For more than 10 years, Lenzing PROFILEN® PTFE yarns have been used by leading manufacturers of artificial heart valves to produce their challenging products. Our quality was initially demonstrated primarily in conventional surgical heart valves. In recent years, however, our yarn has also been used in minimally invasive TAVR (Transcatheter Aortic Valve Replacement) products. Last but not least, it is also used in some TMVR (Transcatheter Mitral Valve Repair) products that are now coming onto the market as critical supplier products. We would love to work with you on new developments as well!
