Claims19
A sterilized collagen-containing biological tissue suitable for implantation comprising a crosslinked, hydrated collagen-containing tissue irradiated with a beam of accelerated electrons.
A packaged sterilized collagen-containing biological tissue suitable for implantation comprising a crosslinked, hydrated collagen-containing biological tissue sealed in a container and exposed to electron-beam radiation.
A collagen-containing biological tissue suitable for implantation wherein said biological tissue comprises tissue irradiated with a beam of accelerated electrons, and wherein said biological tissue has at least one improved performance characteristic relative to a tissue not irradiated with accelerated electrons, and wherein said improved performance characteristic is selected from the group consisting of greater softness, greater kink resistance, improved suturability, greater tensile strength, no loss of tensile strength, increased effective orifice area, decreased pressure gradients, and enhanced durability.
