Our Technology Historically, chordae replacement has been used with high reproducibility and excellent results for repairing leaflet prolaspe but has required open-heart surgery with bypass to stop the heart while the repair is performed. The NeoChord DS1000 is a disposable device that is intended to replace damaged chordae by delivering artifical chordae tendinae or "neochords" in a beating heart using minimally invasive techniques. In patients with severe degenerative mitral valve regurgitation, early surgery is recommended for patients with no symptoms because the probability of surgical success is high. Waiting until symptoms develop is associated with harmful changes in the heart’s structure and function that may increase the potential for surgical complications. However, patients with no symptoms might be reluctant to undergo open-heart surgery with bypass. The NeoChord DS1000 may offer patients a less invasive procedure choice.
