CryoLife® was founded in 1984. In 1995, CryoLife acquired the rights to the O'Brien Stentless Aortic Porcine Bioprostheses. These clinically proven products represent the "state-of-the-art" in xenograft technology and bring a new and complementary dimension to CryoLife's commitment to improving the quality of life for patients who require such devices. The company acquired the Ross pulmonary porcine heart valve in 1997. Both of these valves are manufactured in Marietta, Georgia.
