7.2.1 Device Classification 778 The Medical Device Amendments (MDA) (Pub. L. 94-295) to the Federal FD&C Act (enacted in 779 1976) directed FDA to issue regulations that classify all devices that were in commercial 780 distribution at that time into one of three regulatory control categories: Class I, II, or III, 781 depending upon the degree of regulation necessary to provide reasonable assurance of their 782 safety and effectiveness. The class into which a device is placed determines the requirements that 783 a medical device manufacturer must meet prior to distributing a device in interstate commerce. 784 According to section 513(a)(1) of the FD&C Act (21 U.S.C. § 360c(a)(1)), the following are 785 defined as the device classes:

786 787

( a ) Class I .—Devices are subject to a comprehensive set of regulatory authorities called

general controls that are applicable to all classes of devices.

( b ) Class II .—Devices for which general controls, by themselves, are insufficient to provide 790 reasonable assurance of the safety and effectiveness of the device, but for which there is 791 sufficient information to establish special controls to provide such assurance. 792 ( c ) Class III .—Device for which general controls, by themselves, are insufficient and for 793 which there is insufficient information to establish special controls to provide reasonable 794 assurance of the safety and effectiveness of the device. Class III devices typically require 795 premarket approval.
