Due to its favorable properties, collagen is increasingly used in medical devices. Nowadays, the necessary sterilization of this sensitive material may be conducted only by ethylenoxide and γ irradiation. To overcome the drawbacks connected to those methods, a new sterilization procedure using supercritical CO2 and the addition of small amounts of sterilization aid is successfully tested.
