Nucleus 6

Cochlear Americas have launched the Nucleus® 6 System, their most advanced hearing solution to date, designed with a clear purpose – to help you simply enjoy smarter hearing.

The announcement doesn’t say when the processor will be available.  It is awaiting FDA approval in the US.  Key features of the processor include combined electro-acoustic stimulation, and wireless connectivity (when the accessories become available).

Fully Implantable CI Patent Application from Cochlear

1 04 2013

Cochlear leaps ahead in the fully-implantable technology race.

Cochlear has submitted a patent application to the US Patent and Trademark Office for a fully-implantable cochlear implant.  While there are already many patents by all manufacturers for these devices, this one seems to go way beyond the state of the art.

The biggest advance seems to be in the surgical technique.  Because the electronics are on a flexible ‘board’ they can be rolled into a cylindrical shape.  Starting with the electrode array, the entire assembly is inserted through the nostril.  Conventional arthroscopic instruments are inserted through the opposite nostril, and also through a small incision in the ear drum.  There is no shaving of hair, no incisions other than the ear drum, and no waiting period before activation.

While the surgical technique is not claimed in the patent, it seems the surgery may be performed with a mild sedative and a local anesthetic.  Because there is no need for swelling to dissipate or incisions to heal, the implant may be activated on the day of the surgery.

To charge the battery (or super capacitor) just keep a charging box next to your bed, and the power is transmitted wirelessly while you sleep.

Key points in the claims:

  1. The electronics are on a flexible substrate, which may be rolled up for nasal insertion.
  2. Use of a supercapacitor instead of a battery.
  3. Insertion of the electrode array through the Eustachian Tube.
  4. Unrolling the substrate so it lies flat in a sinus cavity.
  5. Wireless radio-frequency charging.

New Cochlear Processor Spy Photos

15 03 2013


These photos confirm that Cochlear’s new processor will be available in two versions.  The larger one has an accessory port, which can be used for direct audio input, a lapel microphone, or with earbuds or headphones to check that the processor and audio accessories are working properly.

Notice that two rechargeable battery sizes are shown.  There is also a disposable battery option, and a battery holder that uses two disposable batteries.

New Cochlear Processor

Once again, delivers spy images of a new product!  The CP900 series  from Cochlear, dubbed Nucleus 6 on various web forums,  seems to come in two sizes.  The image shows two different battery sizes, but the processors themselves are different as well.

Cochlear Americas issues a recall

12 09 2011

Quoted from;

Cochlear said in its announcement that all existing recipients with a Nucleus C1500 series implant can continue to use their system as normal.

Cochlear said less than 1 per cent of CI512 implants had failed since its launch in 2009, but that it had identified a recent increase in the number of Nucleus CI512 implant failures.

To be cautious the company had decided to recall the Nucleus CI500 range of implants while it investigates the cause of the problem.

Update @ 19 October 2011: Cochlear’s chief Chris Roberts discusses the hearing implant maker’s recovery since a voluntary recall last September wiped more than $1 billion off its value. Video after the jump, transcript is below the video.  Note that Mr Roberts said ‘The Nucleus 5 externals – nothing’s changed, we just changed one part of the system, the implant, no hearing performance has been compromised.‘… the Nucleus 5 processor is no improvement upon the Freedom.
