Is Polyvinylidene Diflouride (Pvdf) Film Biocompatible In The Murine Cochlea?, Robert Maxwell Jaggers

Browse all Theses and Dissertations

Polyvinylidene fluoride (PVDF) film, a biomaterial that is an integral part of a Totally Implantable Sustainable Hearing Aide (TISHA) device, was examined to determine its biocompatibility within the murine cochlea. The biofilm was implanted in the ear using a round window cochleostomy in 7-9 week old male C57BL/6 mice. Three test groups containing seven mice each were implanted with PVDF film. Each mouse received a sham surgery on the non-implanted cochlea. Three test groups were examined at 48 hours, 3 weeks, and 3 months. At the end of this time the mouse was euthanized, the tissue containing the cochlea was …
