Founded in 2015 in Nantes (Upper Britany, France), i-SEP is a medtech specialized in intraoperative autotransfusion and Patient Blood Management. At i-SEP, we have developed, patented and now markets an innovative technology for the recovery and separation of blood components.

Together with our clinicians, we develop unique Patient Blood Management solutions for improved patient & stakeholder benefits.

We work closely with specialized clinicians with the aim of improving patient benefits, simplifying physicians’ workflow and helping reduce healthcare cost.

Our innovation brings significant added value compared to currently available solutions, particularly in terms of blood quality.
