Electrical stimulation with multichannel electrodes in deaf patients.
Design and function of a 6- or 8-channel electrode assembly, which was introduced through the round window into the scala tympani, are described. Two different receiver systems, a more simple one with reed contacts and a more complex one in hybrid technology, are also described. Signal and energy are delivered transcutaneously via inductively coupled coils. The results of the electrical tests are described and discussed.
