<p>PROBLEM TO BE SOLVED: To provide a novel fundamental structure for preventing the excess growth and the restenosis of a cell due to the excess stimulus of a healthy tissue near a lesion part by the both ends of a cylinder of the indwelled state to the lesion part in a lumen dilation indwelling implement of a coiled state or a cylindrical state. SOLUTION: The lumen dilation indwelling implement comprises a lumen dilation indwelling unit 1A of a first embodiment constituted in a pulpy structure more easily radially reduced at both ends 3 of the longitudinal direction of a cylinder than an intermediate part 2 with the entire length having a substantially equal diameter and a lumen dilation indwelling unit 1B of a second embodiment constituted in a 'barrel type cylinder' formed in a maximum diameter of the cylinder at the center and radially reduced at the end in the longitudinal direction of the cylinder.</p> |
