Overview
ISO/TR 8417:2024 - Risk management of particulate contamination for devices with intravascular access - is a Technical Report from ISO that guides manufacturers, regulators and healthcare stakeholders on identifying, assessing and controlling particulate contamination in devices used to provide intravenous access. The document emphasizes applying ISO 14971 risk-management methodology rather than relying solely on fixed particle-count limits, and explains approaches for determining particulate loads and for comprehensive risk analysis across design, manufacturing and clinical use.
Key topics and requirements
- Risk-based approach: Apply ISO 14971 principles to identify particulate hazards, assess severity and probability, and implement risk controls specific to intravascular devices.
- Determination of particulate loads: Use quantitative and qualitative testing to assess initial particle loads and to verify effectiveness of control measures. ISO/TR 8417 references applicable methods such as ISO 8536-4:2019 (A.2), European Pharmacopoeia (2.9.19, 2.9.20), USP chapters (787, 788, 790, 1790), Japanese Pharmacopoeia (6.07, 6.06) and ISO/TR 19727.
- Comprehensive source analysis: Identify particle sources across the product lifecycle - design (moulding, extrusion), suppliers, packaging, assembly, sterilization, storage, transport and clinical application. Annex A provides examples of hazards and risk-control options.
- Holistic exposure perspective: Recognizes that patients’ total particulate exposure is cumulative (containers, infusion sets, catheters, parallel or sequential infusions) and that fixed “tolerable” counts may be insufficient as sole assurance of safety.
- Documentation expectations: Manufacturers are expected to create or update risk management files to include particulate-related hazards and feasible control measures.
Practical applications
- Device design teams: integrate particulate-reduction features (material selection, geometry, barrier design) and design-for-cleanliness.
- Manufacturing and quality assurance: adopt cleanroom controls, supplier qualification, incoming inspection, validated moulding/extrusion and particulate testing to monitor loads.
- Regulatory and compliance: use the TR to inform risk analyses, technical files and post-market surveillance arguments about particulate risk control.
- Clinical risk managers and procurement: assess device combinations and instructions for use (filters, contraindications) to reduce patient exposure.
Who will use this standard
- Medical device manufacturers (infusion sets, IV catheters, administration sets)
- Regulatory authorities, notified bodies and standards committees
- Quality, RA and R&D teams developing intravascular-access devices
- Hospital procurement, clinical engineers and patient safety officers
