To provide medical equipment for properly delivering a cell suspension to a target region by a simple mechanism and an easy operation.SOLUTION: Medical equipment for delivering a cell suspension to a target region includes a hollow shaft body, at least two expandable balloon bodies that are arranged on the shaft body, and a puncture body that is inserted into a blood vessel so as to inject the cell suspension. A blood vessel wall between the at least two expandable balloon bodies is punctured with the puncture body in a direction approximately parallel to the blood vessel wall. Thus, the cell suspension can be injected into the outside of the blood vessel wall.SELECTED DRAWING: Figure 2 【課題】 本発明は、簡便な機構と、簡単な作業で、目的部位に適切に細胞懸濁液を送達するための医療機器を実現することを目的とする。【解決手段】 細胞懸濁液を目的部位に送達するための医療機器であって、中空のシャフト体と、該シャフト体上に配置された少なくとも２つの膨張可能なバルーン体と、血管内を挿通させて細胞懸濁液を注入するための穿刺体とを含み、少なくとも２つの膨張可能なバルーン体の間の血管壁に血管壁と略平行な方向に穿刺体を穿刺することで、血管壁の外側に細胞懸濁液を注入することができる、前記医療機器。【選択図】 図２
