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 iao CE or FDA certification regarding blood compatibility. Who is this standard for?

In vitro blood flow model with physiological wall shear stress for hemocompatibility testing-An example of coronary stent testing. We are specialized in assessing blood compatibility. Inadequate control by kso inhibitors results in pathological processes, such as microthrombi generation or thrombosis, bleeding complications, hemodynamic instability, fever, edema, and organ injury.

Please download Isi or Firefox or view our browser tips. We have developed our own in vitro blood flow model [4] which offers several important advantages: Hemocompatibility of blood contacting medical devices has to be evaluated before their intended application.

Worldwide Standards We can source any standard from anywhere in the world. These responses of blood are due to the natural response of the host defense mechanism against foreign surfaces. To assess hemocompatibility, blood flow models are often used and can either consist of in vivo animal is or in vitro blood flow models.

The standard is applicable to external communicating devices, either with an indirect blood path e. Besides intrinsically driven research we perform basic contract research, which varies from simple hemolysis testing to custom build in vitro blood flow models.

Obstacles in haemocompatibility testing. The model has a low background for thrombosis. Pulsatile flow with physiological wall shear stress. 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. We use cookies to make our website easier to use and to better understand your needs.

Blood compatibility relates to specific interactions between bio materials and circulating blood. This includes a more current description of in vitro techniques that rely less on the use of animals and generate more predictive results.

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? Click to learn more. We offer hemocompatibility testing in accordance with ISO Test laboratories and medical devices manufacturers.

Hemocompatibility testing (ISO )

Selection of tests for interactions with blood Status: 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.

Moreover, we have investigated the necessity of using fresh blood for hemocompatibilty testing [3] and have developed our own in vitro model for hemocompatibilty testing which utilizes pulsatile flow and physiological iao shear stress [4]. Low concentration of anticoagulatns, typically 1. These adverse events can manifest themselves during prolonged and intensive foreign material contact, such as vascular implants and extracorporeal blood circulation.

In recent years it has done so by reviewing literature and identifying the obstacles of hemocompatibility testing [1] and by describing the state-of-the-art blood—biomaterial interface research [2].
