MEDICAL DEVICE BIOLOGICAL EVALUATION

Biocompatibility testing evaluates the compatibility of medical devices with a biological system and is an important element of biological risk assessment. It investigates how the device interacts with the many types of live tissues and cells exposed to it when it comes into touch with patients.

  • The toxicological assessments and the selection of device materials to be tested should take into consideration thorough characterization of all manufacturing materials.

  • The device’s manufacturing materials, end product, and potentially leachable chemicals or degradation products should all be examined for their impact on the device’s overall toxicological assessment.

  • The bioavailability of the substance should be considered in the tests used in the toxicological evaluation (i.e., nature, degree, frequency, duration and conditions of exposure of the device to the body).

  • Any in vitro or in vivo research or testing should follow established Good Laboratory Practice guidelines (GLP).

  • Unless testing is done pursuant to recognised standard that does not require data submission, the whole experimental data should be given to the reviewing body.

  • Any change in the device’s chemical composition, manufacturing method, physical configuration, or intended usage should be assessed for potential toxicological consequences and the need for further toxicity testing.

  • For an overall safety assessment, the toxicological examination done in line with this advice should be evaluated in connection with additional information from non-clinical testing, clinical trials, and post-market experiences.

BIOCOMPATABLITY TEST

It’s critical to determine whether your product contains toxins or has the potential to cause harm. Our team of medical device regulatory experts along with lab toxicologist collaborate with you plan the biocompatablity test identification and also helps with any justification if required.

Bacterial reverse mutation (Ames) test – Genotoxicity

Chromosomal aberration test – Genotoxicity

Hemocompatibility: Partial thromboplastin time – PTT

Hemocompatibility: (Platelets and Leucocytes)
