A practical session on biological evaluation of medical devices: ISO 10993, US FDA & EU MDR expectations, and chemical characterization. Hosted by TUV SUD with Medtronic.
Join the RAPS Twin Cities Chapter for a practical, collaborative session on the biological evaluation of medical devices hosted by TÜV SÜD in partnership with Medtronic. Bringing together regulatory, toxicology, and testing-lab perspectives, this event is designed to help regulatory professionals confidently plan, interpret, and defend the biocompatibility evidence used to support device safety across global markets.
Through real-world examples and expert dialogue, attendees will explore how the ISO 10993 framework is applied in practice, how US (FDA) and EU (MDR) expectations differ, and how chemical characterization and toxicological risk assessment are reshaping biological evaluation. The session emphasizes clarity, regulatory relevance, and effective cross-functional communication between regulatory, R&D, and testing partners.
By the end of this session, participants will be able to:
