Medical devices utilizing animal tissues and their derivatives - Part 1: Application of risk management
1 Scope
This part of YY/T 0771 specifies, in conjunction with YY/T 0316-2016, a procedure to identify the hazards and hazardous situations associated with medical devices manufactured utilizing materials of animal origin (which are non-viable or have been rendered non-viable), to estimate and evaluate the resulting risks, to control these risks, and to monitor the effectiveness of that control.
This part applies to medical devices other than in vitro diagnostic medical devices manufactured utilizing materials of animal origin, which are non-viable or have been rendered non-viable.
This part does not apply to medical devices utilizing human tissues.
This part does not specify a quality management system for the control of all stages of production of medical devices.
Furthermore, it outlines the decision process for the residual risk acceptability, taking into account the balance of residual risk, as defined in YY/T 0316-2016, and expected medical benefit as compared to available alternatives. This part is intended to provide requirements and guidance on risk management related to the hazards typical of medical devices manufactured utilizing animal 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 may apply.
Note 1: It is not a requirement of this part to have a full quality management system during manufacture. However, attention is drawn to YY/T 0287 for quality management systems that control all stages of production or reprocessing of medical devices.
Note 2: For guidance on the application of this part, see Annex A.
