A start-up at the crossroads of science and entrepreneurship

Yves Matton, with his extensive experience in supporting start-ups, plays a central role in Plasana Medical's development. He helps transform scientific discoveries into concrete solutions, accessible to healthcare professionals and patients alike.

Since 2016, Antoine Rousseau has been piloting research into wound healing, supported by the Direction Générale de l'Armement, Agence Innovation Défense, École polytechnique and its Foundation, SATT Saclay and IP Paris' Interdisciplinary Centre for Defence and Security (CIEDS). Unlike the hot plasma of stars, cold plasma is a partially ionized gas at room temperature, suitable for medical applications. In collaboration with Pasteur and the Service de Santé des Armées, his research has demonstrated that this technology has a two-fold advantage: it eliminates pathogens while promoting wound healing. These properties pave the way for promising applications, notably in the treatment of chronic wounds and severe burns.

An innovative technology for medical applications

Plasana Medical has developed a lightweight, portable device capable of applying a jet of cold plasma quickly and effectively to the skin. This technological breakthrough opens up new prospects for the management of chronic wounds, which particularly affect diabetic patients and those suffering from circulatory disorders.

Awarded a prize in Le Point's Palmarès des Inventeurs 2025, the start-up now aims to accelerate the development of its device and obtain the necessary certifications to bring it to market.

A message of inspiration for innovators

Plasana Medical's founders encourage future entrepreneurs to turn their ideas into reality, and to surround themselves with the right partners to transform their research into concrete applications. Antoine Rousseau has a message for researchers and innovators: “If you have good ideas, go for it!"

Plasana Medical has established itself as a start-up to watch closely, with a promising future in medical innovation.
