Résumé

This document applies to medical devices other than in vitro diagnostic medical devices manufactured utilizing materials of human origin. The materials are non-viable or have been rendered non-viable. The document specifies, in junction with ISO 14971, a procedure to identify the hazards and hazardous situations associated with such devices, to estimate and evaluate the resulting risks, to control these risks and to monitor the effectiveness of that control. Furthermore, it outlines the decision process for the residual risk acceptability, taking into account the balance of residual risk, as defined in ISO 14971, and expected medical benefit as compared to available alternatives. This document is intended to provide requirements and guidance on risk management related to the hazards typical of medical devices manufactured utilizing human tissues or derivatives such as: a) contamination by bacteria, moulds or yeasts; b) contamination by viruses; c) contamination by agents causing Transmissible Spongiform Encephalopathies (TSE); d) material responsible for undesired pyrogenic, immunological or toxicological reactions. For parasites and other unclassified pathogenic entities, similar principles can apply. This document does not stipulate levels of acceptability, because they are determined by a multiplicity of factors. This document does not specify a quality management system for the control of all stages of production of medical devices.
