导管、导管制造用模具、导管的制造方法
摘要：
导管具有：外侧管；内侧管，其设置于所述外侧管的内侧；以及分支部，其在第一端部侧分离所述外侧管与所述内侧管，至少在所述外侧管的内侧和所述内侧管的外侧形成的第一管腔的截面积与在所述内侧管内形成的第二管腔的截面积之比(第一管腔的截面积/第二管腔的截面积)被设定为，在所述外侧管和所述内侧管延伸的长度方向上，所述分支部中的所述外侧管与所述内侧管的截面积比是与所述内侧管配置于所述外侧管内的状态下的所述第一管腔与所述第二管腔的截面积比的值相同或比它高的值。
摘要（英）：

This catheter includes an outer tube, an inner tube provided inside the outer tube, and a branched part that separates the outer tube and the inner tube at a first end side. The ratio of the cross-sectional area of a second lumen defined within the inner tube to the cross-sectional area of a first lumen defined at least by the inside of the outer tube and the outside of the inner tube (cross-sectional area of the first lumen/cross-sectional area of the second lumen) is set so that the ratio of the cross-sectional areas of the outer tube and the inner tube at the branched part is equal to or greater than the value of the ratio of the cross-sectional areas of the first lumen and the second lumen when the inner tube is arranged inside the outer tube in a longitudinal direction in which the outer tube and the inner tube extend.
