For example, comprehensive technical documentation is required and proof of biological safety (biocompatibility) is a prerequisite for the approval of your medical devices.<\/p>\n

For this reason, NIUTEC develops test strategies in accordance with ISO 10993-12, ISO 10993-15 and ISO 10993-18 with subsequent toxicological evaluation in accordance with ISO 10993-17.[\/vc_column_text][vc_empty_space height=”40px”][\/vc_column_inner][\/vc_row_inner][\/vc_column][vc_column width=”1\/4″][\/vc_column][\/vc_row][vc_row full_width=”stretch_row” css=”.vc_custom_1581513658950{background-color: #ededed !important;}”][vc_column width=”1\/4″][\/vc_column][vc_column width=”1\/2″][vc_column_text]\n

Which substances does your product release?<\/h2>\n[\/vc_column_text][vc_column_text]The ISO 10993 series of standards requires reliable residue detection of process auxiliaries. This concerns material-specific additives or breakdown products that can be released during the use of medical devices and pose a health risk. A toxicological evaluation confirms the biocompatibility of your medical product.<\/p>\n

With this approach, you can at best avoid animal testing.[\/vc_column_text][gt3_spacing height=”25px”][vc_column_text]\n

    Extraction procedures in accordance
    \nwith ISO 10993-12<\/h2>\n[\/vc_column_text][vc_column_text]For the biocompatibility evidence in accordance with ISO 10993, various extraction procedures are used (ISO 10993-12 or -15), whereby so-called extractables and leachables are released. These extracts resulting from the extraction process allow the analysis and detection of a wide range of possible residues (ISO 10993-18). The exact substance identification is the basis for risk assessments and toxicological findings (ISO 10993-17).[\/vc_column_text][gt3_spacing height=”25px”][vc_column_text]\n

    Extractables and leachables in accordance
    \nwith ISO 10993-18<\/h2>\n[\/vc_column_text][vc_column_text]Extractables and leachables are substances which are differentiated according to organic or inorganic residues. In the case of organic residues, the substances are further differentiated according to their volatility \u2013 from volatile organic compounds (VOC) to semi-volatile organic compounds(SVOC) or non-volatile organic compounds(NVOC).<\/p>\n

    The substances released by the extraction process are examined using specific analytical methods that allow a wide range of substance classes to be covered.[\/vc_column_text][vc_column_text]In accordance with ISO 10993-18, the following analytical methods are particularly recommended:<\/strong><\/p>\n

      \n
    • Gas Chromatography \u2013 Mass Spectrometry GC-MS<\/li>\n
    • Head-Space-Gas Chromatography \u2013 Mass Spectrometry HS-GC-MS<\/li>\n
    • Liquid Chromatography \u2013 Mass Spectrometry LC-MS<\/li>\n
    • Ion Chromatography IC<\/li>\n
    • Inductively Coupled Plasma \u2013 Mass Spectrometry ICP-MS<\/li>\n
    • Fourier Transform Infrared Spectrometry FTIR<\/li>\n
    • Total Organic Carbon TOC<\/li>\n
    • Gravimetry<\/li>\n<\/ul>\n[\/vc_column_text][vc_column_text]\n

      Biologocal testing in accordance
      \nwith ISO 10993<\/h2>\n[\/vc_column_text][vc_column_text]A distinction is made between in vitro and in vivo test procedures for the biological testing of medical devices in accordance with ISO 10993. The following test procedures are used for approval:<\/p>\n
        \n
      • ISO 10993-3
        \nTests for genotoxicity, carcinogenicity and reproductive toxicity<\/li>\n
      • ISO 10993-4
        \nSelection of tests for interaction with blood<\/li>\n
      • ISO 10993-5
        \nTests for in vitro cytotoxicity<\/li>\n
      • ISO 10993-6
        \nTests for local effects after implantation<\/li>\n
      • ISO 10993-10
        \nTests for irritation and skin sensitisation<\/li>\n
      • ISO 10993-11
        \nTests for systemic toxicity<\/li>\n<\/ul>\n
