Talk will be in the Landtagssaal, Overflow transmission to Rittersaal, Herrensaal, and Prälatensaal Summary of the Talk of Sabine Reinfeldt IMPLANTABLE BONE CONDUCTION DEVICES – DEVELOPMENT AND CHALLENGES This talk will contain an overview of bone conduction devices (BCD) available today and challenges when developing implantable devices. These devices need to be powerful and small enough, have good attachment and transmission to the bone, and be effective and safe for patients. In this talk, challenges in the Bone Conduction Implant (BCI) investigation will be presented and discussed, finally leading to a product ready for clinical use. The BCI is an active transcutaneous BCD (atBCD) developed in collaboration between Chalmers University of Technology and Sahlgrenska University Hospital, in Gothenburg, Sweden. It has been in clinical investigation 2012-2022 with a total of 16 patients in Gothenburg and Stockholm. Before the clinical study, there were numerous preclinical studies. In summary, this talk will give an overview of BCDs, discuss challenges with implantable BCDs, present some of our BCI research, and give a bit of a recapitulation of the journey from idea to reality. Summary of the Talk of Christof Röösli Several pathways contribute to bone conduction stimulation hearing. The relevance of different pathways has been evaluated by experimental methods. These experimental methods will be discussed with a focus on the fluid pathway. Is the cochlea activated via intracranial fluid without bone vibration? Additionally, the effect of different stimulation location and coupling methods of bone conduction transducers was experimentally analysed and the findings will be shared. Speakers: Sabine Reinfeldt is an Associate Professor in Biomedical Engineering at Chalmers University of Technology in Gothenburg, Sweden. She started her research in bone conduction hearing as PhD student in 2003 in engineering aspects of bone conduction physiology and preclinical studies for a bone conduction implant. Her research has then continued with preclinical and clinical studies for the bone conduction implant and also included methods for fitting of bone conduction devices as well as applications within hearing and balance diagnosis. Prof. Dr. med. Christof Röösli is a Professor of the Department of Otorhinolaryngology, Head and Neck Surgery at the University Hospital Zurich, Switzerland. His clinical interests are in otology, cochlear implants, and skull base surgery. After his training in Luzern and Zurich, he spent a year at the Massachusetts Eye and Ear Infirmary in Boston for a research fellowship, before he became a faculty member in Zurich. He is currently the head of the Swiss otology group. He has published more than 130 peer reviewed articles and holds 10 national and international awards. His main research interest is bone conduction hearing and bone conduction implants, but also cochlear implants, vestibular schwannoma and middle ear mechanics. His research is funded by the Swiss national Foundation.
