ca. 1952-1958
Two Hufnagel rigid plastic aortic valve and aortic graft units, and one Hufnagel aortic valve, donated by J. Karl Poppe, M.D., in September 1978. The graft consists of a valve in a plastic tube with open ends and white plastic holders in grooves along the edges. The valve is a plastic ball-and-cage design. All are in good condition.
One of two digital photographs (with 78-4_2_3b.jpg) of two Hufnagel rigid plastic aortic graft-and-valve units and one Hufnagel artificial aortic valve, used during the period 1952-1958. This image shows the artificial valve. Set next to it on the gray counter is a small blue box. A ruler has been placed in the foreground for size comparison.
