  • Patent number: 10265204
    Abstract: Provided is a synthetic resin stent that has resistance to pressure externally applied from the radial direction while in an enlarged diameter state even when the synthetic resin fibers are thin. The synthetic resin stent comprises: a stent main section that is formed by synthetic resin fibers into a cylinder and that can deform from a reduced diameter state to an enlarged diameter state; and a restricting mechanism that keeps the stent main section in the enlarged diameter state by restricting the stent main section from reducing in diameter when in the enlarged diameter state. The synthetic resin stent preferably further comprises a diameter enlarging mechanism that is connected to the stent main section and that deforms the stent main section from a reduced diameter state to an enlarged diameter state.
