| Research Abstract |
We have developed paediatric myocardial and circulatory assist systems as an alternative surgical treatment for congenital heart diseases. A covalent-type anisotropic Ni-Ti alloy fibre was employed as the actuator for the totally-implantable circulatory assist system which could be clinically applied for small sized patients. Subsequently, the two types of assisted circulation system, a) a contractile extra cardiac conduit for Fontan procedures, and b) a ventricular pouch support system were implemented based on the hemodynamic and thermodynamic control.
