- (a) Identification. A powered insertion system for a cochlear implant electrode array is a prescription device used to assist in placing an electrode array into the cochlea.
(b) Classification. Class II (special controls). The special controls for this device are:
- (1) Clinical performance testing must demonstrate that the device performs as intended under anticipated conditions of use, including evaluation of all adverse events.
(2) Non-clinical performance testing must demonstrate that the device performs as intended under anticipated conditions of use. Testing must include:
- (i) Verification of cochlear implant attachment force, release force, and insertion speed;
- (ii) Testing to demonstrate the device does not damage or degrade the cochlear implant (including the lead and array portions of the cochlear implant); and
(iii) Comparison testing with manual insertion to evaluate:
- (A) Differences in cochlear implant array insertion force associated with use of the device; and
- (B) Intracochlear placement of the cochlear implant array (intended scala placement and array insertion depth, together with minimal array tip foldover and cochlear scala translocation).
(3) Usability testing in a simulated hospital environment with an anatomically relevant model (e.g., cadaver testing) that evaluates the following:
- (i) Successful use to aid in placement of the electrode array into the cochlea; and
- (ii) Harms caused by use errors observed.
- (4) Changes in cochlear implant compatibility are determined to significantly affect the safety or effectiveness of the device and must be validated through performance testing or a rationale for omission of any testing.
- (5) The patient-contacting components of the device must be demonstrated to be biocompatible.
- (6) Performance testing must demonstrate the electromagnetic compatibility, electrical safety, and thermal safety of the device.
- (7) The patient-contacting components of the device must be demonstrated to be sterile and non-pyrogenic.
- (8) Performance testing must support the shelf life of device components provided sterile by demonstrating continued sterility, package integrity, and device functionality over the labeled shelf life.
- (9) Software verification, validation, and hazard analysis must be performed for any software components of the device.
(10) Labeling must include:
- (i) The recommended training for the safe use of the device;
- (ii) Summary of the relevant clinical and non-clinical testing pertinent to use of the device with compatible electrode arrays; and
- (iii) A shelf life.
