To provide a medical device which can reduce puncture resistance while partitioning a plurality of lumens extending in an axial direction.SOLUTION: A medical device includes a cylindrical part which partitions an inner lumen positioned in the inside in a radial direction and an outer lumen positioned in the outside in the radial direction in the inside, and the cylindrical part has a tapered surface whose diameter is reduced to be close to the inside in the radial direction toward a distal end side on its side surface. A first distal end opening of the inner lumen is formed on a distal end surface of the cylindrical part, and a second distal end opening of the outer lumen is formed on the tapered surface of the cylindrical part.SELECTED DRAWING: Figure 4 【課題】軸方向に延在する複数のルーメンを区画しつつ、穿刺抵抗を低減できる医療器具を提供する。【解決手段】医療器具は、径方向の内側に位置する内側ルーメン、及び、径方向の外側に位置する外側ルーメン、を内部に区画する筒部を備え、前記筒部の側面は、前記遠位端側に向かうにつれて径方向の内側に近づくように縮径するテーパ面を備え、前記内側ルーメンの第１先端開口は、前記筒部の先端面に形成されており、前記外側ルーメンの第２先端開口は、前記筒部の前記テーパ面に形成されている。【選択図】図４
