Pathway characteristics

NIX Device Classification - Class 2, Special Controls

Product Code NIX Hearing Aid, Air Conduction, Transcutaneous System
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 874.3950
Definition The Transcutaneous Air Conduction Hearing Aid System Is A Wearable Sound-amplifying Device That Is Intended To Compensate For Impaired Hearing. It Consists Of An Air Conduction Hearing Aid Attached To A Surgically Fitted Tube System. The Tube Creates An Air Channel Through The Soft Tissue Between Outer Ear Canal And The Post-auricular Region Of The Pinna (ear). The Air Conduction Hearing Aid Attaches To The Post-auricular Opening Of The Tube, Thereby Transmiting Amplified Sound To The Ear Canal Without Occluding The Canal.
What this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. This pathway does not require clinical trials - it relies on engineering equivalence and performance data. Most Ear, Nose, Throat devices follow this clearance model.
