Bjork-Shiley Heart Valve Prosthesis

Description (Brief)
Biomedical engineer Donald P. Shiley (1920-2010) and Viking O. Björk (1918-2009) professor of thoracic and cardiovascular surgery at the Karolinska Institute in Stockholm, Sweden, began working on their artificial valve around 1968. They were intent on developing an improved tilting-disk valve that would work in a narrow aortic root. This aortic valve is a spherical-shaped tilting carbon disk with a woven Teflon sewing ring.
