Cochlear Implant FDA Regulation, Candidacy Criteria, and Clinical Team Roles

Flashcards covering FDA regulatory device classes, manufacturer-specific candidacy criteria for pediatric and adult cochlear implantation, medical contraindications, and multidisciplinary team roles.

Food and Drug Administration (FDA)

An agency within the Department of Health and Human Services that regulates food, drugs, and medical devices through seven specialized centers.

Center for Devices and Radiological Health

The specific center under the FDA responsible for regulating hearing aids and cochlear implants.

Class 1 Devices

The FDA regulatory category presenting the least safety risk, which includes bandaids, latex gloves, otoscopes, and hearing aids.

Class 2 Devices

The FDA regulatory category presenting moderate safety risk, including bone-anchored hearing systems, catheters, and wheelchairs.

Class 3 Devices

The FDA regulatory category presenting the highest safety risk for devices that support life or prevent impairment, including cochlear implants, auditory brainstem implants, pacemakers, and heart valves.

Premarket Approval (PMA)

The mandatory review process Class 3 devices must undergo, serving as the FDA criteria for whether a patient can be implanted.

Investigational Device Exemption (IDE) Study

A study required prior to PMA that provides device evidence, simulations, research, animal studies, and international human trials before clinical trials can proceed.

Medical Device Reports (MDRs)

Submissions made to the FDA by implanting physicians, audiologists, and patients to report device flaws, performance data, or adverse events post-market.

CI Device Approval Cost

The estimated expense of $595,424$ required each time to get a single cochlear implant device approved by the FDA.

Off-Label Implantation

Implantation that does not strictly align with FDA criteria for a manufacturer or device, requiring supporting clinical evidence for execution.

Advanced Bionics Pediatric Candidacy

Criteria for children (12 months to 17 years, 11 months) with bilateral profound SNHL and limited hearing aid benefit ($\le 20\%$ on MLNT at $70\,\text{dB SPL}$ for ages $\le 4$; $\le 12\%$ on PBK-50 or $< 30\%$ on HINT-C at $70\,\text{dB SPL}$ for ages $\ge 4$).

Advanced Bionics Adult Candidacy

Criteria for adults ($\ge 18$ years) with bilateral post-lingual severe to profound SNHL ($\le 70\,\text{dB}$) and limited HA benefit defined as $\le 50\%$ on the HINT test.

Cochlear Infant/Toddler Candidacy

Criteria for children ages 9 to 24 months with bilateral profound SNHL and documented lack of auditory skill progress on ESP/MAIS following 3 to 6 months of amplification and rehab.

Cochlear Older Pediatric Candidacy

Criteria for children ages 24 months to 17 years, 11 months with bilateral severe to profound SNHL and speech perception sentence testing $\le 30\%$ in the best aided condition ($\le 30\%$ on MLNT for 25m–4y11m; $\le 30\%$ on LNT for 5y–17y11m).

Cochlear Adult Candidacy

Criteria for adults ($\ge 18$ years) with bilateral moderate to profound SNHL scoring $\le 50\%$ in the ear to be implanted and $60\%$ in the best aided binaural condition using AZBio or HINT.

MED-EL Pediatric Candidacy

Criteria for children ages 2 to 17 years, 11 months with bilateral profound SNHL showing lack of auditory progress (younger) or $\le 20\%$ on MLNT/LNT (older) after a 3 to 6 month trial with binaural hearing aids.

MED-EL Adult Candidacy

Criteria for adults ($\ge 18$ years) with bilateral severe to profound SNHL ($\ge 70\,\text{dB}$ PTA at 500, 1000, and 2000 Hz) and $\le 40\%$ in the best aided condition on recorded HINT test.

Medicare

A primarily federally funded health insurance program for adults.

Medicaid

A state-funded health insurance program primarily for children and adults with disabilities.

CMS

Center for Medicare and Medicaid Services.

Meningitis (CI Consideration)

An off-label reason for implantation requiring prompt surgical action before significant intracochlear ossification or fibrosis hardens.

CI Audiologist Role

Team member who performs complete hearing evaluations, assesses hearing aid fit and function, and conducts speech perception testing.

CI Surgeon Role

Team member who evaluates anatomical candidacy via CT scan, checks for medical contraindications, and evaluates realistic expectations.

CI Speech-Language Pathologist Role

Team member who assesses communication abilities, evaluates current habilitation programs, and coordinates ongoing habilitation with service providers.

CI Deaf Educator Role

Team member who educates families on CI mechanics, emphasizes family effort requirements, highlights rehabilitation importance, and sets realistic expectations.

CI Social Worker Role

Team member who identifies family roadblocks such as transportation, family support systems, and expectations.

CI Psychologist Role

Team member responsible for assessing suspected cognitive or psychological issues in candidates prior to implantation.
