摘要：
A catheter for dilating stenotic lesions has an elongated body with at least one lumen extending therethrough. A tip, constructed of materials softer than the elongated body is attached to the distal end of the body. The tip segment has at least one lumen passing therethrough which is in alignment with the lumen in the elongated body. A guide is adapted to pass through the aligned lumens. A balloon is connected to the distal segment of the elongated body over its outer periphery, thereby creating a balloon cavity therebetween. At least one additional lumen is provided in the elongated body in flow communication with the balloon cavity, for selective inflation and deflation thereof, with a contrast fluid.
摘要（中）：
用于扩张狭窄病变的导管具有细长体，其具有延伸穿过其中的至少一个腔。 由比细长体更柔软的材料构成的尖端附接到身体的远端。 尖端段具有通过其中的至少一个腔，其与细长体中的内腔对准。 引导件适于穿过对准的内腔。 气球在其外周边连接到细长主体的远侧部分，从而在它们之间形成球囊腔。 在细长体中提供至少一个另外的腔，其与气囊腔流动连通，用于与对比液一起选择性地充气和放气。
