A Study to Explore Improved Features and a Simplified Treatment Approach for a Totally Implantable Cochlear Implant (TICI) Research System in Adults With Severe Hearing Loss

Exclusion Criteria

• •Severe, or poorer, bilateral sensorineural hearing loss prior to five years of age, as reported by the subject
• •Duration of severe to profound hearing loss greater than 20 years in the ear to be implanted as reported by the subject or by audiometric history, if available
• •Ossification, otosclerosis, malformation or any other cochlear anomaly, such as common cavity, that might prevent complete insertion of the electrode array
• •Deafness due to lesions of the acoustic nerve affecting the ear to be implanted
• •Medical or psychological conditions that would contraindicate undergoing anaesthesia, surgery or participation in the clinical investigation, as determined by the investigator
• •Additional disabilities that may affect the subject's participation or safety during the clinical investigation, as determined by the investigator
• •Unrealistic expectations on the part of the subject regarding the possible benefits, risks and limitations that are inherent to the surgical procedure and prosthetic device, as determined by the investigator
• •Desire to use an integrated acoustic component post-implantation
• •Unable or unwilling to comply with the requirements of the clinical investigation as determined by the Investigator
• •Investigator site personnel directly affiliated with this study and/or their immediate families; immediate family is defined as a spouse, parent, child, or sibling
• •Cochlear employees or employees of Contract Research Organizations or contractors engaged by Cochlear for the purposes of this investigation.
• •Current participation, or participation in another interventional clinical study/trial in the past 30 days, involving an investigational drug or device (unless Cochlear sponsored and determined by investigator or Sponsor to not impact this investigation)
