
Failure to secure the LINX device properly may result in its subsequent displacement and necessitate a second operation.
General Precautions: The LINX device is a long-term implant. Explant (removal) and replacement surgery may be indicated at any time. Management of adverse reactions may include removal and/or replacement.
The LINX device has not been evaluated in patients with a hiatal hernia larger than 3 cm. Use of LINX device in patients with a hiatal hernia larger than 3 cm should be considered on the basis of each patient’s medical history and severity of symptoms.
The safety and effectiveness of the LINX device has not been evaluated in patients with Barrett's esophagus or Grade C or D (LA classification) or Grade IV (Savary-Miller) esophagitis.
The safety and effectiveness of the LINX device has not been evaluated in patients with electrical implants such as pacemakers and defibrillators, or other metallic, abdominal implants.
The safety and effectiveness of the LINX device has not been evaluated in patients with major motility disorders.
The safety and effectiveness of the LINX Reflux Management System has not been established for the following conditions:
- Suspected or confirmed esophageal or gastric cancer
- Prior esophageal or gastric surgery or endoscopic intervention
- Distal esophageal motility less than 35 mmHg peristaltic amplitude on wet swallows or <70% (propulsive) peristaltic sequences or a known motility disorder such as achalasia, nutcracker esophagus, and diffuse esophageal spasm or hypertensive LES
