Abstract:
A balloon expandable superelastic stent is made of a Ti—Ni—Nb (the content of Nb being at least 3 at %) shape memory alloy. A shape recovery temperature of the stent is lower than a living body temperature in an unloaded state after shape memory treatment. The shape recovery temperature exceeds the living body temperature after the stent is mounted to a catheter and released from the catheter in a living body.
