PROBLEM TO BE SOLVED: To provide a compact and easy-to-operate contrast agent removing device for efficiently removing a contrast agent in blood vessels and also to provide a contrast agent removing method.SOLUTION: A contrast agent removing device 10 configured to remove a contrast agent in blood vessels comprises: a shaft part 20 having a distal-side lumen 21 formed in a distal part thereof; a pump 50 mounted inside the distal-side lumen 21 and capable of suctioning an outside fluid through a distal-side opening part 24 of the distal-side lumen 21; a recovery part 30 capable of selectively recovering the contrast agent from the fluid pressurized by the pump 50 within the distal-side lumen 21; and a fluid return part 35 for returning the fluid from which the contrast agent has been removed by the recovery part 30, from the shaft part 20 to the outside.SELECTED DRAWING: Figure 2【課題】コンパクトな構成で操作が容易であり、造影剤を血管内から効果的に除去できる造影剤除去デバイスおよび造影剤除去方法を提供する。【解決手段】造影剤を血管内から除去するための造影剤除去デバイス10であって、遠位部に遠位側ルーメン21が形成されたシャフト部20と、遠位側ルーメン21内に配置されて遠位側ルーメン21の遠位側開口部24から外部の流体を吸引可能なポンプ50と、遠位側ルーメン21内でポンプ50により加圧された流体から造影剤を選択的に回収可能な回収部30と、回収部30により造影剤を取り除かれた液体をシャフト部20から外部へ戻す返液部35と、を有する。【選択図】図2
