DESCRIPTION DE L'ENTREPRISE 

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 a total of 170 million euros. Our latest fundraising round, which concluded in April 2023, resulted in 50 million euros in additional funding. This infusion of capital provides us with the necessary resources to finance the commercialization of our first products.
