Novel Cochlear Implant

The project presents an innovative strategy to improve cochlear implant reliability by addressing two significant complications: infections caused by biofilm formation and insertional trauma during surgery. To combat infections, the design incorporates an antibacterial hydrogel coating made from sulfobetaine methacrylate (SBMA) and embedded with vancomycin, applied via a RAFT polymerization process. This coating is intended to prevent biofilms from developing on the silicone surface of the electrode array, thereby reducing inflammation and the risk of revision surgeries.

Additionally, the design utilizes a robot-assisted surgical device to insert an electrode array coated with a Flexdym polymer and a thin film of SBMA. This approach aims to achieve more precise and controlled placement, reducing the mechanical trauma typically associated with manual insertion. Together, these innovations are poised to significantly enhance the longevity and performance of cochlear implants, ultimately leading to better hearing outcomes and an improved quality of life for patients with severe hearing loss.
