Which medical device would NOT be reviewed by CDRH's Office of Device Evaluation under 510(k) Premarket Notifications?

The correct choice highlights that the blood specimen collection device is not reviewed by the CDRH's Office of Device Evaluation under the 510(k) Premarket Notification process. This is primarily because blood specimen collection devices are typically classified as laboratory devices and come under the purview of the Center for Devices and Radiological Health (CDRH) but may also be regulated by the Center for Biologics Evaluation and Research (CBER). Since they are often considered in the realm of laboratory-developed tests or biological products rather than traditional medical devices, they may not require a 510(k) submission in the same manner as other devices.

High flux hemodialyzers, piston syringes, and cardiopulmonary bypass blood tubing are all examples of devices that fall squarely within the conventional medical device categories requiring rigorous evaluation to ensure safety and effectiveness, making them more likely candidates for review under 510(k). These devices are typically longer-established in clinical environments where regulatory oversight is crucial for patient safety and efficacy in clinical applications. Thus, the distinction in how blood specimen collection devices are categorized compared to conventional medical devices under CDRH regulations accounts for why they would not be reviewed under the 510(k) process.
