content: This Muller-Littlefield Aortic Valve has a tri leaflet design and is 1-34 mm diameter. It is housed in a metal jar with a lid. It made of Teflon cloth with salvaged edges to keep the fabric from fraying. In a study of 23 patients (between 1961 and 1963), it was found that the valves stiffened and the fabeic would tear.
