Surgery, before implants were developed
Microsurgical techniques and stapes surgery made the idea of surgical implants possible. An electrode was directly applied to the acoutic nerve of a deaf person and the nerve stimulated by electricity. -
Period: to
Cochlear implant Development
-
Circuit development to aid cochlear implant development
Advances in cardiac pacemakers increased knowledge of biocomaptible materials, insulation of elctrodes and the effects of electrical simulation. As a spin off of space research, smaller and more powefull electrical circuits were developed. -
Further cochlear development started
Inspired by his close relationship with his deaf father, Graeme Clark begins researching the possibilities of an electronic implantable hearing device. Graeme Clark began researching possibilities of an elctronic implantable hearing device. -
First multi-channel impalnt was made
cochlear implant projects were trailled in 1976 Professor Graeme Clark of the universoty of melbourne made the first multi-channel implant. he is considered to be the fatheer of cochlear impants. -
New designs were being developed as well as products being tested
Professor Graeme Clark receives research grant for "The Development of a Hearing Prosthesis". Professor Clark, determined to discover a way to get the electrode placed securely in the inner ear – finds a solution by experimenting with a blade of grass and a small turban shell on the Minnamurra Beach in New South Wales, Australia. He also discovers the importance of a graded stiffness in the design of the electrode. Mona Andersson was the first recipient of a bone conduction hearing implant. -

First receipent experimented with was successful
Rod Saunders was the world's first cochlear implant recipient to show the benefit of multi-channel stimulation. After his sound processor was turned on, Rod excitedly jumped up and saluted, indicating that he could hear again. -
First cochlear recipient
Rod Saunders was the world's first cochlear implant recipient to show the benefit of multi-channel stimulation. After his sound processor was turned on, Rod excitedly jumped up and saluted, indicating that he could hear. -
New similar device used by Rod Saunders and more devices to come
Rod Saunders used a portable speech processor: (PSP) and handheld microphone this year after the success last year. A medical device group, Nucleus, becomes interested in the potential of Professor Clark’s work. Eventually, Nucleus and Cochlear (the company was officially formed later during the early 1980’s) and the Australian Government would partner to develop a commercially available implant and bring it to market. We know it today as the Nucleus® multi-channel cochlear implant. -
Second recipient, George Watson
Portable speech processor with magnet-less headset is created. George Watson, second recipient, spends time in programming with Joe Tong. -
Paul Trainor, developer Nucleus implant
Paul Trainor is given AU$4million to start commercial development of the multi-channel cochlear implant. Trainor was the owner of the Nucleus group, which included Telectronics, an Australian heart pacemaker firm. Trainor directed the team of expert bio-engineers that would ultimately bring the Nucleus multi-channel cochlear implant to commercial market. -
Rod Saunders, processor upgrade
In 1982, three years after receiving his cochlear implant, Rod Saunders receives a new wearable speech processor (WSP). -
First Nucleus implant
The first commercial Nucleus implant (the Nucleus CI22) was implanted at the University of Melbourne. The recipient was Graham Carrick, aged 37 years. The ability to hear again marked a life changing moment for Graham, providing him with confidence and hope. -
Cochlear Americas office established
A small team establishes the Americas office outside Denver, Colorado. -
FDA approves Nucleus implant system
Nucleus established as the first multi-channel cochlear implant system to obtain clearance from the FDA for use by profoundly deaf adults 18 and over. The Nucleus Mini22 implant with the WSP (Wearable Speech Processor) was the first multi-channel device to receive FDA pre-market application approval. -
First two paediatric implant recipients
The first two research paediatric cochlear implant procedures take place at the Royal Victorian Eye and Ear Hospital. Professor Clark keeps company with the first two paediatric cochlear implant recipients; Scott Smith (10 years) - first child - and Bryn Davies (five years) -- second child 1985. Clinical trials for cochlear implant for children begin in the US. -
First paediatric Nucleus recipient
Holly McDonell, at the age of four, is the first paediatric recipient of a commercial Nucleus cochlear implant. She still has her original implant and has had five sound processor upgrades. -
New mini speech processor introduced
Nucleus 22 recipients are upgraded from their original WSP to the smaller mini speech processor (MSP). New processor is much smaller and lighter than the WSP; it has the MPEAK speech coding strategy, providing improved performance; and the smaller size makes it more suitable for children. -
US FDA approves Nucleus Cochlear Implant system for children age 2-17
The US FDA approves the Nucleus Cochlear Implant System for children aged 2 to 17 years, the first cochlear implant to be approved by a regulatory body for use in children. Increasing number of impants were performed. many on children. -
speech proccessor design improvments
Huge improvements in speech processor design and sound quality users. this meant patients could recognise speech and music patterns more realisticly. cochlear implants consist of a 22 channel stimulator in a titanium capsule with platium electrodes. -
10,000 recipient mark
Cochlear celebrates the 10,000th Nucleus recipient. Spectra processor upgrade for Nucleus 22 users. This utilizes SPEAK, an improved speech coding strategy providing fuller, richer, more natural sound. -
Product innovation
The first implant capable of performing Neural Response Telemetry (NRT™), used to provide an objective measurement of the hearing nerve’s response to electrical stimulation (NRT). This allows medical professionals to test the hearing nerve to make sure it is functioning properly. -
Further product inovation
SPrint – the powerful bodyworn speech processor is introduced. SPrint™ technology is based on a powerful Digital Signal Processor (DSP). The first MRI-safe implant up to 1.5 tesla is introduced. -
BTE inovation
The first multi-channel BTE processor introduced – the ESPrit. A speech processor worn entirely behind the ear, freeing recipients from long cables and extra components. This innovation eventually benefits the first cochlear implant recipients, giving them option of the smaller behind the ear model. -
Contour
