So, what about the argument that the 510(k) program stifles innovation? We are excluding innovative business models (i.e., devices that are part product and part ser- vice), innovative marketing (i.e., direct sales to patients), and innovative manufacturing (i.e., molding rather than machining) of med- ical devices. Also, we are not talking about the PMA program, which requires FDA- supervised clinical trials, extensive data analyses by FDA biostatisticians, and de- tailed audits of design and manufacturing processes. That process takes considerable time, but we are obliged to balance that against practitioners and patients getting devices that are reasonably safe and effec- tive. In return, federal preemption shields the manufacturer. When you discuss innovation in the con- text of the 510(k) program, you are refer- ring to technological innovations. Marginal innovations are considered innovations in academic circles, but not by the public. Technological innovation is typically an incremental process, which may decrease cost, increase reliability, and so forth. Mar- ginal innovation is making a clone; it is not a significant improvement. For the 510(k), the issue boils down to figuring out how to do the testing neces- sary to support your claim that there is low or very low uncertainty about establish- ing reasonable safety and effectiveness for the intended use of the device. This often means recognizing what consensus stan- dards and engineering best practices apply to the device. Some are "horizontal" (i.e., electrical safety, biocompatibility, software development, and human factors issues) and some are "vertical" (they only apply to a specific type of device). In other cases, it means recognizing that particular special controls exist; all special controls are verti- cal standards. It can also mean doing a piv- otal clinical trial, because bench testing and animal testing are insufficient.3 To avoid wasting time, it's important to understand both the applicable consensus standards and any special controls and do the required testing. Have a third-party lab- oratory do the testing, or get help from an expert consultant. Conducting testing com- pletely and correctly and then presenting it clearly reduces the changes of delays. Some may say, "Well, that is not my experi- ence." But make sure you are not comparing apples and oranges.
