Redefining Cardiovascular Replacement

Xeltis is a clinical-stage medical device company pioneering a restorative approach in cardiovascular therapy.

RestoreX™, Xeltis technology platform, is the world’s first polymer-based technology designed to enable natural restoration of cardiovascular function, through a therapeutic approach called Endogenous Tissue Restoration (ETR).

Potentially addressing

millions of patients / year

Xeltis is currently investigating applications of its innovative approach to restore heart valves and small diameter blood vessels.

Over 25 patients implanted

  • Restorative small diameter vascular applications, including Coronary Artery Bypass Grafts (CABG) are showing promising results in preclinical trials.

  • The first few patients receiving Xeltis pediatric vascular grafts have now reached their 5-year follow-up.

  • Xeltis restorative heart valves have been in trials for years, including two clinical trials in EU, Asia and in the USA.
