Abstract
Development of a new steerable electrode array with embedded nitinol shape memory alloy actuators is described in this paper. The risk of damaging the basilar membrane during insertion of electrode array into the human cochlear is expected to be significantly reduced with the ability to redirect the tip of the electrode array at the critical hook region. The final position of this electrode array can also be adjusted to lie beneath the basilar membrane inside the scala tympani for delivery of neurotrophins (growth factors). The bending behaviour of the steerable electrode array and its trajectories during insertion into the scale tympani were predicted using a 3D finite element model. Results from the model have shown that the new electrode array can be steered through the critical ‘hook’ region and be accurately positioned for delivery of neurotrophins.
