The Internal Part of Cochlear Implant with Detachable Electrode

Introduction The presented scientific work shows two prototypes of the implantable part of a cochlear implant with an electrode developed by the author that allows its detachment from the implant body. The advantages of this prototype are that in medical indications for explantation of the inner part of the cochlear implant it is possible to remove only part of it - the body or the electrode itself.

Materials and methods Consideration was given to the materials used for manufacturing the electrode of the implantable part, as listed in the specifications of the respective companies.Two prototypes were created.

• The first prototype has the same length. The possibility to detach the electrode from the base is essentially new.

• The second prototype differs from the standard CI length (it is longer). The power supply difference was estimated for both prototypes. Finished prototypes with a removable implantable part of the cochlear implant were also tested under real conditions of humanoid models.

Results The calculations and the results of the CI prototypes with detachable electrodes from the body of the implantable part of the cochlear implant have proven their theoretical and practical feasibility.

Discussion In cases of medical indications for the removal of the implantable part, the correctly placed electrode could be retained. Once the pathological process has been removed, the electrode can be placed on the new body of the implantable part. This is crucial for maintaining the structures of the inner ear. The second prototype is important for cases of regular MRI or CT checkups, operations in this region or for patients who do not want to show their hearing problem.
