Zusammenfassung:	To provide a catheter for medical solution injection capable of injecting a medical solution to an object tissue from a blood vessel and improving efficiency of procedures in medical solution injection.SOLUTION: A catheter includes a shaft. The shaft includes a first lumen for sucking a part of a biological tissue from a first opening formed on a side face of the shaft by making a pressure of the inside negative, and a second lumen for causing a puncture needle inserted into the second lumen to protrude from a second opening formed on the side face of the shaft.SELECTED DRAWING: Figure 1 【課題】血管内から対象組織に薬液を注入することを可能とし、かつ、薬液注入における手技の効率を向上させることが可能な薬液注入用のカテーテルを提供する。【解決手段】カテーテルは、シャフトを有し、そのシャフトは、第１ルーメンであって、内部を陰圧にすることにより、シャフトの側面に形成された第１開口から生体組織の一部分を吸引する第１ルーメンと、第２ルーメンであって、シャフトの側面に形成された第２開口から、第２ルーメンに挿通された穿刺針を突出させる第２ルーメンと、を備える。【選択図】図１
