Patent ID: 7438850

Claim:
A sterilization method for producing transplantable or implantable biological material of animal or human origin, characterized in that it comprises four sterilization steps that succeed one another in the sequence given below and have a combined chemical and physical effect: 1. Treatment of the source material in an antibiotic solution to prevent the growth of microorganisms and to separate them; 2. Further treatment of the material in deoxycholic acid to prevent the growth of microorganisms and to separate them, in combination with a downstream first rinsing process in an aqueous solution for removing the deoxycholic acid and for rinsing the separated microorganisms from the surface; 3. Further treatment of the material in a surface-active lipoprotein solution with a hemolytic, antibacterial, antiviral, and separating effect on the microorganisms and for further removal of the deoxycholic acid, in combination with a subsequent second rinsing process in aqueous solution; and 4. Further treatment of the material in primary alcohol with a fungicidal, bactericidal, and antiviral effect for further combined separation and complete destruction of the microorganisms, in combination with a subsequent third rinsing process in aqueous solution.
