CEN/TC 316 - Medical devices utilizing tissues

This document 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. It specifies, in conjunction 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 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 can apply.
This document does not stipulate levels of acceptability which, because they are determined by a multiplicity of factors, cannot be set down in such an international standard except for some particular derivatives mentioned in Annex C. Annex C stipulates levels of TSE risk acceptability for tallow derivatives, animal charcoal, milk and milk derivatives, wool derivatives and amino acids.
This document does not specify a quality management system for the control of all stages of production of medical devices.
This document does not cover the utilization of human tissues in medical devices.
NOTE 1  It is not a requirement of this document to have a full quality management system during manufacture. However, attention is drawn to international standards for quality management systems (see ISO 13485) that control all stages of production or reprocessing of medical devices.
NOTE 2  For guidance on the application of this document, see Annex A.

This document specifies requirements for controls on the sourcing, collection, and handling (which includes storage and transport) of animals and tissues for the manufacture of medical devices utilizing materials of animal origin other than in vitro diagnostic medical devices. It applies where required by the risk management process as described in ISO 22442‑1.
NOTE       Selective sourcing is especially important for transmissible spongiform encephalopathy (TSE) risk management, i.e. when utilising animal tissue and/or their derivative originating from bovine, ovine and caprine species, deer, elk, mink or cats.
This document does not cover the utilization of human tissues in medical devices.
This document does not specify a quality management system for the control of all stages of production of medical devices.

ISO 22442-2:2015 specifies requirements for controls on the sourcing, collection, and handling (which includes storage and transport) of animals and tissues for the manufacture of medical devices utilizing materials of animal origin other than in vitro diagnostic medical devices. It applies where required by the risk management process as described in ISO 22442‑1.
NOTE 1 Selective sourcing is considered to be especially important for transmissible spongiform encephalopathy (TSE) risk management.
The manufacturers should refer to ISO 22442‑3 for information on the validation of the elimination and/or inactivation of viruses and TSE agents.
ISO 22442-2:2015 does not cover the utilization of human tissues in medical devices.
ISO 22442-2:2015 does not specify a quality management system for the control of all stages of production of medical devices.
It is not a requirement of this part of ISO 22442 to have a full quality management system during manufacture, but it does specify requirements for some of the elements of a quality management system. Attention is drawn to the standards for quality management systems (see ISO 13485) that control all stages of production or reprocessing of medical devices. The quality management system elements that are required by this part of ISO 22442 can form a part of a quality management system conforming to ISO 13485.
NOTE 2 A general principle for the application of this International Standard is that it is advisable to give due consideration to the requirements and recommendations contained in all three parts of the standard.
