(57) [Abstract] [Purpose] To provide a stent having excellent biocompatibility, particularly antithrombogenicity, and less risk of restenosis. A stent characterized in that a coating layer made of a porous tetrafluoroethylene resin film is provided on the inner and outer surfaces of a tubular structure made of an elastic wire. A tubular membrane of a tetrafluoroethylene resin porous body is placed on the inner and outer surfaces of a tubular structure made of elastic wire, and partial heat fusion between the inner and outer tubular membranes is performed. A method for manufacturing a characteristic stent. A method for producing a stent, characterized in that the tubular membranes are partially bonded together by heating and pressure via a thermoplastic resin. |
