  • Publication number: 20230138256
    Abstract: Provided is a stent that can improve the property of storage in a delivery system. This stent 1 is formed by a linear member in a tubular shape having a plurality of openings, extends in an axial direction J, and is deformable from a reduced diameter state to an expanded diameter state. The stent 1 is formed by connecting a plurality of polygonal annular parts 2 formed in a polygonal annular shape when viewed in the axial direction J side by side in the axial direction J of the stent 1 in a state of being bent or curved in the axial direction J. The linear members constituting the polygonal annular parts 2 adjacent to each other in the axial direction J each have a through-hole 23 penetrated in the axial direction J and are connected by a joining member 3 penetrating the two through-holes 23.

  • Publication number: 20220211524
    Abstract: A synthetic resin stent is able to demonstrate self-extensibility, restorability, adhesion to the digestive tract, and ability to follow peristaltic movement. The synthetic resin stent is provided with: a first stent that has a first stent body formed as a cylindrical mesh from fibers made of synthetic resin, and that can be deformed from a reduced-diameter state to an expanded-diameter state; and a second stent that is formed as a cylindrical mesh which is finer than that of the first stent body, is arranged so as to cover the outer periphery of the first stent body, and can be deformed from a reduced-diameter state to an expanded-diameter state.

  • Publication number: 20220183866
    Abstract: A stent can ensure storability in thin tubular members such as delivery systems and is insusceptible to positional displacement after placement of the stent in an affected part of a bodily conduit. This synthetic resin comprises a tubular first braid component comprising a plurality of fibers that are braided into a net-like form, and a second braid component comprising a plurality of fibers that are disposed braided into the first braid component to form an annular shape. The first braid component includes a plurality of first fibers, a plurality of second fibers, and a plurality of first intersections. The second braid component includes a plurality of wave-like third fibers disposed separated in an axial direction and a plurality of wave-like fourth fibers disposed separated in the axial direction. At least one of the first intersections is disposed in an intersection region surrounded by the third fiber and the fourth fiber.

  • 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.
