Which statement best describes Class II medical devices?

• A. Must prove safety and effectiveness in humans
• B. To meet specific performance standards; examples include tampons, heating pads, syringes
• C. Require full PMA before marketing
• D. Are exempt from regulation

Answer: (B)

Class II devices are regulated with general controls plus additional, device-specific safeguards called special controls. The emphasis is on meeting defined performance standards that ensure the device works as intended and can be used safely in its normal setting. Because of their moderate risk, these devices typically go through a 510(k) premarket process, where the manufacturer must show substantial equivalence to a legally marketed predicate device, rather than conducting new human clinical trials to prove safety and effectiveness. That’s why describing them as needing to meet specific performance standards best captures how they are regulated. The examples given—tampons, heating pads, syringes—illustrate items that require defined performance criteria and appropriate controls, rather than the full, high-level demonstration of effectiveness in humans demanded for high-risk devices. They are not exempt from regulation, and full PMA is not usually required for Class II.
