What is EN ISO 10993-16:2021?

EN ISO 10993-16:2021 is a professional technical standard that focuses on the biological evaluation of medical devices. This standard provides specific guidance on selecting appropriate tests and evaluating the potential risk of medical devices that come into direct or indirect contact with the human urinary system. By following the guidelines set out in EN ISO 10993-16:2021, manufacturers can ensure that their urinary medical devices are safe and reliable for use.

Scope and Application

EN ISO 10993-16:2021 applies to all medical devices intended to come into contact with the human urinary system. This includes devices such as urinary catheters, stents, urine collection bags, and other similar products. The standard provides detailed instructions on the biological evaluation of these devices to assess the risks associated with their use. It covers both short-term and long-term exposure scenarios, ensuring that the devices meet the necessary safety requirements throughout their intended lifespan.

Testing Methods

To comply with EN ISO 10993-16:2021, manufacturers must perform a series of tests to evaluate the biocompatibility of their urinary medical devices. These tests include cytotoxicity testing, sensitization testing, irritation or intracutaneous reactivity testing, genotoxicity testing, and systemic toxicity testing. The standard also addresses concerns related to the risk of infection and pyrogenicity, providing specific test methods for assessing these aspects. By conducting these tests, manufacturers can identify any potential risks associated with their devices and take appropriate measures to mitigate them.

Documentation and Evaluation

One of the key requirements of EN ISO 10993-16:2021 is proper documentation and evaluation of the biological safety of urinary medical devices. Manufacturers must keep detailed records of all testing procedures, results, and conclusions. This documentation serves as evidence of compliance with the standard and can be reviewed by regulatory bodies or other stakeholders. It is important for manufacturers to demonstrate that they have followed the guidelines outlined in EN ISO 10993-16:2021 and have taken necessary steps to ensure the safety of their products.
