Modeling Physiological Aortic Flows
Evaluating A Stroke Prevention Device
Pulso technology is currently being used to help cardiologists of a Belgium hospital to investigate the performance of a novel decision-making aid algorithm. The Pulso duplicator is used to reproduce physiological flow and pressures in coronary artery silicone models. Flexible and transparent stenotic models were manufactured by Pulso and used to evaluate the impact of the pathology to the pressure gradient measured to assess the degree of stenosis. FFR and RFR in-vivo like outcomes were reproduced in the bench test.
Physiological Flow Reproduction
Pulso pulse duplicator was programmed to replicate physiological aortic flow signals in the aortic-arch anatomical silicone model. The device allowed to reproduce normal, accelerated and pathological flow conditions. Data collected from the study were used to validate numerical simulations of a stroke prevention device.
Adapted patient flowrate for the model geometry to keep the speed constant (solid line) as well as the flowrate reproduction by the test-bed (dotted line).
