The document examines and compares the medical device regulatory systems of 18 Latin American countries, finding that while most have implemented premarket controls like risk-based classification and approval processes, postmarket controls vary and some countries have no formal regulatory programs. Key differences between countries include the maturity and transparency of regulations, use of risk-based classification, review timelines, and extent of postmarket controls like adverse event reporting and device tracking. Overall regulatory systems in the region are still evolving, with some driven by trade agreements and others described as static or opaque.
