On-X® Life’s Chord-X™ Mitral Valve Chordal Repair System Launched at STS

It’s been the Society of Thoracic Surgeons Annual Meeting in San Diego for the last few days, an event that has seen On-X® Life Technologies Inc. unveiling its Chord-X™ Mitral Valve Chordal Repair System.


Mitral valve repair has hitherto been generally performed with the aid of an annuloplasty ring, and recent years have seen some surgeons use ePTFE sutures to create artificial chords, a subvalvular structure of the mitral valve, functionally reminiscent of the real thing.

The On-X LTI system aims to simplify the procedure, coming with its own ePTFE sutures and featuring:

  • Chord-X™ Chordal Sizer allowing accurate measurement of artificial chord length
  • Chord-X™ Pre-Measured Loops designed to save OR time and standardize artificial chord replacement
  • Chord-X™ Adjustable Suture System for surgeons who prefer to adjust and customize chordal loop length

The company held its own sponsored symposium on Sunday, January 25, 2015 featuring A. Marc Gillinov, MD, The Cleveland Clinic: “New Technology to Simplify Mitral Chordal Replacement” and James S. Gammie, MD, University of Maryland: “Chordal Replacement versus Resection.”

Company comments

On-X LTI’s CEO Clyde Baker stated, “We are pleased to provide surgeons with innovative tools designed to help make mitral valve chordal replacement more reproducible and save OR time. We are appreciative of the excellent team of surgeons who have helped design this product and for our excellent product development team which produced this innovation.”
