Abstract
A double-tube type stent is inserted into a hollow tubular organ such as a bile duct so as to relieve narrowing of the bile duct on, for instance, an anastomotic area of the intrahepatic bile duct of a liver transplant patient. A hollow cylindrical body has a plurality of rhombic spaces formed by weaving a superelastic shape-memory-alloy wire so as to be crossed. A silicon coating layer is coated on an outer surface of the cylindrical body using a silicon solution. A polytetrafluoroethylene (PTFE) tube is fixedly fitted around the cylindrical body having the silicon coating layer leaving a gap therebetween.
