< Topic > Although the tube of the organism is supported, it designates that the lumen professional thesis which is suited sufficiently is offered as topic.Solutions Lumen professional thesis, paralleling to length direction axis (504), has the tube shape itself which extends, that tube shape itself, includes the plural meandering condition sections (506a, 506b and 506c) which extend abbreviation lap according to direction, state and the development which connect the meandering condition section which one to which each of those meandering condition sections, the main extending resident in section includes with the bend (512) which, connects the arm which it adjoins with the arm (510) which possesses the specified width which is crossed, possesses the main extending resident in section bridge (514a and 514b) adjoins at least, can wither lumen professional thesisThe bend which is faced to the meandering condition section which it adjoins the state namely ru which is done in both parties of a state where it is developed, lap has slipped with turning direction vis-a-vis the bend of opposite side of the meandering condition section which it adjoins, one which connects the meandering condition section which it adjoins bridge extends, abbreviation at least, straightly at the same time, main length direction of bigger value than width of the arm has possessed the width which is crossed.【課題】 生体の管を支持するのに十分適した内腔プロテーゼを提供することを課題とする。【解決手段】 内腔プロテーゼは、長さ方向軸線(504)に沿って延びた筒状本体を有し、その筒状本体は、略周方向に沿って延びた複数の蛇行状部(506a,506b,506c)を含み、それら蛇行状部の各々が、その主たる延在部と交差する所定幅を有するアーム(510)と、隣接したアームを接続している湾曲部(512)とを含み、主たる延在部を有する少なくとも一つのブリッジ(514a,514b)が隣接した蛇行状部を接続し、内腔プロテーゼがしぼめられた状態及び展開された状態即ち或る程度展開された状態の双方において、隣接した蛇行状部に向いている湾曲部が、隣接した蛇行状部の反対側の湾曲部に対して周回り方向でずれており、隣接した蛇行状部を接続している少なくとも一つのブリッジが、略まっすぐに延び、且つアームの幅よりも大きな値の、主たる長さ方向と交差する幅を有している。
