The shape memory polymer can be deformed at more than glass transition temperature. It can maintain its shape after it has turned into less than glass transition temperature. Then it can return to the original shape after being heated again at more than glass transition temperature. Utilizing these characteristics, the objective of this study is to develop a tube-shaped micro dilatation manipulator of a 1-mm inside diameter and a 100-mm length. The manipulator suggested here is the one with a heater placed on a shape memory polymer tube. When it is generated by heater, the parts where it surpasses glass transition temperature will be dilated due to inside pressure and cause the tube to bend to a curve. The shape can be maintained after decreasing the temperature while maintaining the inside pressure. The shape can return to the original shape after it is regenerated at more than glass transition temperature. First, we revealed the deformation condition of the tube of the suggested micro dilatation manipulator after having analyzed the tube deformation by the Finite Element Method. Next, we discussed the process of manufacturing a tube and a heater.
