Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizati

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the

20、 ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of t

27、ing. ISO 10993-3:2003(E) vi ISO 2003 All rights reservedIntroduction The basis for biological evaluation of medical devices is often empirical and driven by the relevant concerns for human safety. The risk of serious and irreversible effects, such as cancer or second-generation abnormalities, is of

28、particular public concern. It is inherent in the provision of safe medical devices that such risks be minimized to the greatest extent feasible. The assessment of mutagenic, carcinogenic and reproductive hazards is an essential component of the control of these risks. Not all test methods for the as

29、sessment of genotoxicity, carcinogenicity or reproductive toxicity are equally well developed, nor is their validity well established for the testing of medical devices. Significant issues in test sample size and preparation, scientific understanding of disease processes and test validation can be c

30、ited as limitations of available methods. For example, the biological significance of solid state carcinogenesis is poorly understood. It is expected that ongoing scientific and medical advances will alter our understanding of and approaches to these important toxicity test methods. At the time this

31、 part of ISO 10993 was prepared, the test methods proposed were those most acceptable. Scientifically sound alternatives to the proposed testing may be acceptable insofar as they address relevant matters of safety assessment. In the selection of tests needed to evaluate a particular medical device,

32、there is no substitute for a careful assessment of expected human uses and potential interactions of the medical device with various biological systems. These considerations will be particularly important in such areas as reproductive and developmental toxicology. This part of ISO 10993 presents tes

33、t methods for the detection of specific biological hazards, and strategies for the selection of tests, where appropriate, that will assist in hazard identification. Testing is not always necessary or helpful in hazard identification but, where it is appropriate, it is important that maximum test sen

34、sitivity be achieved. Most tests included in this part of ISO 10993 refer to Guidelines for Testing of Chemicals, prepared by the Organization for Economic Cooperation and Development (OECD). The interpretation of findings and their implications for human health effects are beyond the scope of this

35、part of ISO 10993. Because of the multitude of possible outcomes and the importance of factors such as extent of exposure, species differences and mechanical or physical considerations, risk assessment has to be performed on a case-by-case basis.

43、test test to determine the tumorigenic potential of medical devices, materials and/or extracts using either single or multiple exposures over a major portion of the life span of the test animal NOTE These tests may be designed to examine both chronic toxicity and tumorigenicity in a single experimen

44、tal study. When chronic toxicity and carcinogenicity are evaluated within a single study, care in study design with emphasis on dose selection should be exercised. This will help to ensure that premature mortality from chronic/cumulative toxicity does not compromise the statistical evaluation of ani

45、mals that survive until scheduled study termination (i.e. normal life-span). 3.2 energy-depositing medical device device intended to exert its therapeutic or diagnostic effect by the delivery of electromagnetic radiation, ionizing radiation or ultrasound NOTE This does not include medical devices th

46、at deliver simple electrical current, such as electrocautery medical devices, pacemakers or functional electrical stimulators. 3.3 genotoxicity test test using mammalian or non-mammalian cells, bacteria, yeasts or fungi to determine whether gene mutations, changes in chromosome structure, or other D

47、NA or gene changes are caused by the test samples NOTE These tests can include whole animals. 3.4 maximum tolerated dose MTD maximum dose that a test animal can tolerate without any adverse physical effects 3.5 reproductive and developmental toxicity test test to evaluate the potential effects of te

49、ization of materials (ISO 10993-18) shall be taken into account. The rationale for a test programme, taking into consideration all relevant factors, shall be documented. ISO 10993-1 indicates circumstances where the potential for genotoxicity is a relevant hazard for consideration in an overall biological safety evaluation (see ISO 10993-1:1997, Table 1). Testing for genotoxicity, however, is not necessary for medical devices, and components thereof, made only from materials known to
