Abstract
To provide a stent which holds various performances such as deliverability, prevention of restenosis, flexible shape conformability, and so on and is therefore adaptable not only to a bile duct but also to a blood vessel system such as a tortuous coronary artery substantially without causing restenosis. A stent with an autonomic function is made of a Ti—Ni based shape memory alloy and has a maximum expanding force at a center portion in its lengthwise direction.
