  • General Purpose: The Regulation aims to establish a robust, transparent, and sustainable regulatory framework for medical devices to ensure a high level of safety and health whilst supporting innovation. It replaces Council Directives 90/385/EEC (Active Implantable Medical Devices) and 93/42/EEC (Medical Devices).

  • Dual Objectives:

    • Smooth functioning of the internal market regarding medical devices.

    • High level of protection of health for patients and users, including high standards of quality and safety.

  • Key Amendments: It amends Directive 2001/83/EC, Regulation (EC) No 178/2002, and Regulation (EC) No 1223/2009. It clarifies that medical devices are excluded from the scope of food law (Regulation (EC) No 178/2002).

Scope and Key Definitions (Article 1 & 2)

  • Medical Device Definition: Any instrument, apparatus, appliance, software, implant, reagent, material, or other article intended for human use (diagnosis, prevention, monitoring, treatment, alleviation of disease/injury/disability, or investigation of anatomy/physiology) that does not achieve its principal action by pharmacological, immunological, or metabolic means.

  • Included Products:

    • Devices for control or support of conception.

    • Products for cleaning, disinfection, or sterilization of medical devices.

    • Products without an intended medical purpose as listed in Annex XVI (e.g., contact lenses, dermal fillers, liposuction equipment).

  • Exclusions:

    • In vitro diagnostic devices (regulated by Regulation (EU) 2017/746).

    • Medicinal products (Directive 2001/83/EC).

    • Cosmetic products (Regulation (EC) No 1223/2009).

    • Viable biological materials or organisms.

  • Active Device: Operation depends on an energy source other than the human body or gravity. Software is also deemed an active device.

  • Implantable Device: Intended to be totally introduced or to replace an epithelial surface/surface of the eye by clinical intervention, remaining for at least 3030 days.

  • Nanomaterial: Material containing particles where 50%50 \% or more have one or more external dimensions in the range 11 to 100100 nm.

Obligations of Economic Operators (Chapter II)

  • Manufacturers (Article 10):

    • Must ensure devices are designed and manufactured per Regulation requirements.

    • Establish and maintain a Quality Management System (QMS) and a Risk Management System.

    • Conduct clinical evaluation and maintain technical documentation.

    • Draw up an EU Declaration of Conformity and affix the CE marking.

    • Responsible for the Unique Device Identification (UDI) system assignment.

    • Financial Coverage: Must have measures (proportional to risk class) to provide sufficient financial coverage for potential liability.

  • Authorised Representatives (Article 11): Mandatory for manufacturers located outside the EU. They are legally liable for defective devices on the same basis as the manufacturer if the manufacturer fails to comply with obligations.

  • Importers (Article 13): Must verify CE marking, identification of manufacturer/representative, and UDI assignment. They must ensure storage and transport conditions do not jeopardize compliance.

  • Distributors (Article 14): Must act with due care and verify compliance (CE mark, instructions, labels) before making devices available.

  • Person Responsible for Regulatory Compliance (Article 15): Manufacturers and Authorised Representatives must have at least one person with requisite expertise (e.g., degree + 11 year experience or 44 years' experience) available at all times.

Classification and Conformity Assessment (Chapter V)

  • Classification (Article 51): Devices are divided into Classes I, IIa, IIb, and III based on intended purpose and inherent risks. Class III represents the highest risk.

  • Conformity Procedures (Article 52):

    • Class III: Requires assessment per Annex IX (QMS and Technical Documentation) or Annex X (Type-examination) + Annex XI (Product verification).

    • Class IIb: Assessment of QMS and technical documentation for at least one representative device per generic group.

    • Class IIa: Assessment of QMS and technical documentation for at least one representative device per category.

    • Class I: Manufacturer's responsibility to declare conformity, except for sterile, measuring, or reusable surgical instruments (where a Notified Body is involved).

  • Clinical Evaluation Consultation (Article 54): Certain Class III and IIb devices require a consultation with expert panels on the clinical evaluation report.

