Regulation of Medical Devices in the United States and European Union

Abstract
Millions of patients worldwide depend on an ever-widening array of medical devices for the diagnosis and management of disease. In the United States, the Food and Drug Administration (FDA) requires manufacturers of high-risk devices such as heart valves and intraocular lens implants to demonstrate safety and effectiveness before the devices can be marketed. However, some policymakers and device manufacturers have characterized U.S. device regulation as slow, risk-averse, and expensive.1,2 Other experts, such as those at the Institute of Medicine, have suggested that current premarketing procedures may not be comprehensive enough and may be particularly dangerous for devices that have been cleared by the FDA on the basis of substantial similarity to an already marketed device.3
