Revolutionary Approach

Xeltis is revolutionizing the treatment of heart valve disease. In a process called Endogenous Tissue Restoration (ETR), the patient’s natural healing system develops tissue that pervades Xeltis’ implant, forming a new, natural and fully functional heart valve. As ETR occurs, Xeltis’ heart valves are gradually absorbed by the body.

Xeltis is leveraging breakthrough science to transform heart valve treatment – making the seemingly impossible, possible.

Xeltis’ heart valves have a porous structure made of polymers, based on Nobel-prize awarded science.

The latest generation of supramolecular polymers are strong and flexible enough to meet the requirements of a beating heart.

Xeltis’ history is the culmination of substantial developments in regenerative medicine, supramolecular chemistry and electrospinning.

2011:

Xeltis and QTIS merge, abandon tissue engineering to focus on ETR and to develop the RestoreX technology platform.

2013:

First patients implanted with Xeltis bioabsorbable blood vessels (pulmonary conduit) and patches.

2016:

First patient implanted with Xeltis bioabsorbable pulmonary heart valve in clinical trials, with Thierry Carrel as Principal Investigator.