Identification, Traceability, and Eudamed (Chapter III)

  • UDI System (Article 27): Consists of a UDI-DI (device identifier) and UDI-PI (production identifier). It must be placed on labels and all higher levels of packaging.

  • Eudamed (Article 33): The European database on medical devices integrates systems for registration, UDI, certificates, clinical investigations, vigilance, and market surveillance. It aims to increase transparency and facilitate info flow.

  • Summary of Safety and Clinical Performance (SSCP): Required for Class III and implantable devices. It must be clear to intended users/patients and accessible via Eudamed.

Clinical Evaluation and Investigations (Chapter VI)

  • Clinical Evaluation (Article 61): Confirmation of conformity must be based on clinical data providing sufficient clinical evidence. Evaluation must be updated throughout the lifecycle with post-market clinical follow-up (PMCF) data.

  • Clinical Investigations (Article 62): Must protect the rights, safety, and well-being of subjects. Requires authorization by Member States and a positive opinion from an ethics committee. Informed consent is mandatory.

  • Vulnerable Populations: Specific protection measures are required for incapacitated subjects, minors, and pregnant/breastfeeding women.

Vigilance and Market Surveillance (Chapter VII)

  • Post-Market Surveillance (PMS): Manufacturers must proactively collect and review experience from devices to identify corrective/preventive actions.

  • Periodic Safety Update Report (PSUR): Required for Class IIa, IIb, and III devices. Class IIb and III must update at least annually.

  • Reporting Serious Incidents (Article 87):

    • Immediate reporting of serious public health threats within 22 days.

    • Reporting of death or unanticipated deterioration within 1010 days.

    • General serious incidents must be reported within 1515 days.

  • Field Safety Corrective Action (FSCA): Manufacturer must bring actions to the attention of users via a Field Safety Notice.

Notified Bodies (Chapter IV)

  • Criteria: Must be independent, impartial third-party bodies with competent personnel and a quality management system. Requirements are detailed in Annex VII.

  • Oversight: Member States appoint an authority responsible for assessing, designating, and monitoring notified bodies.

  • Joint Assessment Team: Includes representatives from the Commission and other Member States to review applications for notification.

Annex I: General Safety and Performance Requirements

  • Design for Safety: Manufacturers must eliminate/reduce risks through safe design, then protection measures (alarms), then info for safety (warnings).

  • Chemical/Biological Properties: Special attention to toxicity, flammability, and CMR (Carcinogenic, Mutagenic, or toxic to Reproduction) substances. Concentration of CMR/Endocrine-disruptors above 0.1%0.1 \% weight by weight (w/ww/w) must be justified.

  • Labeling and IFU: Requirements for indelible labels and instructions for use (IFU) in official Union languages. IFUs are generally required except for Class I and IIa where safe use is possible without them.

Similarities in the development of medical devices and drugs include:

  • Both require extensive research and development to ensure safety and efficacy.

  • Each undergoes regulatory scrutiny and must comply with health and safety standards before market entry.

  • Both typically involve preclinical studies followed by clinical trials to assess their effects on human subjects.

  • They require extensive documentation and reporting to regulatory bodies to demonstrate compliance and gain approval.

Differences include:

  • Regulatory Pathways: Medical devices are often regulated under different frameworks (e.g., Regulation (EU) 2017/745) than drugs (Directive 2001/83/EC).

  • Approval Process: The approval process for drugs tends to be more rigorous and time-consuming, focusing heavily on clinical trial data, while some lower-risk medical devices may follow a more streamlined process (like the CE marking for Class I devices).

  • Variability in Testing: The testing protocols differ; drugs are tested for pharmacological effects, while devices are evaluated for safety, performance, and adherence to regulatory specifications.

  • Market Surveillance: Post-market surveillance and monitoring might differ, with distinct requirements for clinical evaluations and post-market clinical follow-ups for medical devices compared to drugs.
