The European Union’s Artificial Intelligence Act (AI Act), which entered into force on August 1, 2024, represents a pioneering effort to regulate AI technologies across various sectors, including healthcare. This legislation introduces a comprehensive framework aimed at ensuring the safe and ethical deployment of AI systems, significantly impacting the development and use of AI-enabled medical devices.
The EU AI Act was created in response to growing concerns over the ethical and safety implications of artificial intelligence. Several high-profile cases of AI bias and failure—including misdiagnoses in AI-assisted healthcare tools—highlighted the need for robust oversight. By setting clear guidelines for development, testing, and deployment, the AI Act aims to foster innovation while protecting patient safety and fundamental rights.
Classification of AI-Enabled Medical Devices
Under the AI Act, AI systems are categorized based on their risk levels:
- Unacceptable Risk: AI applications that pose a clear threat to safety or fundamental rights are prohibited.
- High Risk: AI systems that could significantly affect health, safety, or fundamental rights, such as those used in medical devices, are subject to stringent regulations.
- Limited and Minimal Risk: These categories involve fewer obligations, focusing primarily on transparency and oversight.
AI-enabled medical devices are classified as high-risk due to their direct impact on patient health and safety. Consequently, they must comply with rigorous requirements to ensure their reliability and ethical use.
Key Obligations for High-Risk AI Systems
Manufacturers of AI-enabled medical devices must adhere to several critical obligations:
- Quality Management System (QMS): Implement a QMS that ensures compliance with the AI Act’s standards, encompassing processes for design, development, testing, and post-market surveillance.
- Technical Documentation: Maintain comprehensive documentation detailing the AI system’s design, intended purpose, performance metrics, and risk assessments.
- Data Governance: Ensure that training, validation, and testing datasets are relevant, representative, and free from errors to prevent biases and inaccuracies.
- Transparency and Information Provision: Provide clear instructions for use, including the AI system’s capabilities, limitations, and any associated risks, enabling users to operate the device safely and effectively.
- Human Oversight: Design AI systems to allow human intervention, ensuring that operators can oversee and, if necessary, override AI decisions to maintain patient safety.
- Accuracy and Cybersecurity: Ensure the AI system’s accuracy, robustness, and resilience against cybersecurity threats, protecting patient data and device functionality.

Integration with Existing Medical Device Regulations
The AI Act is designed to complement existing EU regulations, such as the Medical Device Regulation (MDR) and the In Vitro Diagnostic Medical Device Regulation (IVDR). This integrated approach aims to streamline compliance processes for manufacturers. For instance, the AI Act allows for a single conformity assessment that addresses both AI-specific requirements and those under the MDR or IVDR. However, this necessitates that notified bodies possess expertise in both regulatory domains, which could present practical challenges.
Support for Small and Medium-Sized Enterprises (SMEs)
Recognizing the potential burden on SMEs, the AI Act includes provisions to assist these entities in achieving compliance:
- Regulatory Sandboxes: Establishment of controlled environments where companies can develop and test AI systems under regulatory supervision, facilitating innovation while ensuring adherence to standards.
- Educational Support: Member states are encouraged to provide SMEs with education and information to navigate compliance requirements effectively.
- Fee Adjustments: Notified bodies are urged to consider fee reductions for conformity assessments and translation services for smaller entities, alleviating financial pressures.
Challenges and Considerations
Despite efforts to harmonize regulations, manufacturers may face challenges, including:
- Resource Constraints: Notified bodies may require additional expertise to assess AI systems adequately, potentially leading to delays and increased costs.
- Regulatory Overlaps: Navigating overlapping requirements between the AI Act and existing medical device regulations could create complexities, particularly concerning definitions and compliance procedures.
- Data Privacy Concerns: Aligning the AI Act’s data governance requirements with the General Data Protection Regulation (GDPR) is crucial to ensure patient data privacy and security.
The EU AI Act establishes a robust framework for the development and deployment of AI-enabled medical devices, emphasizing safety, transparency, and ethical considerations. While it presents opportunities for innovation, manufacturers must diligently navigate the regulatory landscape to ensure compliance and maintain patient trust. Ongoing dialogue between regulators, industry stakeholders, and healthcare professionals will be essential to address challenges and optimize the integration of AI in medical devices.
