Degradative effects of conventional steam sterilization on biomaterial surfaces

Prior to implantation trials in animals, the effect of steam sterilization on the surface properties of metallic and coated biomaterials was studied. Pure germanium plates and cast surgical Vitallium discs and subperiosteal implants were treated to present three standard types of biomaterials surfaces prior to steam sterilization, ranging from scrupulously clean, high-energy metals to uniformly low-energy organic layers. Both before and after sterilization, the sample surfaces were characterized by a variety of nondestructive physiochemical techniques. The results indicate that steam sterilization is likely to compromise the properties of otherwise carefully prepared biomedical implants by depositing hydrophobic organic and hygroscopic salt contaminants over the implant surfaces.

Physiochemical Properties of Stabilized Umbilical Vein

From the State University of New York at Buffalo, and the Calspan Corporation, Buffalo, New York. The glutaraldehyde-stabilized human umbilical cord vein has come to a successful stage of routine use for peripheral vascular reconstruction only after passing through the developmental stages of all major new biomedical products: enthusiasm, disenchantment, search for product flaws and their elimination, and, finally, careful documentation of all those procurement and processing steps necessary to satisfy the most stringent regulatory agencies. We are rewarded, now, by having achieved at least 4 years of excellent patency in human subjects with functional grafts in the most difficult peripheral locations. Their stabilized veins have been changed only moderately by lipid uptake and by fixation to the surrounding muscles and other tissues. And the thromboresistant surface properties of the luminal wall, upon which their original processing was premised have been maintained. I, 2
