14. ISO 13485, Medical Device Quality Management & Regulatory Compliance

Medical-device quality management combines organizational processes, product controls, risk management, and regulatory requirements to ensure that devices consistently meet their intended safety and performance requirements. This topic explains ISO 13485, its current edition and relationship with FDA’s 2026 Quality Management System Regulation, along with differences from ISO 9001 and the additional obligations imposed by 21 CFR Part 820. It also covers common implementation mistakes, quality-management principles, ISO-standard categories, and the lifecycle requirements for medical-device regulatory compliance. Certification can support regulatory readiness and customer confidence, but it does not replace product authorization, jurisdiction-specific compliance, or continuing post-market responsibilities.
