This document replaces GB/T 16886.1-2011 "Biological evaluation of medical devices
- Part 1: Evaluation and testing within a risk management process". Compared with
GB/T 16886.1-2011, in addition to structural adjustment and editorial changes, the main
technical changes are as follows:
a) Add the scope of applicability and inapplicability for carrying out biological
hazard assessment (see Clause 1);
b) Add some terms and definitions used in GB/T 16886 (see Clause 3);
c) Add nanomaterial (see 3.15, 4.3, 6.1, 6.3.2, 6.3.2.13, 6.3.2.14, 6.3.2.15, B.3.1.2,
B.4.1.4) and absorbable material evaluation information (see B.4.3.3 and B.4.4.2);
d) Add biological evaluation procedures for medical devices [see 4.1 a)];
e) Add the content of the overall biological evaluation of medical devices [see 4.3
c)];
f) Add biological safety assessment requirements for "whole life-cycle of a medical
device" and "re-usable medical devices" (see 4.7 and 4.8);
g) Change the "Summary of the systematic approach to a biological evaluation of
medical devices as part of a risk management process" (see Figure 1; Figure 1 of
the 2011 edition);
h) Add requirements for biological risk assessment of commercially-marketed
medical devices when the edition of this document is updated (see 4.11);
i) Add the evaluation information of "Non-contacting medical devices" (see 5.2.1)
and the evaluation information of "Transitory-contacting medical devices" (see
5.3.2);
j) Change the description of medical devices that contact tissue, bone or pulp/dentin
systems [see 5.2.3 b); 5.2.2 b) of the 2011 edition];
k) Add "Gap analysis and selection of biological endpoints for assessment" (see 6.2);
l) Add procedures to be considered in selecting biological testing [see 5) in item b)
of 6.3.1];
m) Add requirements for acute systemic toxicity test or risk assessment (see 6.3.2.6);
n) Add the principle of using animal tests for biological endpoint studies (see 6.3.2.9);
o) Change the situation of considering biodegradation tests (see 6.3.2.13; 6.2.2.13 of
the 2011 edition);
Biological evaluation of medical devices - Part 1:
Evaluation and testing within a risk management process
1 Scope
This document specifies:
- the general principles governing the biological evaluation of medical devices
within a risk management process;
- the general categorization of medical devices based on the nature and duration of
their contact with the body;
- the evaluation of existing relevant data from all sources;
- the identification of gaps in the available data set on the basis of a risk analysis;
- the identification of additional data sets necessary to analyse the biological safety
of the medical device;
- the assessment of the biological safety of the medical device.
This document applies to evaluation of materials and medical devices that are expected
to have direct or indirect contact with:
- the patient's body during intended use;
- the user’s body, if the medical device is intended for protection (e.g., surgical
gloves, masks and others).
This document is applicable to biological evaluation of all types of medical devices
including active, non-active, implantable and non-implantable medical devices.
This document also gives guidelines for the assessment of biological hazards arising
from:
- risks, such as changes to the medical device over time, as a part of the overall
biological safety assessment;
- breakage of a medical device or medical device component which exposes body
tissue to new or novel materials.
Other parts of GB/T 16886 cover specific aspects of biological assessments and related
tests. Device-specific or product standards address mechanical testing.
This document excludes hazards related to bacteria, fungi, yeasts, viruses, transmissible
spongiform encephalopathy (TSE) agents and other pathogens.
