A hybrid in silico-in vitro cardiorespiratory simulator for medical device testing

Cardiovascular medical devices (CMDs) (e.g. artificial hearts, ventricular assist devices, ECMO, heart valves) support the cardiac and/or the respiratory function of patients. Large challenges are encountered when assessing CMDs interaction with the human body and the effects on the heart and vessels. Especially CMDs with new designs require an extensive evaluation concerning their effectiveness and safety under different pathophysiological conditions. We propose a high fidelity cardiorespiratory simulator for the testing of the hemodynamic performance of CMDs. The proposed simulator merges the flexibility of the in silico system with a hydraulic interface to test CMDs. As such, the simulator embeds a high fidelity cardiorespiratory model, allowing the reproduction of pathologies at both cardiac and respiratory level. The simulator works as a test bench for the assessment of CMDs, from prototype stage to pre-clinical stage. Thanks to its flexibility and high-fidelity, the simulator helps reducing animal testing and provides insights on how to improve CMD design to better suit different patient’s needs.

Helpathon #12 – Can you help Erica?

We are inviting Dutch-speaking citizens from all walks of life to join a unique Helpathon and help Erica van Oort, coordinator of the Animal-Free Transition Program (TPI) in the Netherlands. No prior knowledge of animal testing is required—your fresh perspective can help Erica communicate more effectively about animal-free research. We strongly believe that well-informed citizens are key to improving democratic policy-making on health research, with and without animals. Please share this invitation to at least one suitable person who could contribute—and of course, you are warmly welcome to join as well.

VHP4Safety project

The safety testing of chemicals and pharmaceuticals traditionally relies on animal studies. However, these raise ethical concerns and often fail to accurately predict human responses. New scientific developments offer opportunities to build a Virtual Human Platform (VHP) for safety assessment, a platform that enables assessment based solely on human physiology and biology, integrating data from in vitro and in silico models. This video explains how we are developing the VHP through an interdisciplinary approach. Read the paper in the videolink or visit or VHP4Safety (https://vhp4safety.nl/) for more information.
