A dilation catheter for dilation of an anatomical passageway includes a luer member, an elongate shaft, and an inflatable dilator. The luer member comprises at least one fluid port. The luer member is rotatably disposed about the elongate shaft such that the luer member is configured to rotate relative to the elongate shaft about the longitudinal axis of the elongate shaft. The elongate shaft comprises a first lumen. The at least one fluid port is in fluid communication with the first lumen such that fluid may be passed through the at least one fluid port into the first lumen. The inflatable dilator is positioned along a length of the elongate shaft. The inflatable dilator is in fluid communication with the first lumen such that the inflatable dilator is inflatable by fluid passed through the at least one fluid port and into the first lumen.
