How many electrodes does MED-EL have?

12-
The Standard is the first 12-channel electrode array developed by MED-EL—it’s an innovative design that still remains in use today. It is 31.5 mm long, and like all MED-EL electrodes, it has wave-shaped wires and a straight design that curves naturally within the cochlea.

How many electrodes are in MED-EL implant?

The ABI electrode array features 12 active contacts on a soft pre-shaped silicone paddle, with shaping arms fixed to a polyester mesh. MED-EL’s softest and most flexible electrode arrays designed for the majority of patients and optimised for Structure Preservation and the preservation of residual hearing.

What does the electrode array do?

An electrode array is a configuration of electrodes used for measuring either an electric current or voltage. Some electrode arrays can operate in a bidirectional fashion, in that they can also be used to provide a stimulating pattern of electric current or voltage.

How many electrodes does Advanced Bionics have?

1 Electrode Array Designed for a gentle cochlear insertion,11,12,13,20 the electrodes deliver 120 spectral bands of sound to help you understand speech and enjoy music.

How many Intracochlear electrodes are there on all Nucleus cochlear implants?

10 electrodes
The culmination of more than a decade of research was the prototype University of Melbourne multichannel implant, a fully implanted system with an intracochlear array of 10 electrodes that received power and data from an external speech processor system via radio frequency.

What is a neurostimulator electrode array?

An array defines the collection of contacts that are on one catheter. CPT codes 63655, 63662, and 63664 are for neurostimulator system placed via an open surgical exposure. The contacts are on a plate or paddle-shaped surface. Do not report CPT code 63661 when removing the percutaneous trial electrode (CPT code 63650).

What are cochlear implant electrodes made of?

The use of cochlear implants involves the following materials coming into contact with the human body: silicone, platinum, titanium and ceramics. Platinum is used as the electrode contact. For the Teflon-coated wires between the receiver/stimulator and the electrode contacts, platinum/iridium 90/10 is used.

How is cochlear implant surgery performed?

Cochlear implant surgery is fairly routine and typically performed under general anesthesia. The surgeon will make a small incision behind the ear and sometimes a small area of hair may be shaved away from the incision site. The implant is then placed under the skin and the electrode is inserted into the inner ear.
