Answer 1

Medical implants are products that have to satisfy functionality demands defined by the working environment-human body. They could be used in almost every organ of the human body. Ideally, they should have biomechanical properties comparable to those of autogenous tissues without any adverse effects. The principal requirements of all medical implantsare corrosion resistance, biocompatibility, bio-adhesion, biofunctionality, processability and availability. To fulfill these requirements, most of the tests are directed into the study extracts from the material, offering screens

for genotoxicity, carcinogenicity, reproductive toxicity, cytotoxicity, irritation, sensitivity and sterilization agent residues.
