[Federal Register Volume 84, Number 208 (Monday, October 28, 2019)] [Rules and Regulations] [Pages 57610-57612] From the Federal Register Online via the Government Publishing Office [www.gpo.gov] [FR Doc No: 2019-23464] ----------------------------------------------------------------------- DEPARTMENT OF HEALTH AND HUMAN SERVICES Food and Drug Administration 21 CFR Part 874 [Docket No. FDA-2019-N-4328] Medical Devices; Ear, Nose, and Throat Devices; Classification of the Self-Fitting Air-Conduction Hearing Aid AGENCY: Food and Drug Administration, HHS. ACTION: Final order. ----------------------------------------------------------------------- SUMMARY: The Food and Drug Administration (FDA or we) is classifying the self-fitting air-conduction hearing aid into class II (special controls). The special controls that apply to the device type are identified in this order and will be part of the codified language for the self-fitting air-conduction hearing aid's classification. We are taking this action because we have determined that classifying the device into class II (special controls) will provide a reasonable assurance of safety and effectiveness of the device. We believe this action will also enhance patients' access to beneficial innovative devices, in part by reducing regulatory burdens. DATES: This order is effective October 28, 2019. The classification was applicable on October 5, 2018.

SUPPLEMENTARY INFORMATION: I. Background Upon request, FDA has classified the self-fitting air-conduction hearing aid as class II (special controls), which we have determined will provide a reasonable assurance of safety and effectiveness. In addition, we believe this action will enhance patients' access to beneficial innovation, in part by reducing regulatory burdens by placing the device into a lower device class than the automatic class III assignment. The automatic assignment of class III occurs by operation of law and without any action by FDA, regardless of the level of risk posed by the new device. Any device that was not in commercial distribution before May 28, 1976, is automatically classified as, and remains within, class III and requires premarket approval unless and until FDA takes an action to classify or reclassify the device (see 21 U.S.C. 360c(f)(1)). We refer to these devices as ``postamendments devices'' because they were not in commercial distribution prior to the date of enactment of the Medical Device Amendments of 1976, which amended the Federal Food, Drug, and Cosmetic Act (FD&C Act). FDA may take a variety of actions in appropriate circumstances to classify or reclassify a device into class I or II. We may issue an order finding a new device to be substantially equivalent under section 513(i) of the FD&C Act to a predicate device that does not require premarket approval (see 21 U.S.C. 360c(i)). We determine whether a new device is substantially equivalent to a predicate by means of the procedures for premarket notification under section 510(k) of the FD&C Act (21 U.S.C. 360(k)) and part 807 (21 CFR part 807). FDA may also classify a device through ``De Novo'' classification, a common name for the process authorized under section 513(f)(2) of the FD&C Act (21 U.S.C. 360c(f)(2)). Section 207 of the Food and Drug Administration Modernization Act of 1997 established the first procedure for De Novo classification (Pub. L. 105-115). Section 607 of the Food and Drug Administration Safety and Innovation Act modified the De Novo application process by adding a second procedure (Pub. L. 112- 144). A device sponsor may utilize either procedure for De Novo classification. Under the first procedure, the person submits a 510(k) for a device that has not previously been classified. After receiving an order from FDA classifying the device into class III under section 513(f)(1) of the FD&C Act, the person then requests a classification under section 513(f)(2). Under the second procedure, rather than first submitting a 510(k) and then a request for classification, if the person determines that there is no legally marketed device upon which to base a [[Page 57611]] determination of substantial equivalence, that person requests a classification under section 513(f)(2) of the FD&C Act. Under either procedure for De Novo classification, FDA is required to classify the device by written order within 120 days. The classification will be according to the criteria under section 513(a)(1) of the FD&C Act. Although the device was automatically within class III, the De Novo classification is considered to be the initial classification of the device. We believe this De Novo classification will enhance patients' access to beneficial innovation, in part by reducing regulatory burdens. When FDA classifies a device into class I or II via the De Novo process, the device can serve as a predicate for future devices of that type, including for 510(k)s (see 21 U.S.C. 360c(f)(2)(B)(i)). As a result, other device sponsors do not have to submit a De Novo request or premarket approval application in order