The workshop at the Empa aims to bring together people involved in the field of medical implants, from the manufacturing/development until their clinical use. Through expert presentation and discussion rounds, different aspects of implant/devices corrosion related reliability/durability issues will be discussed. One focus will be on "invisible failures". In fact, current understanding of the material-biology interactions shows that macroscopic manifestations of implant and medical-device failure, such as fractures or the release of wear particles, are already documented. However, the underlying processes that lead to the formation of micro- and nanoscale corrosion products, ionic leaching (see figure), and their consequences remain poorly understood.
The European Federation of Corrosion working group on "Corrosion of Medical Implants and Devices organizing this event was created in response to the still limited understanding of how medical materials interact with biological matter, and to the growing number of reported failures, suggesting that the associated risks to material stability and function are sometimes significantly underestimated. New medical devices and materials entering clinical use also raise scientific questions regarding their chemical stability and biocompatibility.
