Summary:To provide a medical wire which is adapted for a relatively thin tubular tissue.SOLUTION: A medical wire 20 is moved forward and rearward in a tubular catheter 10, in use, a tip 26 of the medical wire 20 is expanded from the catheter 10, thereby restoring from a first shape when it is stored in the catheter 10 to a second shape which is a shape before the tip is stored in the catheter 10, and when the tip is stored again in the catheter 10, the shape of the tip is deformed from the second shape to the first shape, the tip has a shape memory performance. The second shape is a shape extended to a direction crossing a longitudinal axis of the medical wire 20.SELECTED DRAWING: Figure 1 【課題】比較的細い管状組織にも適合する医療用ワイヤを提供する。【解決手段】管状のカテーテル１０内を進退させて使用する医療用ワイヤ２０であって、医療用ワイヤ２０の先端部２６は、カテーテル１０から展開することにより、カテーテル１０に収納されているときの第１形状から、カテーテル１０に収納する前の第２形状へと復帰可能で、かつ、カテーテル１０内に再度収納することにより、第２形状から第１形状へと変形可能な形状記憶性能を有する。第２形状は、医療用ワイヤ２０の長手軸線と交差する方向に拡張した形状である。【選択図】図１
