Abstract

Fontan procedure is one of the common surgical treatment of congenital heart diseases. Patients with Fontan circulation have single ventricle in the systemic circulation with the total cavopulmonary connection. Pulmonary blood flow in the Fontan circulation is lower than in healthy subjects, and the central venous pressure may elevate. In this study, we developed a mechanical circulatory assist device for the extracardiac conduit for Fontan circulation and examined its driving method in the mock pediatric pulmonary circulatory system. We used shape memory alloy (SMA) fiber as an actuator of the device. The SMA actuator wrapped the extracardiac conduit between inferior vena cava and pulmonary artery. We designed two different types of the circulatory assist devices. We drove these devices in two different modes by the synchronized and sequential motions. The flow volume was 10mL/min against a load of 10mmHg, and the maximum contractile force indicated 60mmHg in the mock test. These results suggested the effective mechanical assistance for Fontan pulmonary circulation.
