Overview
ISO/TR 18965:2025 - Medical devices - Examples of the application of the risk management process to cardiac valve replacement and repair systems is an informative ISO Technical Report providing practical guidance on implementing risk management for cardiac valve replacement and repair systems throughout the total product life cycle. This document supports manufacturers by illustrating how risk management concepts and requirements can be integrated into the development, production, and post-production phases of cardiac valve systems, including new or modified devices. The examples included are not exhaustive but serve as practical references for applying risk management to these critical, high-risk medical devices.
Key Topics
- Risk Management Process: Step-by-step examples demonstrate risk management as described in ISO 14971, focusing on the identification, analysis, evaluation, and control of risks associated with cardiac valve replacement and repair devices.
- Intended Use and Foreseeable Misuse: The standard emphasizes defining device intended use, identifying user populations, use environments, and foreseeable misuse to ensure effective risk identification.
- Hazard and Harm Identification: Practical examples are provided for detecting hazards, hazardous situations, and possible patient harms specific to cardiac and valve interventions, such as blood loss, device migration, or annular rupture.
- Risk Estimation: The document illustrates risk estimation practices, including probability of occurrence and severity classification, leveraging data from bench testing, historical clinical data, and expert judgment.
- Risk Control Measures: Guidance is given on developing, implementing, and monitoring risk control actions-such as design modifications, user training, and updated labelling-to reduce and manage device-associated hazards.
- Residual Risk and Benefit-Risk Analysis: Examples help manufacturers evaluate residual risks after controls have been applied, and conduct benefit-risk analyses, particularly when risks cannot be further reduced.
- Life Cycle Integration: Emphasis on risk management as a continuous, life-cycle spanning process, including production and post-production activities, ongoing clinical feedback, and regulatory compliance.
Applications
ISO/TR 18965:2025 is highly relevant for:
- Medical Device Manufacturers: Provides concrete guidance and templates to support compliance with international risk management requirements for cardiac valve devices.
- Design and Development Teams: Assists design engineers and project managers in integrating risk management activities into product development, verification, and validation of cardiac valve replacements and repairs.
- Quality and Regulatory Affairs Professionals: Supports conformity with ISO 13485 and ISO 14971, and preparation for regulatory submissions by providing real-world, device-specific examples of risk analysis and benefit-risk assessments.
- Clinical and Post-Market Teams: Encourages the continued assessment of clinical data and user feedback to ensure the ongoing safety and effectiveness of cardiac valve products.
- Training and Documentation: Can be used to develop staff training materials, SOPs, and risk management files tailored for cardiovascular implant manufacturers.
