RTI plans to make MAPC technology-based biologic implants available to its customers for use in orthopedic surgeries in the first half of 2012.About RTI Biologics Inc. RTI Biologics Inc. is a leading provider of sterile biological implants for surgeries around the world with a commitment to advancing science, safety and innovation. RTI prepares human donated tissue and bovine tissue for transplantation through extensive testing and screening, precision shaping and using proprietary, validated processes. These allograft and xenograft implants are used in orthopedic, dental, hernia and other specialty surgeries. RTI’s innovations continuously raise the bar of science and safety for biologics – from being the first company to offer precision-tooled bone implants and assembled technology to maximize each gift of donation, to inventing validated sterilization processes that include viral inactivation steps. Two such processes – the BioCleanse® Tissue Sterilization Process and the Tutoplast® Tissue Sterilization Process – have a combined record of more than two million implants distributed with zero incidence of allograft-associated infection. These processes have been validated by tissue type to inactivate or remove viruses, bacteria, fungi and spores from the tissue while maintaining biocompatibility and functionality. RTI’s worldwide corporate headquarters are located in Alachua, Fla., with international locations in Germany and France. The company is accredited by the American Association of Tissue Banks in the United States.
