Tissium is a mission-driven medical device company founded in 2013 , headquartered in Paris , with a production facility in Roncq (near Lille) and an office in Boston . We are dedicated to creating a new era of body repair by leveraging our biopolymer platform to develop innovative solutions in surgery for a positive impact on patients' lives . Tissium's technology is based on research and intellectual property from the laboratories of Professor Robert Langer (MIT) and Professor Jeffrey M. Karp (Brigham and Women's Hospital) , who co-founded the company with Christophe Bancel (CEO) and Maria Pereira (Deputy CEO & Chief Innovation Officer) .

We are developing polymers for atraumatic tissue repair in various applications. Today, these polymers are used for sutureless nerve repair , hernia repair , and cardiovascular sealing . Since our inception, we have raised more than 200 million euros , including 60 million euros in new financing announced in June 2026 . This capital supports the US commercial rollout of COAPTIUM® CONNECT , our FDA-authorized sutureless nerve repair system, and the development of our pipeline.

As TISSIUM moves from development to commercial stage, with COAPTIUM® CONNECT rolling out in the US and a pipeline spanning nerve, hernia and cardiovascular applications, robust clinical evidence is at the heart of our growth.
