摘要：
A catheter assembly incorporating a pre-biased indicator, the assembly includes a catheter having a proximal end, a distal end, and catheter walls defining a catheter lumen. The assembly further includes a base located at the proximal end of the catheter, the base defining an opening to the catheter lumen, the base having a first end and a second end. An inflatable balloon having a predetermined fill volume is located at a distal end of the catheter. An inflation valve is located on the base; the inflation valve is in fluid communication with the balloon through an inflation lumen defined by the catheter walls. The pre-biased indicator located on the base in fluid communication with the balloon is configured to provide a discrete visual signal that the pressure of a fluid in the balloon is different from a predetermined level of pressure or the volume of the balloon is different from the predetermined fill volume.
摘要（中）：
包括预偏置指示器的导管组件，该组件包括具有限定导管内腔的近端，远端和导管壁的导管。 组件还包括位于导管近端的底座，底座限定了导管内腔的开口，底座具有第一端和第二端。 具有预定填充体积的可膨胀气囊位于导管的远端。 充气阀位于底座上; 充气阀通过由导管壁限定的充气腔与气囊流体连通。 位于与球囊流体连通的基座上的预偏置指示器被配置为提供离散的视觉信号，即球囊中的流体的压力与预定的压力水平不同或气囊的体积不同于 预定填充量。
