ISO 10993

The ISO 10993 set entails a series of standards for evaluating the biocompatibility of medical devices to manage biological risk. These documents were preceded by the Tripartite agreement and is a part of the international harmonisation of the safe use evaluation of medical devices.[1] For the purpose of the ISO 10993 family of standards, biocompatibility is defined as the "ability of a medical device or material to perform with an appropriate host response in a specific application".

ISO 10993-1:2009 & FDA endpoints for consideration

The following table provides a framework for the development of a biocompatibility evaluation. Different biological endpoints may require evaluation for particular medical devices, including either additional or fewer endpoints than indicated. If it is unclear in which category a device falls, consulting device-specific guidances or contacting the appropriate US Food and Drug Administration (FDA) review division for more information is possible. The table "Endpoints to be addressed in a biological risk assessment" was revised by the 2018 edition of ISO 10993-1. The selection of endpoints for the biocompatibility evaluation is determined by the nature of body contact (e.g. implant device) and contact duration (e.g. long term contact of more than 30 days).
