Regulations such as the MDR require proof of the biocompatibility of all materials that come, directly or indirectly, into contact with patients or users. A test-based biocompatibility assessment provides reference data that provides a very good basis in the event of unexpected problems and that helps to quickly and directly identify unknown causes. However, there…
DetailsThe ISO 10993-17 standard is part of the ISO 10993 series of standards on biocompatibility. ISO 10993-17 describes the procedures for Toxicological Risk Assessment. In the fall of 2023, a comprehensive standard revision was published after over 20 years. Medical device manufacturers should know, This article will help. 1. Context of ISO 10993-17 1.1 The…
DetailsIn order to evaluate the biocompatibility of standard materials, medical device manufacturers can, in most cases, avoid animal testing. In recent years, the Johner Institute had always succeeded in showing alternatives to animal testing, even when authorities and notified bodies demanded them. Learn here how you can contribute to animal welfare, save money, and bring…
DetailsCytotoxicity testing can be used to test a sample to determine how much it can damage, or even cause the death of, human cells. Standards and legislation require manufacturers to demonstrate that their devices are not cytotoxic. With a good test setup, it is possible to detect whether a sample is 100% cytotoxic, i.e., highly cytotoxic, or…
