Biocompatibility is one of the most critical performance studies that manufacturers need to perform as part of their product development process. ISO 10993-5 and ISO 10993-10 are FDA-recognized standards for biocompatibility. Whether you perform these studies in-house or send out samples to a third-party lab the protocol for biocompatibility assessment must be conducted in accordance with ISO 10993.
13 types of biological effects must be tested depending on the body contacting device:1
- Material-Mediated Pyrogenicity
- Subacute/Subchronic Toxicity
- Chronic Toxicity
- Reproductive/Developmental Toxicity
When deciding which type of biological effect needs to be tested the following factors must be considered:1
- Nature of body contact of the product, which depends on the category of the product and the body contacting surface, such as
- Surface devices that could have contact with intact skin, mucosal membrane, breached or compromised surface.
- External communicating devices that could have contact with blood path, tissue, bone, dentin, or circulating blood and
- Implantable devices that could have contact with tissue, bone, or blood.
- Contact duration of the device with the surfaces mentioned above. The contact duration as per ISO 10993 is defined as limited duration which is ≤24 hours, prolonged duration which is >24 hours to 30 days, and devices that are permanently in contact with the body surface which is > 30 days.
Whether you are in the product development stage or conducting these tests for a pre-market submission, determining which tests to conduct can always seem confusing, but EMMA International is always there to assist you in all of your product development and regulatory needs.
