Balloon Dilation Devices, Methods of Use, and Methods of Manufacture

A balloon dilation device, comprising:

• a handle having a proximal handle end and a distal handle end;
• a shaft extending distally from the distal handle end, wherein the shaft comprises:
• a hypotube comprising an inner surface and an outer surface, wherein the inner surface defines a lumen of the hypotube,
• a liner tube disposed within the lumen of the hypotube, wherein a distal end of the liner tube is distal of a distal end of the hypotube and defines an atraumatic tip of the shaft, and
• a position sensor coupled to a distal portion of the hypotube, wherein the position sensor is between the inner surface of the hypotube and the liner tube;
• and
• an inflatable balloon disposed about at least a portion of a distal portion of the shaft.
