<p>It is intended to provide a stent which can be surely inserted into a deep part of an obstructed or contracted tubular organ and exerts a dilation force therein while sustaining its flexibility. A stent (1) having a plurality of circular units (10, 20), each consisting of a linear part (11) extending in a zigzag manner toward the peripheral direction and being joint to form circles, and a joining part (40) whereby adjacent ones of these circular units are joined together in the axial direction. A definite circular unit (20) has an X-ray impermeable marker (30) fixed at an intermediate position in the peripheral direction between a folded part (13) of the above-described linear part (11) and the next folded part (13) thereof.</p> |
