The United States represents the world's largest consumer market. For medical device products to enter the U.S. market, they must first obtain FDA certification.
I. U.S. Regulatory Authorities
1. U.S. FDA (Food and Drug Administration)
CDRH (Center for Devices and Radiological Health): Responsible for the review and approval of medical devices entering the market. It handles submissions such as Premarket Notifications (510(k)), Premarket Approval (PMA) applications, as well as devices that are not yet approved but intended for use in clinical trials.
CBER (Center for Biologics Evaluation and Research): Oversees the regulation of medical devices related to biological products.
2. Regulatory Framework
- 1976: Food, Drug, and Cosmetic Act (FDCA), Medical Device Amendments
- 1990: Safe Medical Device Act (SMDA)
3. Medical Device Classification and Registration Pathways
Registration Pathway | Applicable Products | Remarks |
Exempt | Most Class I devices, a small portion of Class II devices |
|
510(k) | A small portion of Class I devices, most Class II devices |
|
PMA | A small portion of Class II devices, all Class III devices |
|
De Novo | Novel devices of low to moderate risk without a predicate |
|
HDE | Devices intended for treating rare conditions or life-threatening diseases |
|
EUA | Special pathway for rapid authorization of unapproved devices during public health emergencies (e.g., pandemics, biothreats). |
