Abstract
A method for sterilizing collagen containing tissue includes crosslinking the tissue to form a crosslinked biological tissue. The tissue is maintained in a hydrated state. The crosslinked, collagen-containing tissue is sterilized by irradiating the tissue with a beam of accelerated electrons. The biological tissue exposed to accelerated electrons is suitable for surgical implantation. The irradiated biological tissue is not significantly degraded following irradiation. The irradiation can be performed on tissue that has been packed in a container in a hydrated state.
