Cochlear implant and accessories made by Nucleus Ltd

Made by Nucleus Ltd in Lane Cove, Sydney, New South Wales, Australia, 1983.
Cochlear Limited was founded in Australia in 1981, based on Australian research by Dr Graeme Clark in developing the cochlear implant or bionic ear, an Australian innovation. By 2006 it had become an international leader in the manufacture and sale of cochlear implant systems.

This item is the first commercial model of a speech processor produced by Cochlear Limited. It was designed for use with the Nucleus 22 implant developed in 1983 which, in 1985, was the first multi-channel implant and speech processor system to receive approval for use by the US Food and Drug Administration.

This speech processor is the first of a number of generations of devices produced by Cochlear with continual improvements in sound processing and reduction in size. It represents Cochlear's design strategy of making a flexible cochlear implant with sophisticated sound processing in the externally worn speech processor, allowing the recipient to take advantage of improvements in technology without surgically replacing their implanted device.

Notes

This is an example of the first commercial version of the cochlear implant and speech processor developed by Nucleus, later known as Cochlear. This type of device was first implanted in September 1982 in Melbourne as part of an Australian clinical trial. Worldwide trials followed and the device was given the US FDA approval in October 1985. It was the first multiple electrode cochlear implant to be approved for clinical use by any health regulatory body. It was later approved for us in Japan, Europe and the UK.

The speech processor is the first wearable speech processor developed by Nucleus.

History

Notes

Some great ideas need enormous commitment and cooperation to bring them to fruition. Graeme Clark's father was a deaf man in a hearing family and society. He was a pharmacist and often had to ask his customers to 'speak up' about their medical problems - which embarrassed him and them.

In 1967 Graeme embarked on a long journey towards fulfilling his dream of helping deaf people 'hear' the spoken word again. For ten years his research into electrical stimulation of the auditory nerve via an implant into the cochlea (a structure in the inner ear shaped like a snail shell) struggled along on animal experiments and university grant funding.

In 1974 a telethon on Channel 10 in Melbourne generated enough funds to take his work to the prototype stage and test it in a human patient, Rod Saunders. The 'bionic ear' worked: Rod could perceive sound again.

This demonstration encouraged the Australian government to finance commercialisation of the 'bionic ear'. The financing of the cochlear implant's manufacture and marketing became a remarkably successful joint venture. The three-way partnership was between researchers at the University of Melbourne, the federal government and a medical equipment exporter called Nucleus. This partnership led to the formation of a string of Cochlear enterprises in the US, Japan and Switzerland including Cochlear Pty Ltd in Australia.

The Nucleus® 22, introduced in 1983, was the first use of a 22-channel implant. This allows the user to distinguish a wide range of sound frequencies and is the world's most widely used cochlear implant system. By the early 1990s Cochlear Pty Ltd was making a profit and Professor Clark was earning royalties.

In 1994, after 5 years of lobbying, the implant was approved by Japanese health insurance companies, opening up a market of up to 50 000 profoundly deaf people.

Nucleus® 24 Contour, introduced in 1999, uses a pre-curved electrode. The electrode is made with the curved shape of the cochlea, improving the sound quality and simplifying surgery. Its speech processor incorporates the microphone and processor behind the ear, eliminated unnecessary wires. It won an Australian Design Award™ in 2000.

By the end of the century there were over 24 000 Nucleus users in 50 countries worldwide, and the total time that all Nucleus systems had been in use was over 142 000 years (Nucleus implant years).
