A cylindrical balloon for medical tubes, which is susceptible to bending operations, comprises a low stretchable section formed, by a partial cross-linking treatment, on the balloon along the circumferential direction thereof. A medical tube equipped with a balloon comprises a shaft tube for being inserted into a living body, a cylindrical balloon liquid-tightly connected to the shaft tube at the periphery on the tip thereof, a first lumen which is formed within the shaft tube and which communicates with the interior of the balloon, and at least one second lumen which is formed within the shaft tube and which is opened at the tip of the shaft tube; or comprises a shaft tube which is inserted into a living body, a cylindrical balloon, one end of which is liquid-tightly connected to the shaft tube at the tip thereof, a long tool for medical treatments or for diagnoses, whose tip portion is liquid-tightly connected to the other end of the balloon directly or indirectly, and a lumen which is formed within the shaft tube and communicates with the interior of the balloon so that a liquid can pass through the balloon and which accommodates the long tool for medical treatments or for diagnoses, wherein the cylindrical balloon is the same as that defined above.
一种用于医疗管的圆柱形球囊,可进行弯曲操作,包括通过部分交联处理在球囊上沿其圆周方向形成的低伸展部分。装有球囊的医疗管包括一个用于插入活体的轴管、一个在其顶端外围与轴管液密连接的圆柱形球囊、一个在轴管内形成并与球囊内部相通的第一管腔,以及至少一个在轴管内形成并在轴管顶端开口的第二管腔;或包括一个插入活体内的轴管、一个圆柱形球囊(其一端在顶端与轴管液体紧固连接)、一个用于医疗或诊断的长工具(其顶端部分与球囊另一端直接或间接液体紧固连接),以及一个在轴管内形成并与球囊内部相通以便液体能通过球囊并容纳用于医疗或诊断的长工具的管腔,其中圆柱形球囊与上述定义的相同。
