Significance and Use
The use of in vivo implantation techniques for characterizing the biocompatibility of materials to be utilized in various medical applications provides a unique assessment of such materials not achieved by other procedures. Physical characteristics (that is, form, density, hardness, surface finish) can influence the character of the tissue response to the test materials.
This practice is intended as a rapid screening procedure for determining the acceptability of candidate materials. It would be invoked prior to using the long-term tests described in Practice F981. It is understood that for some applications additional tests, including long-term implantation studies, may be required to assess the final suitability of the candidate materials.
This practice may not be appropriate for all types of implant applications. The user is cautioned to consider the appropriateness of the method in view of the materials being tested, their potential applications, and the recommendations contained in Practice F748.
1.1 This practice provides guidelines for short-term testing or screening of candidate materials, both porous and dense, as to the effects of the material on animal tissue in which it is implanted. This is a rapid screening procedure for determining acceptability of candidate materials.
1.2 This practice, along with other appropriate biological tests (including other appropriate ASTM tests) may be used in the biocompatibility assessment of the candidate materials for use in the fabrication of devices for clinical application.
1.3 This experimental protocol is not designed to provide a comprehensive assessment of the systemic toxicity, carcinogenicity, teratogenicity, or mutagenicity of the material since other standards deal with these issues.
1.4 This practice is one of several developed for the assessment of the biocompatibility of materials. Practice F748 provides guidance for the selection of appropriate methods for testing materials for a specific application.
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
