Theraclion Strengthens Its Governance by Appointing Vincent Gardès as Chairman of Its Board of Directors

Regulatory News:

THERACLION (ISIN: FR0010120402; Mnemo: ALTHE), an innovative company developing Sonovein®, a robotic platform for non-invasive varicose vein therapy using High-Intensity Focused Ultrasound (HIFU), announces that its Board of Directors, which met on July 8, 2026, has appointed Mr. Vincent Gardès as Chairman of the Board of Directors, with immediate effect.

A Director of Theraclion since the General Meeting of June 18, 2026, after having served as an observer over recent months, Vincent Gardès succeeds Mr. Claude Lenoir, who had served as Interim Chairman of the Board of Directors since that date and who remains a Director of the Company.

This appointment comes at a pivotal moment for Theraclion, which has recently achieved several major milestones: MDR certification and growing commercial momentum in Europe, the first clinical implementation in China, the submission of the Sonovein® file to the FDA, the granting of a Category III CPT code in the United States, and a recent successful capital increase. The arrival of Vincent Gardès, an experienced executive with a proven track record in the international development of MedTech companies and a specialist in commercial strategy, significantly strengthens Theraclion’s governance.

“I am honoured by the trust placed in me by the Directors of Theraclion. The company has a unique technology, solid clinical results and remarkable momentum across all of its markets: in Europe, where Sonovein® is already adopted in clinical practice, and in the United States, where the fundamentals of market access are falling into place. I look forward to putting my experience at the service of Theraclion, alongside the Board of Directors and the executive team, to reach the next stages of its development and accelerate the deployment of its commercial strategy,” stated Vincent Gardès.

“The appointment of Vincent Gardès is excellent news for Theraclion. His track record in the international development of innovative MedTech companies is exactly what Theraclion needs today. We have been working together for several months; this collaboration is already remarkably smooth and we fully share the same strategic vision. I also warmly thank Claude Lenoir for his interim chairmanship and his constant commitment to our company,” stated Martin Deterre, Chief Executive Officer of Theraclion.
