Bjork-Shiley Heart Valve Prosthesis

Description (Brief)
Thoracic and cardiovascular surgeon Viking O. Björk (1918-2009) had experience with the implantation of many different artificial heart valves at the Karolinska Institute in Stockholm, Sweden, before he teamed up with biomedical engineer Donald P. Shiley (1920-2010). Together they designed a new heart valve prosthesis. This aortic artificial valve was a spherical-shaped tilting carbon disk with a woven Teflon sewing ring. They began testing their valve in 1968 and were ready for the first human implantation in January 1969.
