Title
(EN) Electrode assembly for cochlear implant
Abstract
(EN)
A cochlear implant electrode assembly and a method for affixing it to a bone (36) in the ear. An electrode ball (16) or unfixed turns is made from one end of each wire (6) leading to the electronics part of the implant, a corresponding attachment hole (40) is drilled in the bone, and the ball is affixed to the hole without the use of fixation devices by tapping the turns into the hole (40). A further aspect is directed to the method of making a cochlear implant electrode (16).
