Investigation to Evaluate the Safety and Effectiveness of Cochlear Implantation in Children and Adults With Unilateral Hearing Loss/Single-sided Deafness

"The Cochlear™ Nucleus® CI systems are designed to provide useful hearing. The system works by converting sound in the environment into electric pulses that stimulate the auditory nerve, allowing the brain to perceive sound. The Cochlear™ Nucleus® CI system has implanted and external components.~Implanted component:~The CI is surgically implanted under the skin behind the ear. It includes a receiver/stimulator to receive and decode the electrical signals from the sound processor and an electrode to deliver these signals to the cochlear.~External components:~The external components include a sound processor, and associated accessories and cables. The system is programmed by a Cochlear proprietary programming system, Custom Sound®."
