    摘要： A lung-volume-reduction elastic implant (500) is tubular and at least the proximal end of the implant has an opening. The implant (500) comprises an elastic deforming part (51) and a flexible guiding part (53) connected to the distal end of the elastic deforming part (51). The elastic deforming part (51) has a shape memory property. The elastic deforming part (51) is provided in the lengthwise direction thereof with several slots (514) at intervals, wherein each slot (514) communicates with the tubular cavity of the elastic deforming part (51). Under the same externally applied force, the flexible guiding part (53) deforms more easily than the elastic deforming part (51). An implant delivering instrument (600) comprises an implant (500) and a matching delivering means (700). The delivering means (700) comprises a core wire (71) and a hollow pushing member (73). The implant (500) is detachably connected to the distal end of the pushing member (73) by means of the proximal end of the implant. The core wire (71) movably passes through the tubular cavity of the implant (500) and the tubular cavity of the pushing member (73).

    摘要： [Task] To provide a stent which can prevent the overall stent from randomly collapsing when expanded, even if the stent is formed of a biodegradable polymer.
    [Means for Resolution] A stent 100 has a configuration which is formed into a cylindrical shape by a linear strut 101. The strut has outer peripheral portions 102 extending around an axial direction of the cylindrical shape and a connection portion 103 connecting the outer peripheral portions to each other in a gap formed by the outer peripheral portions, and has a configuration in which the outer peripheral portions and the connection portion are integrally formed of a biodegradable polymer. In addition, a portion of the strut includes a fragile portion 104 which is more fragile than other different portions of the strut, and in a state where the fragile portion includes a component the same as that of the other portions, the biodegradable polymer itself is fragile.
