  1. The Device Development Process

Step 2: Preclinical Research-Prototype

Researchers build a device prototype, or an early version of a medical device. At this stage, the device prototype is not for human use. Researchers test the prototypes in controlled laboratory settings. Refining the prototype provides researchers with important information about the product’s potential use for people. The prototype process attempts to reduce risk of harm in people. However, it is not possible to eliminate risk entirely.
