Summary:To provide means capable of readily recognize a rotation posture about an axis line of a catheter in a radiographic video picture.SOLUTION: A catheter 10 includes: a shaft 11 having a cylindrical blade tube 31 through which a radiation ray is transmitted; and markers 61, 62 positioned in the blade tube 31 and having a radiation transmissivity which is different from the blade tube 31. Respective markers 61, 62 are positioned while not overlapping on each other in an axial direction 101 and a circumferential direction 102.SELECTED DRAWING: Figure 3 【課題】放射線撮影された映像において、カテーテルの軸線周りの回転姿勢を容易に認識可能な手段を提供する。【解決手段】カテーテル１０は、放射線が透過する円筒形状のブレードチューブ３１を有するシャフト１１と、ブレードチューブ３１に位置しており、ブレードチューブ３１と放射線の透過性が異なるマーカー６１、６２とを備えている。各マーカー６１、６２は、軸線方向１０１及び周方向１０２において相互に重複しない位置にある。【選択図】図３
