IEC 62304 is an international standard that defines the life cycle requirements for medical device software. It provides a framework for developing and maintaining software used in medical devices, ensuring safety and effectiveness throughout the software’s life cycle. This standard is recognized by regulatory bodies such as the U.S. Food and Drug Administration (FDA) and the European Union’s Medical Device Regulation (MDR), making compliance essential for market approval in these regions.
IEC 62304 is an international standard that specifies lifecycle requirements for medical device software, including software development, maintenance, and risk management. The standard helps ensure software safety and effectiveness and provides a framework for building reliable software.
- Software Development: It includes planning, design, implementation, and testing.
- Software Maintenance: Covers activities after release, like updates and bug fixes.
- Risk Management: Identifies and mitigates potential software risks.
- Problem Resolution: Outlines how to handle software issues.
- Configuration Management: Manages changes to the software.
IEC 62304 classifies medical device software based on its potential to cause harm. The classification dictates the rigor of the development process, and higher classifications require more stringent controls.
| Classification |
Description |
| Class A |
No injury or damage to health is possible. Software typically manages minor functions or provides information without direct patient impact. |
| Class B |
Non-serious injury is possible. Software performs functions where failure could lead to minor harm or inconvenience, but not life-threatening situations. |
| Class C |
Death or serious injury is possible. Software controls critical functions where failure could result in severe harm, permanent impairment, or death. This class demands the highest level of scrutiny and control. |
Manufacturers and developers of medical device software must comply with IEC 62304. This includes a broad range of entities. Compliance ensures their software meets safety and performance standards.
| Entity |
Description |
| Medical Device Manufacturers |
Any company that develops, produces, or markets medical devices containing software. This includes both hardware and standalone software. |
| Software Developers for Medical Devices |
Companies or individuals specifically creating software components for integration into medical devices. This can include operating systems, application software, or embedded software. |
| Companies Developing Standalone Medical Software |
Applications such as mobile medical apps, health information systems, or diagnostic software that operates independently of a physical medical device but still falls under medical device regulations. |
| Original Equipment Manufacturers (OEMs) |
Companies that provide software components or modules to other medical device manufacturers. They must ensure their supplied software meets the standard’s requirements. |
| Contract Research Organizations (CROs) |
If CROs are involved in developing or testing software for medical devices as part of their services, they need to be aware of and adhere to IEC 62304 principles. |
