During which phase of the medical device life cycle does market launch occur?

The correct response highlights that market launch occurs during the regulatory approval phase of the medical device life cycle. This phase is crucial as it is when the device has undergone all necessary testing and evaluations to demonstrate its safety and effectiveness. Prior to reaching this stage, the device has gone through the design phase, which involves conceptualization, engineering, and iterative testing. However, these steps alone do not permit market entry.

Once a device successfully completes preclinical testing and obtains regulatory approval, it is then cleared or authorized for sale in the market. This regulatory approval step involves thorough evaluation by relevant authorities—such as the FDA in the United States—where documentation and data on the device’s safety, efficacy, and quality are reviewed. Only upon approval can the device be marketed and sold to consumers and healthcare providers.

After the market launch, the focus shifts to post-market surveillance to monitor the device’s performance in the general population, ensuring continued safety and effectiveness. However, it is important to recognize that market launch specifically happens after receiving regulatory approval, making that phase the pivotal moment for entering the market.
