Implantable converter for cochlea implants and implantable hearing aids |
摘要 |
The invention relates to an implantable electromechanical converter for receiving oscillations from an ear ossicle and for converting them into an electrical voltage, for use as a microphone for a cochlea implant or an implantable hearing aid, consisting of one or more piezoelectric converter elements ( 11 ) housed in a hermetically sealed hollow body ( 2 ) made of a biocompatible material. The converter is characterized in that the hollow body has a thin shell ( 9 ) which is connected with its interior side to the piezoelectric converter elements and which can be coupled with its exterior side to an ear ossicle, and which is held by a stable edge ( 10 ), whereby the stable edge can be coupled to a counter-support in the middle ear space. |
