1. A balloon dilation device comprising:
a handle having a proximal end and a distal end;
an inner guide member comprising a proximal portion and a distal portion, wherein the proximal portion of the inner guide member is in the handle, wherein the distal portion of the inner guide member extends distally from the distal end of the handle, wherein the inner guide member comprises a lumen extending from a proximal end of the inner guide member to a distal end of the inner guide member, wherein the distal portion of the inner guide member is malleable such that the distal portion of the inner guide member is configured to be shaped with an angle of 0 degrees to 120 degrees relative to the proximal portion of the inner guide member, wherein the inner guide member is a stainless steel hypotube;
a polymeric shaft mounted about a periphery of the inner guide member; and
an inflatable balloon coupled to the polymeric shaft and disposed about the inner guide member,
wherein the inner guide member has a rigidity that is greater than a rigidity of the polymeric shaft,
wherein a portion of the inner guide member extends distally of a distal end of the polymeric shaft and a distal end of the inflatable balloon, and
wherein the inner guide member has an inner diameter in a range of about 0.508 mm (0.02 inch) to about 1.27 mm (0.05 inch) and a wall thickness between about 0.2032 mm (0.008 inch) to about 0.3048 mm (0.012 inch).
