Understanding MDR: Impacts on Medical Device Development

The European Union's Medical Device Regulation (MDR), formally known as Regulation (EU) 2017/745, represents a significant shift in how medical devices are designed, developed, and brought to market. Implemented to enhance patient safety and improve product efficacy, the MDR enforces stricter oversight throughout the product lifecycle, from initial concept to post-market surveillance.

For professionals in the medical electronics industry—designers, engineers, and product developers—adapting to these new requirements is essential for maintaining compliance and achieving seamless innovation. Among the most pressing challenges they must face is the requirement for comprehensive design data management. Under MDR, every aspect of a device's development must be meticulously documented, ensuring traceability, transparency, and accountability. 

Join us as we explore the practical implications of MDR compliance and, more specifically, how these new regulation requirements impact version control, revision history, cloud-based collaboration, and requirements traceability. We also examine how Altium 365 helps teams meet regulatory demands while maintaining efficiency and collaboration, the drivers of sustainable innovation.

Enhanced Documentation and Technical File Requirements

Under the MDR, maintaining comprehensive technical documentation is not just recommended. It is a core requirement. Manufacturers must compile detailed technical files demonstrating regulatory compliance, including:

• Device specifications and intended purpose
• Manufacturing processes and quality control measures
• Risk assessments and mitigation strategies
• Clinical evaluations to validate safety and performance

For engineers and designers, this means tracking every stage of development to ensure that all decisions are supported by clear, documented justifications.

Traditional design file management methods, such as local storage or disconnected systems, can create inconsistencies, hinder timely access, and introduce compliance risks. Instead, teams need digital solutions that provide structured, real-time access to up-to-date design data.

As MDR requires significantly more detailed documentation than previous regulatory frameworks, design teams must integrate documentation efforts into their workflows from the start. Adopting tools that automate documentation, such as Altium 365’s structured approach to versioning and file management, reduces administrative overhead while improving compliance readiness.

Version Control and Revision History: Ensuring Traceability

One of the most critical aspects of MDR compliance is traceability, which requires a transparent history of all design changes. Every revision of a medical device design must be logged, including:

• What changes were made
• Who made them
• Why they were made
• When they occurred

Without a well-structured version control system, tracking these elements can become an arduous task. Manual tracking methods, such as spreadsheets or email chains, are highly prone to human error and can introduce inconsistencies, resulting in unreliable data that is difficult to access and trace, creating a bottleneck in the compliance process.

Altium 365’s version control capabilities provide a structured system for tracking modifications, preventing uncontrolled changes. Engineers can automatically document design changes, reducing the risk of discrepancies and making it easier to demonstrate compliance during audits.

Stringent version control ensures that obsolete designs are not mistakenly used in production, which could lead to compliance violations or costly recalls. By maintaining an organized revision history, teams can ensure that only approved, up-to-date designs are used, while outdated versions remain archived but accessible for reference. Access controls and approval workflows further safeguard against unintended modifications. 

Additionally, version control allows teams to revert to previous iterations quickly if issues arise, enabling efficient troubleshooting and design updates. Previous versions of a design can also be used to construct documentation for an audit trail, engineers can easily track modifications, demonstrate compliance, and address regulatory concerns with confidence.

Cloud-Based Collaboration: Secure and Compliant Design Management

MDR compliance requires seamless collaboration among designers, regulatory specialists, and quality assurance teams. At the same time, security remains paramount, as medical device data contains highly sensitive intellectual property and regulatory information.

By addressing both security and collaboration needs, Altium 365 streamlines compliance while fostering innovation, facilitating secure, cloud-based collaboration, and allowing teams to:

• Access a centralized repository for real-time updates.
• Enable regulatory and quality teams to securely access controlled design versions.
• Implement role-based access controls, restricting unauthorized modifications.
• Utilize end-to-end encryption to protect sensitive design data.

Cloud-based design management ensures all stakeholders work from a single source of truth, minimizing errors and accelerating approval cycles.

Furthermore, by leveraging cloud collaboration, organizations eliminate information silos, ensuring seamless communication between design teams, regulatory consultants, and auditors. Instead of clunkily exchanging files, authorized users can instantly access the latest design versions, reducing miscommunication and ensuring the uninterrupted exchange of information.

Requirements Management and Compliance Traceability

A fundamental requirement under the MDR is the ability to track and demonstrate how a device meets regulatory and safety standards throughout its lifecycle. This entails ensuring that:

• Each design element links to specific regulatory requirements.
• Changes in requirements are reflected in design updates.
• Traceability extends to post-market modifications.

Weak traceability mechanisms can lead to delayed approvals, additional testing, or non-compliance penalties. Violating the EU Medical Device Regulation (MDR) can have serious consequences, including fines, market access loss, product recalls, and potential lawsuits, depending on the severity of the infraction. For example, in Italy, manufacturers without a compliant quality management system may face fines ranging from €24,200 to €145,000, while importers failing to retain the Declaration of Conformity can be fined between €20,000 and €120,000.

Altium 365 Requirements & Systems Portal enables engineers to connect design data directly to compliance-related standards, such as:

• RoHS (Restriction of Hazardous Substances)
• REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals)
• FDA 21 CFR Part 820 (Quality System Regulation for medical devices)
• IEC 60601-1 (Medical electrical equipment safety standard)
• ISO 13485 (Quality management systems for medical devices)

By linking design data with compliance requirements, teams can facilitate smoother audits and reduce the many risks associated with non-compliance.

Impact on Design Processes: Adapting to MDR Compliance

The MDR’s stringent requirements necessitate a shift in how design teams operate. Key adaptations include:

1. Increased Cross-Functional Collaboration

Under MDR, compliance is not solely the responsibility of regulatory teams. Engineers, designers, and quality specialists must work closely together to ensure that all regulatory requirements are met at every stage of development. A collaborative platform like Altium 365 makes sharing insights, documenting decisions, and ensuring alignment between technical and regulatory teams easier.

2. Proactive Risk Management

MDR mandates that manufacturers implement a risk management plan that spans the entire lifecycle of a medical device. This includes:

• Identifying and assessing risks during the design phase
• Documenting mitigation strategies
• Monitoring post-market performance and making necessary updates

Having an integrated system for managing design data ensures that risk management considerations are factored into every stage of development.

3. Continuous Education and Process Improvement

Regulatory landscapes evolve, and staying compliant requires ongoing education. Design teams must:

• Stay updated on MDR amendments and industry best practices
• Invest in training to ensure that compliance processes are fully understood
• Utilize digital tools that simplify regulatory tracking and updates
