Abstract
Balloon assemblies and valves for balloons have improved inflation capabilities. The inlet ends of the balloon valves are disrupted either with a slit or a portion of material removal to prevent the inlet end from being folded back into the valve passageway during insertion of an inflation probe. With the inlet end slit, the slit portions are readily folded back by the inflation probe, thus preventing potential blockage of the valve inlet.
