Long-term drug delivery to the inner ear for neuroprotection might improve the outcome for hearing disabled patients treated with a cochlear implant (CI). Neurotrophic factor (NTF) producing cells encapsulated in an alginate-matrix, to shield them from the host immune system and to avoid migration, and applied as viscose solution or electrode coating could address this requirement. Both application methods were tested for their feasibility in an artificial human cochlea model. Since both strategies potentially influence the electrode implantability, insertion forces and coating stability were analyzed on custom-made electrode arrays. Both, injection of the alginate-cell solution into the model and a manual dip coating of electrode arrays with subsequent insertion into the model were possible. The insertion forces of coated arrays were reduced by 75% of an uncoated reference. In contrast, filling of the model with non-crosslinked alginate-cell solution slightly increased the insertion forces. A good stability of the coating was observed after first insertion (85%) but abrasion increased after multiple insertions (50%). Both application strategies are possible options for cell-induced drug-delivery to the inner ear, but an alginate-cell coating of CI-electrodes has a great potential to combine an endogenous NTF-source with a strong reduction of insertion forces.
