This Part replaces the following historical editions. — GB/T 16886.1-2001; GB/T 16886.1-1997. Introduction The primary aim of this Part of GB/T 16886 / ISO 10993 is to protect humans from potential biological risks arising from the use of medical devices. This Part is compiled from numerous International and National Standards and Guidelines concerning the biological evaluation of medical devices. It is intended to be a guiding document for the biological evaluation of medical devices for risk management process (as part of overall evaluation and development process for various medical devices). This approach combines the review and evaluation of existing data from all sources with, where necessary, the selection and application of additional trial, so that to perform holistic biological evaluation to the usage safety of various medical devices. It must be appreciated that the term “medical device” has wide-ranging meaning, it may be consisted of a single material which may be existed in more than one physical form, it may also be consisted of complex instruments which are consisted of multiple components or apparatus components made of multiple materials. GB/T 16886 / ISO 10993 addresses the determination of the effects of medical devices on tissues, under general condition, it does not involve device of special application. Thus, for a complete biological safety evaluation, it classifies medical devices according to the nature and duration of their anticipated contact with human tissues when in use. It indicates, in matrices, the biological data sets that need to be considered by various medical devices. The range of biological hazards is wide and complex. When considering the mutual interaction between tissue and composing material, it cannot be isolated from the overall device design. Thus, in designing a device, choosing the best material with respect to its tissue interaction may not necessarily result good performance of device, the interaction between tissue and material is only one of the characteristics to be considered in making that choice. When implementing device’s function, biological evaluation must involve the mutual interaction between the material prediction and tissue. Tissue interactions refer to the adverse reaction caused by a material under the specific application, it might not occur un other applications. Biological trial is usually based upon in-vitro and semi-vivo trial methods and animal models, it cannot unequivocally conclude that the same reaction will also occur in human body. Therefore, it can only be shown in the form of caution to judge the predicted effect when the device is used in human body. In addition, different individuals may respond differently to the same material, it indicates that some patients can have adverse reactions even to well-established materials. The role of this Part is to provide framework for planning biological evaluation of medical device. Along with the scientific knowledge advancement and understanding of the basic mechanisms of tissue responses, under the conditions that it is possible to obtain the same relevant information as in-vivo model, it shall preferably adopt chemical analysis trial and in-vitro model, so as the quantity of tested animals is minimized. GB/T 16886 / ISO 10993 do not intent to rigidly specify a set of test methods, including pass/fail criteria. As this might result in 2 possibilities. One of the possibilities is that development and application of new medical device may be unnecessarily restrained, another possibility is that a false sense of security may be generated by using the medical device.
