The authors report on an actuated positioning device for a cochlear prosthesis insertion procedure. The device consists of multiple high-aspect ratio fluidic actuator chambers integrated with a high-density silicon cochlear electrode array and manufactured in a tapered-helix form. Actuation chambers with cross-sectional sizes as small as 40 × 200 μm and lengths of 30 mm have been fabricated using flexible polymers. The device will allow for low-resistance basilar insertion of a stimulating…

Toward steerable electrodes. An overview of concepts and current research.
TLDR
This article provides a short overview of concepts and actuator mechanisms investigated in the past and present with the objective of developing a steerable electrode array for an individualized insertion process.
Determination of the curling behavior of a preformed cochlear implant electrode array
TLDR
The results indicate that the risk of intracochlear trauma can be reduced if the specific curling behavior of the electrode carrier is incorporated into the insertion algorithm.
A 32-Site 4-Channel High-Density Electrode Array for a Cochlear Prosthesis
This paper describes a 32-site 4-channel high-density intracochlear electrode array. Combining MEMS-based processing technology with active circuitry, the thin-film device realizes a stimulating site
Magnetic Guidance of Cochlear Implants: Proof-of-Concept and Initial Feasibility Study
TLDR
A magnetic guidance concept in which a magnetically tipped cochlear implant is guided as it is inserted into the cochlea is proposed, and it is concluded that scale–down effects are negligible but the magnet dimensions should be increased by approximately four times.
Study of the Carrier-Aided Thin Film Electrode Array Design for Cochlear Insertion
TLDR
The concept of enhancing a Parylene TFEA with Kapton tape as a simpler carrier for cochlear insertion has been proved to be feasible and indicated that even the T FEA is ultra-flexible and that its bending stiffness should not be neglected in the design or selection of its carrier.

Depth and quality of electrode insertion: a radiologic and pitch scaling assessment of two cochlear implant systems.
TLDR
The preformed spiral array of the Clarion device allowed deeper electrode insertion compared to the Nucleus-22 device, however, depth of insertion did not translate into better pitch placement and open-set speech discrimination scores in either group of implantees.
Multichannel intracochlear electrodes: Mechanism of insertion trauma
TLDR
Fresh human temporal bone preparations were created to allow direct intracochlear observation during round window insertion of a free‐fitting multichannel intrac Cochlear electrode array, and the path taken by the electrode, point of first resistance, and any resulting damage were documented.
