Medical devices utilizing animal tissues and their derivatives - Part 1: Application of risk management (ISO 22442-1:2020)

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.

Tierische Gewebe und deren Derivate, die zur Herstellung von Medizinprodukten eingesetzt werden - Teil 1: Anwendung des Risikomanagements (ISO 22442-1:2020)

Dieses Dokument bezieht sich auf Medizinprodukte, mit Ausnahme von in vitro Diagnostika, hergestellt unter Verwendung von Materialien tierischen Ursprungs, die nicht lebensfähig sind oder abgetötet wurden. Es legt in Verbindung mit ISO 14971 ein Verfahren zur Identifizierung der Gefahren und gefährlichen Situationen im Zusammenhang mit diesen Produkten, zur Abschätzung und Beurteilung der sich ergebenden Risiken, zur Kontrolle dieser Risiken und zur Überwachung der Wirksamkeit dieser Kontrolle fest. Zusätzlich umschreibt es den Entscheidungsprozess für die Annehmbarkeit des Restrisikos, indem das Restrisiko, wie in ISO 14971 definiert, abgewägt und der erwartete medizinische Nutzen, verglichen mit verfügbaren Alternativen, einander gegenübergestellt wird. Dieses Dokument soll Anforderungen und Anleitungen für das Risikomanagement in Bezug auf typische Gefährdungen durch Medizinprodukte bereitstellen, die unter Verwendung tierischer Gewebe und deren Derivate hergestellt wurden, z. B.
a) Verunreinigungen durch Bakterien, Schimmelpilze oder Hefepilze;
b) Verunreinigungen durch Viren;
c) Verunreinigungen durch Erreger, die übertragbare spongiforme Enzephalopathien (en: transmissible spongiform encephalopathies, TSE) hervorrufen;
d) für ungewünschte pyrogene, immunologische oder toxikologische Reaktionen verantwortliches Material.
Bei Parasiten und anderen nicht klassifizierten pathogenen Einheiten können ähnliche Prinzipien gelten.
Dieses Dokument legt keine Anforderungen für die Akzeptanz fest, weil diese von einer Vielzahl von Faktoren bestimmt und in einer solchen Internationalen Norm nicht festgelegt werden können. Ausgenommen sind bestimmte Derivate, die in Anhang C erwähnt werden. Anhang C legt Grade für die Annehmbarkeit von TSE Risiken bei Talg Derivaten, Kohle aus tierischem Ausgangsmaterial, Milch und Milch Derivaten, Derivaten von Wolle und Aminosäuren fest.
Dieses Dokument legt kein Qualitätsmanagementsystem zur Kontrolle aller Produktionsschritte eines Medizinproduktes fest.
Dieses Dokument behandelt nicht die Verwendung von menschlichen Geweben in Medizinprodukten.
ANMERKUNG 1 Es ist keine Anforderung von diesem Dokument, ein vollständiges Qualitätsmanagementsystem für die Herstellung zu nutzen. Es wird jedoch auf Internationale Normen für Qualitätsmanagementsysteme (siehe ISO 13485) zur Kontrolle aller Schritte der Produktion und Wiederaufarbeitung von Medizinprodukten hingewiesen.
ANMERKUNG 2 Eine Anleitung zur Anwendung dieses Dokuments ist in Anhang A gegeben.

Le présent document s'applique aux dispositifs médicaux autres que les dispositifs médicaux de diagnostic in vitro, dans la fabrication desquels entrent des matériaux d'origine animale non viables ou rendus non viables. Associé à l'ISO 14971, il spécifie un mode opératoire permettant d'identifier les dangers et les situations dangereuses associés à de tels dispositifs, d'estimer et d'évaluer les risques qui en découlent, de maîtriser ces risques et de surveiller l'efficacité de cette maîtrise. En outre, il décrit le processus décisionnel relatif à l'acceptabilité du risque résiduel, en tenant compte du rapport entre le risque résiduel, tel que défini dans l'ISO 14971, et le bénéfice médical escompté par rapport aux solutions de remplacement disponibles. Le présent document est destiné à fournir des exigences et des préconisations pour la gestion des risques associée aux dangers typiques des dispositifs médicaux dans la fabrication desquels entrent des tissus ou des dérivés d'origine animale, notamment:
a)    la contamination par des bactéries, des moisissures ou des levures;
b)    la contamination par des virus;
c)    la contamination par des agents responsables d'encéphalopathies spongiformes transmissibles (EST);
d)    un matériau provoquant des réactions pyrogènes, immunologiques ou toxicologiques indésirables.
Des principes similaires peuvent s'appliquer aux parasites et autres entités pathogènes non classées.
Le présent document ne stipule pas de niveaux d'acceptabilité qui, du fait qu'ils sont déterminés par de multiples facteurs, ne peuvent s'inscrire dans une telle Norme internationale, excepté pour certains dérivés particuliers mentionnés à l'Annexe C. L'Annexe C stipule des niveaux d'acceptabilité du risque d'EST pour les dérivés du suif, le noir animal, le lait et les dérivés du lait, les dérivés de la laine et les acides aminés.
Le présent document ne spécifie pas un système de management de la qualité permettant le contrôle de toutes les étapes de fabrication de dispositifs médicaux.
Le présent document ne couvre pas l'utilisation de tissus humains dans les dispositifs médicaux.
NOTE 1    Le présent document n'exige pas un système de management de la qualité complet lors de la fabrication. Toutefois, il est préférable de se référer aux Normes internationales relatives aux systèmes de management de la qualité (voir l'ISO 13485) qui contrôlent toutes les étapes de fabrication ou de retraitement des dispositifs médicaux.

