TY - GEN N2 - Digital scan of a 35mm slide. Black-and-white side-by-side comparison of two models of disc-type artificial heart valves. On the left is "Model 6500" with stellite disc. On the right is "Model 6520" with a disc of UHDP (ultra high density plastic). Both models have metal cages with white mesh cloth-covered rings.
