European Medical Device Regulation (MDR) replaced previous directives in 2017
Aims to enhance patient safety and modernize public health
Introduces more stringent requirements for clinical evaluation and post-market surveillance
Expands the definition of medical devices to include software and certain cosmetic products
CE Marking signifies compliance with European health, safety, and environmental standards
Mandatory for medical devices sold in the European Economic Area
Involves a conformity assessment process
Allows free movement of products within the EU market
Manufacturers must follow specific steps to obtain CE marking
Identify applicable directives and harmonized standards
Verify product-specific requirements
Determine need for independent conformity assessment
Test product and check conformity
Compile technical documentation
Affix CE marking and draft EU Declaration of Conformity
Role of Notified Bodies
Notified Bodies play a crucial role in the conformity assessment process
Independent organizations designated by EU member states
Assess whether products meet the necessary requirements for CE marking
Responsibilities of Notified Bodies include
Reviewing technical documentation
Conducting quality management system audits
Issuing certificates of conformity
Notified Bodies must maintain impartiality and confidentiality
Subject to regular audits by national authorities
Can have their designation revoked if found non-compliant
International Harmonization Efforts
Global Regulatory Collaboration
International Medical Device Regulators Forum (IMDRF) advances global harmonization
Voluntary group of medical device regulators from various countries
Develops internationally agreed-upon documents for medical devices
Aims to accelerate international regulatory convergence
Global Harmonization Task Force (GHTF) preceded IMDRF
Established in 1992 to achieve greater uniformity between national medical device regulatory systems
Developed guidance documents on various aspects of medical device regulation
Transitioned into IMDRF in 2011 to better address global challenges
Regulatory Cooperation and Standardization
Mutual Recognition Agreements (MRA) facilitate trade between countries
Bilateral agreements recognizing each other's conformity assessment procedures
Reduce duplication of testing and certification for manufacturers
Examples include agreements between EU-US and EU-Canada
International Conference on Harmonisation (ICH) focuses on pharmaceutical regulations
Brings together regulatory authorities and pharmaceutical industry
Develops guidelines to ensure safety, efficacy, and quality of medicines
Harmonizes interpretation and application of technical guidelines and requirements
International Standards
ISO Standards in Medical Device Industry
International Organization for Standardization (ISO ) develops global standards
ISO 13485 specifies requirements for quality management systems in medical devices
Ensures consistent design, development, production, and distribution
Facilitates regulatory compliance across different markets
ISO 14971 provides a framework for risk management in medical devices
Helps manufacturers identify hazards and estimate associated risks
Guides implementation of risk control measures
Benefits of adhering to ISO standards include
Improved product quality and safety
Enhanced market access and competitiveness
Streamlined regulatory approval processes
ISO standards are regularly reviewed and updated
Reflect technological advancements and changing regulatory landscapes
Involve input from industry experts, regulators, and other stakeholders
