Medical Device Regulation (MDR) is the legal framework for bringing medical devices to market. In the EU, MDR (Medical Device Regulation) replaced the Medical Device Directive. In the US, FDA (Food and Drug Administration) regulates devices. Both require: device classification (risk level), clinical/technical evidence, quality management system (QMS), post-market surveillance, and reporting adverse events. Compliance means devices are safe and effective; non-compliance means legal liability, product recalls, fines. Medical device companies need regulatory expertise to avoid catastrophic mistakes. Misclassifying a device costs millions (design rework, delayed launch, legal liability). Regulatory experts prevent these disasters. They're also bottlenecks: scarce, high-demand, well-paid. Learning MDR positions you to lead compliance strategy for device companies or become an independent regulatory consultant.
