Mayo Clinic-linked med device firm close to FDA OK

Here's a little from an interestng piece by Lindsay Patton on about Torax Medical's anti-acid reflux device.

Mayo Clinic helped launch Torax in 2003 and Mayo Medical Ventures has invested in the company in the past.

John Deedrick, a Rochester venture capitalist who previously worked with Mayo Clinic, is also on Torax's board of directors.


A FDA panel has given unanimous support to LINX, an implantable device to treat chronic and severe acid reflux. That means LINX is one step closer to being available for US patients.

TORAX_twitter_picThe LINX Reflux Management System is a flexible ring of titanium magnetic beads. It's implanted on the lower end of the esophagus to prevent stomach acid and food from rising.

The magnetic attraction between the beads work to resist the gastric pressure that causes acid reflux. But when people are eating, it allows food and liquids to pass into the stomach normally.

LINX is produced by Torax Medical, a medical device company based in Minnesota. The device has already been on the market in some European countries for two years.


LINX is not recommended for patients who need MRI scans, due to the magnetic nature of the beads.

Torax plans a follow-up study of 200 patients to test LINX's long-term safety and effectiveness.


What surgery is included by this implant and if you have this problem as I do, how can anyone know if they will need an MRI down the line? If an MRI is needed does the implant need to be removed?
