Abstract

To address the unmet need to study the microstructure changes in the cochlea that occur with sensorineural hearing loss, we have constructed a miniature flexible micro-OCT catheter that can be inserted into the human cochlea and acquire images with cellular-level resolution. The OCT catheter was designed, fabricated, and characterized. Crucial mechanical properties (flexibility, insertion force) were measured and found to be comparable to those of commercial cochlear implants. These early results suggest that this new device may provide a viable approach for diagnosing SNHL and selecting the most appropriate treatments on an individual patient basis.
