A Pivotal Study to Evaluate the Clinical Benefit, Performance and Safety of a Totally Implantable Cochlear Implant (TICI) System in Adults

Exclusion Criteria19

• Prior cochlear implantation, in either ear, or medical plan for cochlear implantation during the clinical investigation, contralateral to the ear to be implanted.
• Candidates with single-sided deafness as determined by the investigator.
• Intra-axial (within-the-brain) lesions or deafness due to lesions of the acoustic nerve affecting the ear to be implanted.
• Middle ear infection (including acute otitis media, chronic otitis media, suppurative otitis media, or serous drainage) in the ear to be implanted either at the time of surgery or within 3 months prior to enrolment.
• Presence of a tympanic membrane perforation or a history of otologic surgery within 3 months prior to enrolment, in the ear to be implanted.
• Previously reported diagnosis of auditory neuropathy, in the ear to be implanted.
• Ossification, malformation or any other cochlear anomaly, such as common cavity, that might prevent complete insertion of the electrode array, in the ear to be implanted.
• Current cerebrospinal fluid (CSF) shunts or drains, existing perilymph fistula, skull fracture or CSF leaks.
• Severe, or poorer, bilateral sensorineural hearing loss prior to 5 years of age, as reported by the participant.
• Severe, or poorer, sensorineural hearing loss for more than 20 years, as reported by the participant, in the ear to be implanted.
• Medical or psychological conditions that contraindicate general anaesthesia, surgery, or participation in the clinical investigation as determined by the investigator.
• Pre-existing skin condition that could jeopardize wound healing as judged by the investigator e.g., psoriasis, dermatitis, use of corticosteroids, uncontrolled diabetes.
• Unrealistic expectations on the part of the participant, regarding the possible benefits, risks, and limitations inherent to the surgical procedure(s) and prosthetic devices, as determined by the Investigator.
• Additional disabilities that may affect the participant's participation or safety during the clinical investigation.
• Unable or unwilling to comply with all requirements of the clinical investigation, as determined by the investigator.
• Pregnant or breastfeeding women.
• Investigator site personnel directly affiliated with this study and/or their immediate families. Immediate family is defined as spouse, parent, child or sibling.
• Cochlear employees or employees of Contract Research Organisations or contractors engaged by Cochlear for the purposes of the 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).
