Tests for Neurotoxicity5.1 Testing should be performed on the final sterilizeddevice, representative samples from the final sterilized device,or materials processed in the same manner as

16、 the final sterilizeddevice. Testing of individual materials may be useful forresearch and development, but the definitive neurotoxicityevaluation should include all materials in the final version ofthe device. The test article should be exposed to all phases ofmanufacturing including processing, cl

17、eaning, sterilization,and packaging.5.1.1 A complete description of all device materials andreagents used during manufacturing and processing should beprovided with information on the source, purity, and toxicityprofile. Chemical characterization studies can provide addi-tional information on the de

18、vice safety profile. See ISO/AAMI/ANSI 10993-18 for information on chemical characterizationof materials.5.2 The following tests should be considered to assessneurotoxicity of medical devices within the scope of this guide.5.2.1 CytotoxicityCytotoxicity assays are sensitivescreening tools that gener

19、ally serve as a starting point forevaluating medical device biocompatibility. See X1.4 forinformation on neuro-cytotoxicity testing.5.2.2 GenotoxicityNervous tissue contains proliferatingcell populations, and can respond to device implantation witha proliferative response. Nervous tissue is also kno

20、wn to giverise to various tumor types. To ensure that medical devices donot include genotoxic chemicals, the use of a panel ofgenotoxicity tests is recommended. The panel of genotoxicitytests should include a test for gene mutation in bacteria, anin-vitro test with cytogenetic evaluation of chromoso

21、mal dam-age with mammalian cells or an in-vitro mouse lymphoma tkassay, and an in-vivo test for chromosomal damage usingrodent hematopoietic cells. See ISO/AAMI/ANSI 10993-3 foradditional information on genotoxicity testing.5.2.3 ImplantationThe use of a clinically relevant implan-tation study is re

22、commended. The implantation site and animalmodel should be selected and justified according to theintended clinical use of the medical device. The study shouldinclude both histopathology and neurobehavioral assessments.In addition to the use of hematoxylin and eosin (H biocompatibility; microglia; m

RATIONALEX1.1 The primary purpose of this guide is to describe a testbattery capable of detecting medical device-

24、mediated neuro-toxicity.X1.2 It is well recognized that the nervous system is aheterogenous tissue comprised of unique cell types, proteins,and biochemical pathways. The interaction of materials withnervous tissue may adversely affect the structure and/or func-tion of the nervous system. The nervous

25、 system has limitedcapacity for repair, increasing the importance of preclinicaldetection of potential neurotoxicants used in medical devices.X1.3 This guide considered the Food and Drug Administra-tion Center for Food Safety and Nutrition Document entitledToxicological Principles for the Safety Ass

27、ytotoxicity testing arenot well established. In addition, as with traditional cytotoxic-ity testing, neuro-cytotoxicity testing can yield false negativeand false positive results. Despite these potential limitations,evaluation of potential medical device neurotoxicity may beimproved by the use of ce

28、ll lines derived from nervous tissuesince these cells are more likely to express nervous tissue-specific toxicant targets. Therefore, consideration should begiven to the inclusion of a neuro-cytotoxicity test in addition totraditional cytotoxicity testing. For additional information onin vitro techn
