title: Biological evaluation of biomaterials for cardiovascular applications: some current results.
abstract: The proper biologic evaluation of biomaterials for blood-contacting applications must include considerations of hemorheologic parameters, species-related differences, and damages to the reticuloendothelial system. Although there are no materials currently available that are completely blood compatible, several smooth-surfaced polymers are quite tolerable in the physiological environment. These include chemically grafted polyacrylamide hydrogels, glow-discharge polymers of silica-free hexamethldisiloxane, and ethyl cellulose perfluorobutyrate.
