Director of Neurointervention Unit
Our team in the angio suite no longer has to worry about their own radiation exposure - no more heavy lead aprons, no compromise on precision – instead a physical protective barrier with real-time dose monitoring. A safer workplace for our team ultimately means better care for our patients!
Head of Neuro Dpt.
This cabin is like a wall between the X-ray machine and the operator, and finally, when you look at the results, you have 91% of dose reduction for the body, you can remove your lead apron, but above all, the field of X-rays is much reduced […] If you do 300 procedures per year with the cabin, which is a lot for a neuroradiologist, you will receive 0.4 mSv which is much below the minimal dose for the common population […] Finally, with the cabin you are more or less like anyone
Interventional Neuroradiologist
I would say that Nova-X® helped me to come back to work in good conditions, drastically reducing back pain. I discovered a new way of working which brings a lot of benefits beyond the comfort of no wearing lead apron.
Founded in 2024, Cathpax designs, develops and commercialises innovative, full-body, team-wide radiation protection systems for cath lab staff during interventional procedures. Spin-off of the Lemer Pax group, the company leverages more than 50 years of innovation in the radiation protection field. A pioneer in ionising radiation protection since the 1970s, Lemer Pax spent the past two decades developing groundbreaking innovations to advance its mission of Protecting Life® over the last two decades. The group has created cutting-edge radiation protection materials and technologies used in thousands of products worldwide. Today, Lemer Pax covers three major areas of expertise through three different entities: Lemer Pax (Civilian nuclear sector, radiopharmacy, nuclear medicine and radiology), GMP (therapy radioisotope production) and Cathpax (interventional medicine).
Developed over more than 10 years of research & development, Nova-X® is Cathpax’s second-generation radiation protection system. Protected by more than 10 patents, Nova-X® is currently the only available solution on the market providing 2 mm lead equivalence. The system features a unique dose monitoring system displaying real-time dose rate reduction (Dosicath®). Nova-X® also boasts a built-in laser system that projects two green laser beams onto the floor, clearly marking out a controlled zone for Healthcare providers (Laserguard®). Thanks to all these unique features, Nova X® drastically improves cath lab staff safety and comfort, promoting stress-free working conditions through efficient full-body and team-wide protection against radiation injuries, ultimately benefiting the patient.
Nova-X® received CE-Mark certification in 2025 and the company expects to obtain FDA approval over the course of the next two years. Based in Nantes, France, Cathpax aims to become the world leader in full-body, team-wide radiation protection in interventional medicine.
