Progress in Development and Application of the University of California at San Francisco/Storz Multichannel Cochlear Implant

A four-channel bipolar cochlear implant developed at the University of California at San Francisco through a long series of animal experiments, engineering development studies, and speech processor design-optimization studies with experimental prosthetic devices in patients, is now being applied in a clinical investigation, as a joint project of the UCSF group and the manufacturer, Storz Medical Instruments.
