Failure to comply with these requirements can result in regulatory actions, which can include recalls, fines, and injunctions.

Class II Medical Devices

Characteristics of Class II Devices

Class II devices present moderate to high risk and require greater regulatory control to ensure safety and effectiveness. Examples include catheters, contact lenses, and surgical gloves. These devices are subject to general and special controls, including specific labeling requirements, performance standards, and post-market surveillance. The FDA requires manufacturers to submit a premarket notification (510(k)) to demonstrate that the device is substantially equivalent to a legally marketed device.

The FDA determines specific special controls for Class II devices based on the type and intended use. These controls may include performance standards, post-market surveillance, patient registries, and specific labeling requirements to mitigate risks. Special controls are designed to address specific risks associated with the device and ensure its safety and effectiveness. For example, a Class II infusion pump may require special controls such as software validation, electromagnetic compatibility testing, and biocompatibility assessments.

Compliance and Safety Measures for Class II Devices

Meeting the FDA’s performance standards for Class II devices can be challenging, particularly for new market entrants.
