Key result
Heparin coatings improve blood parameters versus uncoated materials in simulated cardiopulmonary bypass models.
Why the study?
In vitro evaluation of blood-device interactions uses various models with differing complexity, and the degree to which findings from simple and complex models complement each other was unclear.
Population
Human blood-material/device interactions in vitro using two models
Comparison
Surface modifications (Carmeda BioActive Surface and Duraflo II heparin coatings) vs unmodified materials
Design
Comparative study of simple multipass loop model and simulated cardiopulmonary bypass model

Simple in vitro models complement complex ones for blood-device testing; leaves open optimal model selection pending further validation.
Simple multipass loop models and complex simulated cardiopulmonary bypass models provide complementary and consistent findings for evaluating blood-device interactions, such as the benefits of heparin coatings.
Münch et al. (2000) studied Blood-material/device interactions. Heparin coatings (Carmeda BioActive Surface and Duraflo II) vs. Uncoated materials was evaluated on Blood parameters (coagulation, platelets, hematology, immunology). A simple multipass loop model and a complex simulated cardiopulmonary bypass model produced complementary findings, both demonstrating favorable blood parameter responses with heparin coatings.
