Haemocompatibility of Medical Devices

Medical devices that contact blood during use (e.g. biomaterials, implants) must be haemocompatible. Haemocompatibility can be tested with static or dynamic blood incubation systems depending on the application mode of the medical device.

According to DIN EN ISO 10993-4, tests are grouped into five test categories:

  • Coagulation
  • Platelets
  • Haematology
  • Complement
  • Thrombogenicity

NMI TT provides its expert knowledge to help clients specifying the tests that are needed. Also, NMI TT offers established tests in all test categories and with different incubation systems.

Chandler Loop Method

The Chandler Loop method simulates the circulation of blood by rotating tubes (see picture on the right). The Chandler Loop incubation is the method of choice to test haemocompatibility for medical devices placed into the blood stream.
