Hemocompatibility testing (ISO )

Use of fresh human blood 10993–4 30 minutes after blood withdrawal. In vitro blood flow model with physiological wall shear stress for hemocompatibility testing-An example of coronary stent testing. Obstacles in haemocompatibility testing. We have developed our own in vitro blood flow model [4] which offers several important advantages: Blood compatibility relates to specific interactions between bio materials and circulating blood.

Biological evaluation of medical devices—Part 4: In this system all relevant aspects of blood activation are taken into consideration, but, and this is most important, testing should simulate clinical conditions as much as possible. The standard is applicable to external communicating devices, either with an indirect blood path e. Application of biomaterials in direct blood contact results in activation of the blood coagulation system 100993-4 in an inflammatory 19093-4.


The version was updated to match the current tools and techniques used to evaluate medical device blood material interactions.

This includes a more current description of in vitro techniques that rely less on the use of animals and generate more predictive results. Overview Product Details What is this standard about? As one of our experts, Dr Wim van Oeveren, is a member of the ISO committee that drafts and revises the ISO standard, we are very well qualified to help you perform hemocompatibility testing to achieve CE or FDA certification regarding blood compatibility.

These adverse events can manifest themselves during prolonged and intensive foreign material contact, such as vascular implants and extracorporeal blood circulation.

Selection of tests for interactions with blood Status: The model has a low background for thrombosis. These responses of blood are due to the natural response of the host defense mechanism against foreign surfaces. Hemocompatibility of blood contacting medical devices has to be evaluated before their intended application.

Basic research Still having a strong connection with academia, HaemoScan is committed to advancing the Blood-Biomaterial interface research and hemocompatibility testing.

Why should you use this standard? Given the disadvantages of animal models, such as higher costs, more variability, more time consuming, and insensitivity due to overwhelming short-term effects of tissue injury, in vitro blood flow models are more attractive.

It is a specification stating general requirements for evaluating the interactions of medical devices with blood. To assess hemocompatibility, blood flow models are often used and can either consist of in vivo animal models or in vitro blood flow models.
