As everyone already answered the initial question in full detail. I would like to add why I believe it is important to have post market surveillance. Yes it gives companies feedback and how to better future products or if a defect is detected, then how to recover. But data collected during this surveillance is what matters and how that data is shared is critical. Sharing of such surveillance can be an issue with different competitors for money reason. So to point out that this can be looked at from a different point of view. The data and sharing of this data in a timely manner is critical for future medical devices or similar products or adding another extension or function to the current product on the market.
