Abstract
<p>We have been developing a dynamic flow regulation clip for Fontan circulation to eliminate backflow during the exhalation phase in the patients with congenital heart failure. The clip has been designed to increase hydrodynamic resistance through the bypass from the inferior vena cava to pulmonary artery during the respiration. The mechanism of the resistance change is to be controlled from outside of the graft by the contraction of shape memory alloy fibers. In this study, we developed a mock circulation system simulating backflow of Fontan circulation using a linear actuation mechanism for respiratory hydrodynamic pressure changes. Consequently, it was suggested that the control parameter and the resistance values of Fontan regulation clip could be obtained.</p>
