The History of Nucleus Cohclear Hearing Implants
Alessandro Volta reports an electrical stimulation using metal rods that are inserted into ones ear canal creating an auditory sensation.
As somebody was undergoing surgery, Djourno and Eyries place a wire on auditory nerve of the patient. This allowed the patient to have clear auditory detection.
House and Doyle report adults who have used technology to their advantage with hearing improvement. The improvement occured when an electrode is placed onto a nerve in the inner ear.
Blair Simmons places an electrode onto another part of the inner nerve. It was used to detect changes in duration and perception of tone.
First single channel cochlear implant is introduced. Over 1000 people (including 700 children) got the implants between 1972 through the mid 1980's.
Cochlear Corporation introduces first multi-channel cochlear implant system. It was a headband that was able to send mulitple channels used to code speech.
Around the same time, another multi-channel implant was being formed in Utah. It had 6 intracochlear electrodes that were connected directly to the externally worn connector. It consisted of most of the modern day features.
In between the evolution of modern day cochlear hearing implants, tests and improvements were generally made on the multichannel implants.
Currently there are only 3 FDA improved cochlear implant systems avaliable in the U.S. All in which have their simularites in technology and have there huge impact on those with hearing issues.
The Cochlear Hearing implant is a surgically implanted neuroprosthetic device that enhances hearing for those who lack it.
