Most of the aged illness are apoplexy, heart and cancer. These are caused by diseases of vessels into human body. Interventional radiology is minimally invasive therapy using catheter and very important for keeping of QOL. Stents are used for preventing re-narrowing after expansion of vessel. One is balloon-expandable for vascular, made of stainless steel. Another is self-expandable for non-vascular such as gallbladder, made of Ti-Ni shape memory alloy. The performance of them need flexibility, conformability and positioning. Easy positioning is very important for vascular. Now current stents lacks in some parts of them. Ti-Ni-Nb alloys have the capability of new type stent, self-exapand stent with both excellent mountability and deliverability using new type shape memory alloy.
