Said Dr Steven Elias, director of Center for Vein Disease Englewood Health Network NJ. He insisted that this technology "will be great for patients".

"We are proud that SONOVEIN, our technology, was chosen to be assessed by renowned experts in vein treatments. We are hoping to have soon the first US patients treated with our extra corporeal system for their varicose veins. Our qualitative pre-clinical studies, the CE marking since 2019 and our clinical data from our European centers should support a fast approval for our pivotal study" said Michel Nuta, MD, Chief Medical Officer, Vice-PresidentVeins Theraclion SA.

About Theraclion

Theraclion has developed an innovative echotherapy solution using High Intensity Focused Ultrasound for the treatment of varicose veins, SONOVEIN®. The treatment solution, which obtained CE marking in April 2019, is based on the leading-edge echotherapy treatment expertise developed by Theraclion over years for non-invasive ablation of breast fibroadenomas and thyroid nodules using its ECHOPULSE® solution. Further improvements to the ECHOPULSE technology are the foundation for SONOVEIN to provide the only non-invasive ablation therapy for varicose veins. This procedure allows for treatment without a catheter, chemical injection, or incision. An operating room is not necessary, and the treatment can be performed at a doctor's offices or in clinics, as well as in hospitals. Venous pathology is widespread worldwide and generates around 5 million treatment procedures per year, according to Millennium research Varicose Vein Device Market Study 2015. Theraclion's technological solutions are based on high-tech ultrasound medical devices that are precise and easy to use for practitioners.
