»The Medical Device Manufacturer's Obligation to Monitor Products«: The thesis examines the medical device manufacturer's obligation to monitor products (i.e., collecting and evaluating information about products placed on the market and taking corrective action) within the framework of public product safety law and private product liability law. In addition to various specific issues (e.g., the interaction between the MDR, GPSR, and AIA; the scope of the recall obligation), the relationship between public and private product monitoring obligations is analyzed.
