About SamanTree Medical

SamanTree Medical proposes a breakthrough innovation for checking complete tumor removal during surgery: the Histolog™ Scanner. This novel imaging modality is a direct support during cancer surgery to achieve the common goal of improving patient quality of life by decreasing rates of reoperation.

The team is fully dedicated to bringing the Gold Standard in the operating room, enabling margin assessment, in real time, at the histological detail.

SamanTree Medical SA was founded in December 2014 and is a spin-off of the EPFL (Ecole Polytechnique Fédérale de Lausanne).

Following the promising clinical results achieved with its CE mark device, SamanTree Medical has recently closed a CHF 9.5 Million Series A financing round for developing its commercial operations.