to market a substantially equivalent device (see 21 U.S.C. 360c(i), defining ``substantial equivalence''). Instead, sponsors can use the 510(k) process, when necessary, to market their device. II. De Novo Classification On May 11, 2018, Bose Corp. submitted a request for De Novo classification of the Bose Hearing Aid. FDA reviewed the request in order to classify the device under the criteria for classification set forth in section 513(a)(1) of the FD&C Act. We classify devices into class II if general controls by themselves are insufficient to provide reasonable assurance of safety and effectiveness, but there is sufficient information to establish special controls that, in combination with the general controls, provide reasonable assurance of the safety and effectiveness of the device for its intended use (see 21 U.S.C. 360c(a)(1)(B)). After review of the information submitted in the request, we determined that the device can be classified into class II with the establishment of special controls. FDA has determined that these special controls, in addition to the general controls, will provide reasonable assurance of the safety and effectiveness of the device. Therefore, on October 5, 2018, FDA issued an order to the requester classifying the device into class II. FDA is codifying the classification of the device by adding 21 CFR 874.3325. We have named the generic type of device self-fitting air-conduction hearing aid, and it is identified as a wearable sound amplifying device that is intended to compensate for impaired hearing and incorporates technology, including software, that allows users to program their hearing aids. This technology integrates user input with a self-fitting strategy and enables users to independently derive and customize their hearing aid fitting and settings. FDA has identified the following risks to health associated specifically with this type of device and the measures required to mitigate these risks in table 1. Table 1--Self-Fitting Air-Conduction Hearing Aid Risks and Mitigation Measures ------------------------------------------------------------------------ Identified risks Mitigation measures ------------------------------------------------------------------------ Diminished hearing due to over- Software verification, amplification caused by: validation, and hazardExcessively high sound output analysis; levels in the ear canal Electroacoustic performance Device malfunction testing; and Interference with or from other Electromagnetic devices compatibility (EMC) testing.

Excessively long ear piece Device malfunction Use error Missed or delayed medical diagnosis or Labeling. treatment due to failure to self-identify correct population and condition ------------------------------------------------------------------------ FDA has determined that special controls, in combination with the general controls, address these risks to health and provide reasonable assurance of safety and effectiveness. In order for a device to fall within this classification, and thus avoid automatic classification in class III, it would have to comply with the special controls named in this final order. The necessary special controls appear in the regulation codified by this order. This device is subject to premarket notification requirements under section 510(k) of the FD&C Act. III. Analysis of Environmental Impact The Agency has determined under 21 CFR 25.34(b) that this action is of a type that does not individually or cumulatively have a significant effect on the human environment. Therefore, neither an environmental assessment nor an environmental impact statement is required. IV. Paperwork Reduction Act of 1995 This final order establishes special controls that refer to previously approved collections of information found in other FDA regulations and guidance. These collections of information are subject to review by the Office of Management and Budget (OMB) under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). The collections of information in the guidance document ``De Novo Classification Process (Evaluation of Automatic Class III Designation)'' have been approved under OMB control number 0910-0844; the collections of information in 21 CFR part 820, regarding quality system regulation, have been approved under OMB control number 0910-0073; the collections of information in 21 CFR part 814, subparts A through E, regarding [[Page 57612]] premarket approval, have been approved under OMB control number 0910- 0231; the collections of information in part 807, subpart E, regarding premarket notification submissions, have been approved under OMB control number 0910-0120; and the collections of information in 21 CFR part 801, regarding labeling, have been approved under OMB control number 0910-0485. List of Subjects in 21 CFR Part 874 Medical devices. Therefore, under the Federal Food, Drug, and Cosmetic Act and under authority delegated to the Commissioner of Food and Drugs, 21 CFR part 874 is amended as follows: PART 874--EAR, NOSE, AND THROAT DEVICES 0 1.
