Question: Describe the mechanism of action of the LINX system for treatment of gastroesophageal reflux disease.

Context: Magnetic sphincter augmentation with the LINX device for gastroesophageal reflux disease after U.S. Food and Drug Administration approval.
Magnetic sphincter augmentation (MSA) of the gastroesophageal junction with the LINX Reflux Management System is an alternative to fundoplication for gastroesophageal reflux disease (GERD) that was approved by the U.S. Food and Drug Administration (FDA) in March 2012.
Is the LINX reflux management system an effective treatment for gastro-oesophageal reflux disease?
BACKGROUND: Laparoscopic magnetic sphincter augmentation (MSA) with the LINX device is a promising new therapy for the treatment of gastroesophageal reflux disease (GERD).
Other nonmedical therapies include, the Stretta procedure, transoral incisionless fundoplication, and the magnetic sphincter augmentation device (LINX).
LINX(®) Reflux Management System in chronic gastroesophageal reflux: a novel effective technology for restoring the natural barrier to reflux.
The LINX(®) Reflux Management System (Torax Medical, St. Paul, MN, USA) is designed to provide a permanent solution to GERD by augmenting the sphincter barrier with a standardized, reproducible laparoscopic procedure that does not alter gastric anatomy and is easily reversible.
LINX(™) Reflux Management System: magnetic sphincter augmentation in the treatment of gastroesophageal reflux disease.
The LINX(™) Reflux Management System (Torax Medical) is designed to provide a permanent solution to GERD by augmenting the physiologic function of the sphincter barrier with a simple and reproducible laparoscopic procedure that does not alter gastric anatomy and can be easily reversed if necessary.
The Linx sphincter augmentation device has been developed to address this gap with improvement of the barrier function of LES and reversible design if necessary.
METHODS: A sphincter augmentation device (LINX Reflux Management System; Torax Medical, Shoreview, MN), designed to prevent reflux due to abnormal opening of the lower esophageal sphincter (LES), was laparoscopically implanted at the gastroesophageal junction in 44 patients.
Specific topics include reviews of long-term outcomes after laparoscopic antireflux surgery, the use of surgically placed implantable device for LES augmentation (Linx), the use of mesh for hiatal hernioplasty, and prone and nonthoracic approaches to minimally invasive esophagectomy.
LINX( ) Reflux Management System: magnetic sphincter augmentation in the treatment of gastroesophageal reflux disease.
METHODS: A sphincter augmentation device (LINX Reflux Management System; Torax Medical, Shoreview, MN), designed to prevent reflux due to abnormal opening of the lower esophageal sphincter (LES), was laparoscopically implanted at the gastroesophageal junction in 44 patients.
BACKGROUND: Sphincter augmentation with the LINX� Reflux Management System is a surgical option for patients with chronic gastroesophageal disease (GERD) and an inadequate response to proton pump inhibitors (PPIs).
A sphincter augmentation device (LINX Reflux Management System; Torax Medical, Shoreview, MN), designed to prevent reflux due to abnormal opening of the lower esophageal sphincter (LES), was laparoscopically implanted at the gastroesophageal junction in 44 patients
Sphincter augmentation with the LINX Reflux Management System provided long-term clinical benefits with no safety issues, as demonstrated by reduced esophageal acid exposure, improved GERD-related quality of life, and cessation of dependence on PPIs, with minimal side effects and no safety issues
The limitations of current therapy for GERD have encouraged a search for more effective treatment.The Linx sphincter augmentation device has been developed to address this gap with improvement of the barrier function of LES and reversible design if necessary.
LINX Reflux Management System is a sphincter augmentation device designed to prevent gastroesophageal reflux due to abnormal opening of the lower esophageal sphincter (LES) by augmenting the sphincter barrier. It is implanted via laparoscopic procedure that does not alter gastric anatomy and is easily reversible.
