The purpose of this document is to provide guidance to the sponsors of premarket notifications [510(k)s] for restorative devices. This document is intended to assist the sponsors in organizing and providing the essential information that should be submitted to the Food and Drug Administration (FDA) for review.
This guidance is based on the Restorative Devices Branch's (REDB's) identification of specific criteria necessary to conduct an adequate evaluation of a 510(k) for the purpose of determining substantial equivalence for physical medicine/restorative devices. The objective of this document is to delineate to the device manufacturer important administrative, descriptive, and scientific information that should be included in a 510(k) for a restorative device. Individual 510(k) submissions may require additional information pertinent to each specific device. The suggestions and recommendations included in the guidance reflect the minimal requirements that would allow an evaluation of the device as determined by REDB. While the use of this document in the preparation of a 510(k) premarket notification will not ensure FDA clearance of a device, following the guidance will ensure that sufficient basic information is available to initiate a substantive review.
Note that the guidance document is a living document. It will be periodically revised as scientific knowledge and regulations change.
Any 510(k) notification submitted under premarket notification procedures described in 21 Code of Federal Regulations (CFR) Part 807, Subpart E, for FDA's determination that a new device is substantially equivalent to a predicate (existing) device in 21 CFR 890.1385 (Diagnostic electromyograph needle electrode) should follow the format below and must contain all specified information that is applicable to the device.
- Provide the name, address, phone and fax number of the manufacturer and sponsor of the 510(k) submission.
- Provide the FDA registration number (if available) of the manufacturer of the new device.
- Identify the official contact person for all correspondence.
As stated in 21 CFR 807.90(d), a 510(k) shall be submitted separately for each product the manufacturer intends to market. However, a 510(k) submission may include more than one item as in the case of a device that is available in a range of sizes or if the 510(k) is submitted for a kit.
A submission can describe more than one component of, or attachment to, a single device. The submission must compare each such component or attachment with that of a predicate device, or must state that the predicate device lacks such a component or attachment.
The following information must be provided:
- The proprietary name of the new device;
- The generic name of the device;
- The classification of the predicate device e.g., Class II. Refer to 21 CFR and section 513 of the Food, Drug, and Cosmetic Act;
- The proposed regulatory class for the new device, e.g., Class II. (21 CFR 862-892 contains the regulatory classifications for medical devices); and
- The panel code(s) for the device. [If the product is not classified under the physical medicine devices panel, identify the panel under which it is classified and provide the panel identification code (e.g., 89 is the code for the physical medicine devices panel)].
Specify whether this device:
- Has been previously submitted to the FDA for identical or different indications;
- Is currently being reviewed for different indications by the same or different branch within ODE; or
- Has been previously cleared by the FDA for different indications.
DEVICE DESCRIPTIVE INFORMATION
Identify the specific intended use(s) for the subject device and the predicate device. The new device must have the same intended medical uses as those specified for the predicate device, to the extent that the changes do not alter the therapeutic or diagnostic effect and do not affect safety and effectiveness. These intended uses must be consistent with the descriptions of intended medical uses contained within the CFR section that is applicable to the device and must identify the specific medical conditions for which the device is indicated. If the indication differs, you must provide a justification as to how the change(s) do not affect safety and effectiveness. If special labeling claims are sought, information must be provided to support these claims.
It is not necessary to notify FDA of an intent to market a device if it will not be labeled or promoted for medical uses. However, FDA will regulate the equipment and may require premarket notification if any promotional material appears which makes medical claims after marketing begins.
- Provide a written description of the device, including all device components, instruments, and any new features of the device.
- Identify the relevant dimensions of the device and all possible configurations, describing the function of each component.
- Describe how the device works and interconnects with other components.
- Provide photographs or other illustrations, such as dimensioned drawings, showing front, rear, and side views of the device.
Identify the materials for each component (i.e., the specific kind and grade of metal used), the voluntary standards with which the device materials will conform or will be compared, and describe any additional processing that may affect the material properties.
Provide the chemical composition of all materials used to construct the electrode. The materials used must be compatible with all manufacturing processes including sterilization.
- Provide draft or sample package labeling and package inserts for the new device (see 21 CFR 801).
- Provide a prescription legend (21 CFR 801.109) which reads:
"Caution: Federal Law restricts this device to sale by or on the order of a practitioner licensed by the law of the State in which he/she practices."
- Identify whether the electrode is monopolar or bipolar.
- Specify the range of sizes.
- Provide sterilization information.
- Include a statement that the electrode is "nonpyrogenic" and a description of the pyrogen testing method.
- Identify the models of the cables to be used with the electrode. Please note that electrode cables are exempt devices and should not be included as part of a 510(k) application for electrodes.
SUBSTANTIAL EQUIVALENCE INFORMATION
The legally marketed predicate device with which the subject device is to be compared for the determination of substantial equivalence must be identified. Evidence must be provided that the device was placed into interstate commerce for other than research uses or as part of a plant-to-plant transfer and was actually labeled and promoted for the intended use to which the submitter of the premarket notification is claiming substantial equivalence. This may be accomplished by providing copies of the firm's advertisements, catalog pages, or other promotional material dated prior to May 28, 1976 and shipping documents such as invoices, bills of lading, receipts showing the interstate transit of the device (for other information which can be used to prove Pre-Amendment status contact DSMA).
Alternatively, the 510(k) number(s) of the predicate device(s) may be identified. The 510(k) number may be obtained from the Electronic Docket (ED), an automated retrieval system of the Division of Small Manufacturers Assistance (DSMA), which provides medical device regulations, FDA talk papers and press releases, device evaluation guidance, and the listing of all approved 510(k)s sorted by applicant name. This 510(k) information is located under the Product Clearance Main Menu Item # 12. Dial (301) 594-4802 or (800) 252-1366. For more guidance on how to assess this information, contact DSMA. Call toll free (800) 638-2041, (301) 443-6597, or fax (301) 443-8818.
- The submission should include a description of all significant similarities and differences between the new and predicate devices. To facilitate review, the submission should contain a summary which compares the two devices in terms of the intended medical uses, functions and physical characteristics, including safety characteristics.
510(K) SUMMARY OR STATEMENT
- Provide a 510(k) summary of safety and effectiveness information in the premarket notification submission upon which an equivalence determination could be based, written in accordance with the content and format requirements that are specified in 21 CFR 807.92, or
- Provide a 510(k) statement that safety and effectiveness information will be made available to interested persons upon request. This statement must follow the format and contain the wording as specified in 21 CFR 807.93.
TRUTHFUL AND ACCURATE STATEMENT
Provide a statement that all data and information submitted in the premarket notification are truthful and accurate and that no material fact has been omitted, as required by 21 CFR 807.87(j).
