Symphonix Devices has submitted a premarket approval application to the US FDA for its semi-implantable devices for treating sensorineural hearing loss. The Vibrant P and Vibrant D soundbridges use an external audio processor and an implantable floating mass transducer, the size of a grain of rice, to convert acoustic sound to vibrations inside the middle ear. Since no portion of the device sits in the ear canal, problems associated with a traditional hearing aid, such as occlusion, feedback and external ear infections are potentially eliminated, said the San Jose, California-based company.
