Abstract:

Provided is a stent of a novel structure with which deflection of the line-shaped body during expansion is prevented and a substantially uniform expansion is achieved over the entire length thereof, and with which, after implantation, stent fracture and damage of somatic tissue can be prevented by the stent exhibiting a superior pliability and conforming to the shape of the somatic lumen. A stent (10) having a cylindrical peripheral wall (12) and in which the peripheral wall (12) is formed by a line-shaped body (14) that extends in a helical shape in the circumferential direction while traversing back and forth in the axial direction with a prescribed amplitude. In the stent, connecting parts (22), which connect portions of the line-shaped body (14) that are adjacent in the axial direction, are formed and are provided with friable parts (24), which are ruptured by implantation in a somatic lumen and release the connections due to the connecting parts (22).
