摘要： A cervical canal dilator having an elongate tubular shaft that defines at least two internal lumens that are juxtaposed to a longitudinal axis. A first inflatable member is positioned on the outer surface of the shaft and is in communication with the first lumen. While a second inflatable member is also positioned on the outer surface of the shaft. The second inflatable, however, is longer than and completely covers the first inflatable member. Additionally, the second member is fabricated of a non-elastic material that limits the inflation of the second member to a predetermined maximum diameter of inflation. The device, also, has a control system which controls the fluids and/or gases that enter the lumens.

摘要： A cervical canal dilating assembly and method of use are shown. The dilator assembly includes a plastic shaft, a first inflatable member, and a second inflatable member. The shaft can range from being rigid to being highly flexible. The second inflatable member is fabricated of a non-elastic material and is configured to have a maximum inflatable diameter. The second inflatable member is configured to have a predetermined maximum inflatable diameter ranging from 4 to 20 mm. The dilating assembly can also be at least partially covered by a sheath. A control system includes means for measuring pressure configured for at least monitoring the pressure of the second inflatable member. A wire can be used in selected configurations to stiffen and shape the shaft. In operation, the initial penetration of the dilating assembly into the uterus uses a wire for increased stiffness. The dilating assembly is then forwarded through the remainder of the cervical canal. The first inflatable member is expanded in the uterus after being uncovered by the sheath. The second inflatable member is positioned in the cervical canal and gradually inflated to a predetermined maximum diameter.
摘要翻译：显示了宫颈管扩张组件及其使用方法。扩张器组件包括塑料轴，第一可膨胀构件和第二可膨胀构件。轴可以从刚性到高度灵活。第二可膨胀构件由非弹性材料制成并且构造成具有最大可充气直径。第二可膨胀构件构造成具有4至20mm范围内的预定最大可充气直径。膨胀组件也可以至少部分地被护套覆盖。控制系统包括用于测量被配置为至少监测第二可充气构件的压力的压力的装置。可以在选定的配置中使用电线来加固和成型轴。在操作中，扩张组件进入子宫的初始穿透使用线来增加刚度。然后将扩张组件通过子宫颈管的其余部分。第一可膨胀构件在被护套覆盖之后在子宫中扩张。第二可膨胀构件定位在子宫颈管中并逐渐膨胀至预定的最大直径。
