摘要： Provided is a stent of a novel structure with which deflection of a line-shaped body during expansion is prevented and a substantially uniform expansion is achieved over an entire length thereof, and with which, after implantation, stent fracture and damage of body tissue can be prevented by the stent exhibiting a superior pliability and conformability to a shape of a somatic lumen. A stent having a cylindrical peripheral wall formed with a line-shaped body that extends in a helical form in a circumferential direction while reciprocating in an axial direction at a given amplitude. In the stent, connecting parts are formed to link portions of the line-shaped body that are adjacent in the axial direction, and a friable part is provided to rupture itself by being implanted in the somatic lumen and release a link made by the connecting parts.

摘要： A stent includes a plurality of wavy annular bodies each formed in an annular shape from a wavy linear member, and a connection part provided between the adjacent wavy annular bodies, interconnecting the adjacent wavy annular bodies coaxially, weaker than the wavy annular bodies and rupturable. The connection part extends in a slanting manner relative to an axial direction in which the wavy annular bodies are aligned, and interconnects that one inflexed part of one wavy annular body which is curved in a shape projected toward the other wavy annular body adjacent to the one wavy annular body and that the other inflexed part of the other wavy annular body which is curved in a shape projected toward the one wavy annular body.