the scope of this standard, a presumption of conformity with the corresponding essential requirements

of that Directive and associated EFTA regulations.

NOTE 1 Where a reference from a clause of this standard to the risk management process is made, the risk

management process needs to be in compliance with Directive 93/42/EEC as amended by 2007/47/EC. This

means that risks have to be reduced ‘as far as possible’, ‘to a minimum’, ‘to the lowest possible level’, ‘minimized’

or ‘removed’, according to the wording of the corresponding essential requirement.

NOTE 2 The manufacturer’s policy for determining acceptable risk must be in compliance with Essential

Requirements 1, 2, 5, 6, 7, 8, 9, 11 and 12 of the Directive.

NOTE 3 This Annex ZA is based on normative references according to the table of references in the European

foreword, replacing the references in the core text.

Introduction
Certain medical devices utilize materials of animal origin.

Animal tissues and their derivatives are used in the design and manufacture of medical devices to

provide performance characteristics that have been chosen for advantages over non-animal based

materials. The range and quantities of materials of animal origin in medical devices vary. These

materials can comprise a major part of the device (e.g. bovine/porcine heart valves, bone substitutes

for use in dental or orthopaedic applications, haemostatic devices), can be a product coating or

impregnation (e.g. collagen, gelatine, heparin), or can be used in the device manufacturing process (e.g.

tallow derivatives such as oleates and stearates, foetal calf serum, enzymes, culture media).

ISO 14971 is a general standard which specifies a process for a manufacturer by identifying hazards

and hazardous situations associated with medical devices, including in vitro medical devices, to

estimate and evaluate the risks associated with those hazards, to control these risks and to monitor the

effectiveness of the control throughout the life cycle. This document provides additional requirements

and guidance for the evaluation of medical devices manufactured utilizing animal tissues or derivatives

which are non-viable or rendered non-viable.

This document is intended to cover medical devices including active implantable medical devices such

as implantable infusion pumps.
This document does not apply to in vitro diagnostic devices.

This document can only be used in combination with ISO 14971 and is not a “stand-alone” standard.

NOTE Compliance to this document is shown by fulfilling its specified requirements. The guidance given in

the notes and the informative annexes is not normative and is not provided as a checklist for auditors.

Part 1:
Application of risk management
1 Scope

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.

3.1
animal

vertebrate or invertebrate [including amphibian, arthropod (e.g. crustacean), bird, coral, fish, reptile,

mollusc and mammal] excluding humans (Homo sapiens)
3.2
cell

smallest organized unit of any living form which is capable of independent existence and of replacement

of its own substance in a suitable environment
3.3
derivative

substance obtained from an animal (3.1) material which is involved directly in the manufacturing

process of the medical device or is part of the final medical device

EXAMPLE Hyaluronic acid, collagen, gelatine, monoclonal antibodies, chitosan and albumin.

3.4
elimination
removal
process by which the number of transmissible agents is reduced

Note 1 to entry: The effectiveness of the process for the elimination of viruses and TSE agents should be expressed

mathematically in terms of a reduction factor (see C.2 and ISO 22442-3:2007, Annex F).

Note 2 to entry: Elimination aims to prevent infection or pathogenic reaction caused by transmissible agents.

3.5
inactivation

process by which the ability to cause infection or pathogenic reaction by a transmissible agent is reduced

Note 1 to entry: The effectiveness of the process for inactivation of viruses and TSE agents should be expressed

mathematically in terms of a reduction factor (see ISO 22442-3:2007, Annex F).

Note 2 to entry: Inactivation aims to prevent infection by, and replication of, transmissible agents.

3.6
medical device

instrument, apparatus, implement, machine, appliance, implant, reagent for in vitro use, software,

material or other similar or related article, intended by the manufacturer to be used, alone or in

combination, for human beings, for one or more of the specific medical purpose(s) of

— diagnosis, prevention, monitoring, treatment or alleviation of disease,

— diagnosis, monitoring, treatment, alleviation of or compensation for an injury,
