First Implantable Cochlear Implant Launches

Med‑El’s TICI Unico is the first commercially available fully implantable cochlear implant, placing the microphone, sound processor, rechargeable battery, and data coil entirely beneath the scalp to deliver continuous, invisible hearing. The 20‑gram system links a nickel‑sized subcutaneous microphone (about 6 mm under the skin) to a postage‑stamp‑sized stimulator that houses processing hardware and a non‑replaceable lithium‑ion battery, plus a coil for recharging and data transfer. A lead connects to a standard electrode array in the cochlea. Users recharge the unit through the scalp with a magnetic GoPod charger; a full 1-1.5 hour charge yields up to 40 hours of use and Med‑El projects at least 24 hours per charge for a minimum of 15 years. Developing a microphone that performs reliably through tissue was the primary engineering hurdle after more than 15 years of work.

Clinical testing and early commercial use show hearing performance comparable to conventional behind‑the‑ear processors while adding benefits such as hearing during sleep, swimming, and activities that previously disrupted external hardware. European regulatory approval has been granted and the first four commercial implantations were performed; the device is not yet available in the United States. Patient reports emphasize increased freedom and safety. Independent researchers applaud the long‑awaited innovation and expect it to spur competition and further advances in cochlear‑implant design.
