Gentle insertion, secure fixation: Evaluating the electrode holder of the Cochlea Hydrodrive

Abstract

The slow and steady insertion of cochlear implant electrode arrays using automated insertion devices promises gentle implantation with potentially better hearing results for patients. The Cochlea Hydrodrive is a cost-effective and precise hydraulic insertion tool, which enables ultra-slow electrode insertions. In this study, we present the experimental evaluation of the electrode holder for this device, focusing on secure electrode fixation, handling and release in order to increase reliability for future clinical applications.
