Profusa Expands in Europe with French Vascular Surgery Leader
Paris partnership brings Lumee Oxygen monitoring to practices covering 8% of France’s CLTI cases.

Profusa (NASDAQ: PFSA) is extending its footprint in European healthcare with the addition of one of France’s top vascular surgeons to its customer base. The company announced this week that Pr. Yann Gouëffic, M.D., Ph.D., professor of vascular surgery at Groupe Hospitalier Paris Saint Joseph, will adopt Profusa’s Lumee™ Oxygen monitoring technology for use in both his practice and clinical studies.
The collaboration marks a significant milestone for the digital health firm, as Gouëffic and his affiliates treat approximately 8% of all critical limb-threatening ischemia (CLTI) cases in France. CLTI, a severe form of peripheral arterial disease, affects thousands of patients annually and often leads to amputation if not properly managed.
A Surgeon’s Endorsement
Pr. Gouëffic, who has more than two decades of experience in treating peripheral arterial diseases, described the technology as transformative. “My practice, in addition to those of my affiliates, treats a meaningful number of CLTI cases in France, and I believe Profusa’s Lumee technology to be a game changer in our patient care program and a true advancement clinical disease governance,” he said.
He emphasized the importance of continuous monitoring, not only during surgical intervention but also throughout the recovery process. “Real-time oxygen monitoring data for patients suffering from CLTI, while critical during surgery, is equally as important during recovery at home. Given the large clinical need, I believe offering Lumee to our patients will result in improved outcomes,” Gouëffic added.

Strengthening Profusa’s Market Reach
Based in Berkeley, California, Profusa develops tissue-integrated biosensors designed to provide continuous, medical-grade data that supports clinical decision-making. The addition of Gouëffic, who also leads the FRANCE-PAD network of six high-volume hospitals, significantly increases the company’s influence in Europe. Collectively, his network represents around 8% of lower limb peripheral artery disease treatments across the country.
Ben Hwang, Ph.D., Chairman and CEO of Profusa, welcomed the new collaboration, stating:
“Our Lumee oxygen monitoring system continues to be validated with the steady addition of new surgeon customers to our network. We warmly welcome Pr. Gouëffic and look forward to advancing vascular disease management with our commercial and clinical collaboration. We are also excited to serve Pr. Gouëffic’s affiliates, which, all combined, account for approximately 8% of CLTI cases in France. We believe we provide a differentiated, real-time biochemistry monitoring platform technology for use at the clinic and at home, and are focused on serving a large endovascular market need, estimated at over 300,000 procedures a year in Europe.”
A Growing Opportunity
The European market for endovascular procedures is estimated at more than 300,000 annually, and Profusa sees Lumee as a differentiated solution to meet this demand. The company’s strategy includes building partnerships with leading physicians to accelerate the adoption of its monitoring platform, both in hospitals and in patients’ homes.
By aligning with Gouëffic and his affiliates, Profusa gains access to a large population of patients who may benefit from real-time oxygen monitoring. This step not only strengthens the company’s European expansion but also reinforces its commitment to tackling complex vascular conditions with innovative technology.
