Transformative vascular implants

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

aXess™

aXess is a medical device for patients requiring vascular access for hemodialysis. At implantation the patient’s own cells infiltrate the porous scaffold and begin early tissue integration. Post implantation aXess is ready for cannulation after 14 days. Over time, it transforms into each patient’s own living vessel for reliable vascular access.

ABOUT

Xeltis is an an international medtech company with business with roots in the Netherlands and commercial and clinical operations throughout Europe and the US. We are a passionate and driven team, with expertise from world-renowned universities and innovative life science companies, backed by high-quality advisors and investors.

About
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 reduce risk of:

  • Thrombosis
  • Infection
  • Reinterventions
  • Long-term calcification and stenosis

Our groundbreaking implants are transforming the treatment of life-threatening diseases. Built on Restorex®, our proprietary technology, leveraging Nobel Prize-winning breakthroughs in supramolecular chemistry and polymer technology which enables transformation to the patient’s tissue.

APPLICATIONS

Xeltis aims to improve the standard of care for millions of patients who undergo vascular surgery every year, including hemodialysis access, peripheral arterial and coronary arterial bypass surgeries.

Future expansions for our Restorex® supramolecular polymer technology 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 bioresorbable, non-immunogenic implants that transform into the patient’s own tissue, with a low risk of infection and reduced need for reintervention.
