An intravascular thrombus capturing instrument is disclosed comprising a wire body inserted into a catheter and retractable from the tip of the catheter, and a thrombus capturing part fitted at the tip of the wire body. The thrombus capturing part includes a fixed section fitted at the tip of the wire body, a stopper secured to the wire body at prescribed intervals from the fixed section, a slidable section slidably provided around the wire body posterior to the stopper, and an elastic coil bridging between the fixed section and the slidable section. This securely captures and removes embolus such as thrombus clung to a vascular wall.
