Glossary Term
IEC 62304
Definition
IEC 62304 is an international standard that outlines the life cycle requirements for the development of medical device software. It provides a framework for establishing processes to ensure the safety and effectiveness of software throughout its life cycle, from initial development through maintenance and retirement. The standard defines the activities, tasks, and documentation necessary for each stage of the software development process, including software planning, design, implementation, verification, validation, and maintenance. IEC 62304 is intended to help manufacturers of medical device software comply with regulatory requirements and demonstrate that their software is safe for use in medical devices.
Relevance to the MedTech Industry
IEC 62304 is critical for ensuring that medical device software meets safety and regulatory requirements. As medical devices increasingly rely on software to control functionality or deliver healthcare solutions (e.g., infusion pumps, diagnostic equipment, imaging systems), ensuring the software’s safety, reliability, and compliance with international standards becomes paramount. Regulatory agencies such as the FDA and EMA require compliance with IEC 62304 to demonstrate that the software in medical devices has been developed using a risk-based approach and follows best practices in software engineering. Compliance with IEC 62304 helps prevent software-related failures and ensures that the medical device functions as intended to safeguard patient health.

Key Features of IEC 62304 in MedTech
Software Life Cycle Processes: IEC 62304 establishes a set of required software life cycle processes, which include software development, risk management, configuration management, software maintenance, and software retirement. The standard emphasizes the importance of structured planning, testing, and validation at each stage.
Risk Management: The standard places a strong focus on software risk management, requiring that risks associated with software failures be identified, assessed, mitigated, and controlled throughout the software development lifecycle. This includes performing a risk analysis to evaluate the potential hazards that could arise from software failures.
Verification and Validation: IEC 62304 requires that software undergo verification (to confirm that the software was built correctly according to specifications) and validation (to confirm that the software meets the intended use and safety requirements). Both processes must be documented thoroughly to ensure compliance.
Software Configuration Management: The standard mandates that software development and version control be properly managed. Software configuration management ensures that all versions of software, including code, documentation, and test results, are well-organized and tracked.
Software Maintenance and Updates: IEC 62304 outlines the process for maintaining medical device software after its release, ensuring that any software updates, patches, or bug fixes are evaluated and validated to prevent introducing new risks or safety concerns.
