摘要： The present invention relates to catheters and like devices for passage into a body cavity.In the invention the device has a stem portion comprising at least a first tube disposed within a second tube, the tubes being joined at one pair of ends by a flexible member covering the opening of the passage formed between the inner tube and the outer tube. The flexible member is arranged such that the tubes are movable relative to each other and by movement of the inner tube away from or towards the one end of the outer tube the flexible member respectively either can be drawn within the adjacent one end of the outer tube to be enclosed within the outer tube or pushed outside the adjacent one end of the outer tube to expose a balloon. The balloon can be inflated within the body cavity using a fluid under pressure supplied to the balloon from outside the body through said passage.This is a continuation of application Ser. No. 918,506, filed Oct. 14, 1986, now abandoned, which is a continuation of Ser. No. 617,998, filed May 31, 1984, now abandoned.
摘要翻译：本发明涉及用于通入体腔的导管和类似装置。在本发明中，该装置具有至少包括设置在第二管内的第一管的杆部分，该管通过覆盖形成在内管和外管之间的通道的开口的柔性部件在一对端连接。柔性构件布置成使得管能够相对于彼此移动并且通过内管远离或朝向外管的一端的移动，柔性构件分别可以在外管的相邻一端内被拉伸封闭在外管内或者被推到外管的相邻一端外露以露出气球。气球可以在体腔内使用从身体外部通过所述通道供应到气囊的压力下的液体充气。这是应用程序的延续。 1986年10月14日提交的第918,506号现在已经放弃，这是Ser的延续。 1984年5月31日提交的第617,998号，现已放弃。
