摘要：
A balloon catheter device includes a catheter having a proximal end, a distal end, and catheter walls defining a catheter lumen. An inflatable balloon is located at a distal end of the catheter and is inflated through an inflation valve located on a base. An internal cavity is defined in the base and is in fluid communication with the inflatable balloon. A translucent window is disposed over the internal cavity such that an interior volume of the cavity is externally viewable. Introduction of a colored fluid through the inflation valve to inflate the balloon results in the colored fluid also being present in the internal cavity, thereby providing an externally visual indication of the inflation state of the balloon.
