PROBLEM TO BE SOLVED: To provide a medical appliance that enables an embolus state of a blood vessel near target tissue to be determined from the upstream side of the blood vessel with respect to a site of embolization, and a method for detecting hemodynamics.SOLUTION: A medical appliance comprises a linear member capable of being inserted through a blood vessel, and a sensor that is attached to the linear member so as to detect a predetermined physical property value enabling the determination of the embolus state on the downstream side of the blood vessel.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2019,JPO&INPIT【課題】標的組織の近傍の血管の塞栓状態を、塞栓部位よりも血管の上流側から判別可能とする医療器具及び血行動態を検出するための方法を提供する。【解決手段】医療器具は、血管内を挿通可能な線状部材と、前記線状部材に取り付けられ、前記血管の下流側の塞栓状態を判別可能な所定の物性値を検出するセンサと、を備える。【選択図】図2
