Patent ID: 8142394

Claim:
An enteral feeding catheter assembly comprising: a catheter having a proximal end, a distal end, and catheter walls defining a catheter lumen; 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 located at a distal end of the catheter, an inflation valve located on the base, the inflation valve in fluid communication with the balloon through an inflation lumen defined by the catheter walls; an internal cavity defined in the base, the cavity in fluid communication with the inflatable balloon such that fluid used to inflate the balloon to an operational fill volume fills the internal cavity as well; and a translucent window over the internal cavity such that an interior volume of the internal cavity is externally viewable; wherein introduction of a colored fluid to pressurize the balloon results in the colored fluid in the internal cavity, thereby providing an externally visual indication of the inflation state of the balloon.
