<p>A method for reducing the number of free radicals in an implantable medical component (24) requiring sterilization includes the steps of packaging the component in an oxygen-resistant container (12), sterilizing the packaged component, and exposing the packaged and sterilized component to a gas capable of combining with free radicals. The step of packaging includes vacuum sealing the component in an oxygen barrier bag. The step of sterilizing includes exposing the packaged component to radiation such as gamma radiation. The step of exposing the packaged and sterilized component to a gas capable of combining with free radicals includes placing the packaged component in a pressure vessel and introducing pressurized hydrogen gas into the vessel for a period of time.</p> |
