Born of more than ten years of interdisciplinary research, the start-up Plasana Medical is developing a medical device that uses a multi-jet cold plasma system to accelerate wound healing. This innovation stimulates the proliferation of skin cells, promotes the formation of new blood vessels and the production of collagen, offers high antimicrobial efficacy, and boosts the immune system. Intended for severe burns and chronic wounds, it is suited to both military and civilian applications. Plasana Medical has recently raised four million euros to accelerate the development of its device, enabling it to conduct clinical trials, a key step in the transfer of this technology into the medical field.
