ClinConnect Summary

This clinical trial is testing a new device called the Mi2000 Totally Implantable Cochlear Implant, aimed at helping people with severe hearing loss understand speech better. The main goal is to see if this implant can improve how well participants can hear and understand words and sentences compared to their hearing ability before the surgery.

To be eligible for this trial, participants need to be at least 18 years old and have significant hearing loss that hasn't improved with hearing aids. They should also have a functional auditory nerve and realistic expectations about the benefits of the implant. During the trial, participants will receive the implant and undergo several hearing tests both before and after the procedure to measure any improvements. It’s important for participants to be committed to follow-up visits for adjustments and support after getting the implant.

• • External or middle ear infections are present
• • The tympanic membrane is perforated in the ear to be implanted
• • Anatomic abnormalities are present that would prevent appropriate placement of the stimulator housing in the bone of the skull, or prevent placement of the chosen electrode array into the cochlea (including ossification of the cochlea)
