Magnetic Device Studied as Treatment for Acid Reflux

Medication offers short-term relief for some sufferers of GERD. A magnetic device, currently being evaluated at UC San Diego Medical Center, may provide a solution for those individuals who want another option beyond long-term use of medications.

The device, called the LINX Reflux Management System, is being studied at UC San Diego Medical Center as part of a US and European multicenter clinical trial. Santiago Horgan, MD, director of minimally invasive surgery at UC San Diego Medical Center, is the site’s principal investigator.

Dr Horgan states, “The goal of this clinical trial is to correct a defect in the lower esophagus so that the body can function naturally without pain or discomfort.”

During a 20-30 minute minimally-invasive surgical procedure, the device, made up of a series of magnetic beads, is secured around the bottom of the esophagus. Once in place, the magnetic attraction between the beads supports the valve to protect the esophagus from reflux, while still allowing it to open during swallowing or to release gas. Made of permanent rare earth magnets encased in titanium, the band is sized to fit each patient.

While medication can suppress the production of stomach acid, the structural problem that allows the reflux is still there. Dr Horgan states that the device can restore the body's physiological barrier, and thus correct the cause of reflux itself.

The current clinical trial is sponsored by the device's manufacturer, Torax Medical, Inc. of Shoreview, Minnesota. This clinical trial will evaluate the safety and effectiveness of the device in up to 100 patients.

If this clinical trial proves the LINX Reflux Management System is effective in the treatment of GERD, it could be a valuable treatment option for GERD patients.
