Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process"
Guidance for Industry and Food and Drug Administration Staff
Document issued on: September 4, 2020
The draft of this document was issued on April 23, 2013.
This document supersedes “Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process"” dated June 16, 2016.
Introduction
FDA has developed this guidance document to assist industry in preparing Premarket Applications (PMAs), Humanitarian Device Exceptions (HDEs), Investigational Device Exemption (IDE) Applications, Premarket Notifications (510(k)s), and De Novo requests for medical devices that come into direct contact or indirect contact with the human body1 in order to determine the potential for an unacceptable adverse biological response resulting from contact of the component materials of the device with the body. The purpose of this guidance is to provide further clarification and updated information on the use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process" to support applications to FDA. This guidance replaces Office of Device Evaluation (ODE) Blue Book Memorandum #G95-1 (1995), entitled “Use of International Standard ISO-10993, ‘Biological Evaluation of Medical Devices - Part 1: Evaluation and Testing.’” This guidance document also incorporates several new considerations, including the use of risk-based approaches to determine if biocompatibility testing is needed, chemical assessment recommendations, and recommendations for biocompatibility test article preparation for devices with submicron or nanotechnology components and for devices made from in situ polymerizing and/or absorbable materials, which were not previously discussed in G95-1.
When assessing new devices, the sponsor should specifically state if the device does not have any direct or indirect tissue contact,2 and no further biocompatibility information would be needed.
When assessing device modifications, the sponsor should specifically state if the modification does not result in a change to any direct or indirect tissue-contacting components, and no further biocompatibility information would typically be needed. However, if the change could affect other parts of the device with direct or indirect contact that were not changed, a biocompatibility evaluation should be conducted to assess the potential impact of the change. For example, if a new non-contact internal component is added, but it requires the application of heat in order to join to another component that has patient contact, the patient-contacting component may be impacted by the application of heat such that biocompatibility could be impacted, and should be assessed.
