Transformative vascular implants

Addressing major life-threatening diseases, backed by Nobel-winning science

TECHNOLOGY

Xeltis is developing artificial vessels and valves that are gradually replaced by patients’ own living healthy tissue.

The natural creation of living and long-lasting vessels reduces the risk of thrombosis, stenosis, calcification and infection which are often the root cause of failure.

These groundbreaking implants, based on our proprietary Endogenous Tissue Restoration (ETR) based platform, are transforming the treatment of major life-threatening diseases.
Xeltis’ ETR technology is driven by Nobel prize-winning breakthroughs in polymer technology.

APPLICATIONS

The ambition at Xeltis is to improve standards of care for millions of patients who undergo vascular surgery every year, including hemodialysis access and coronary arterial bypass surgery.

Other potential applications for our ETR platform, include pulmonary heart valves and other vascular indications such as peripheral arterial disease.

Xeltis aims to meet the needs of patients and healthcare providers by providing self-healing, non-immunogenic implants that remain open, with a low risk of infection and reduced need for surgical reintervention.
