1. A medical balloon catheter, comprising:
an elongate metal alloy tube, said tube comprising
a proximal alloy tube end,a distal alloy tube end,a polymer barrier coating thermoformed around the tube, anddefining a fluid-patent longitudinal alloy tube lumen portion extending between the proximal and distal alloy tube ends; a dual-lumen polymer tube comprising
a proximal polymer tube end attached directly to the polymer barrier coating adjacent the distal alloy tube end,a distal polymer tube end,a first lumen configured as a fluid-patent polymer tube inflation lumen that extends distally from, and is in patent fluid communication with, the alloy tube lumen, anda second lumen configured as a wire guide lumen extending parallel to the first lumen with a wire guide aperture immediately adjacent the proximal polymer tube end; an inflatable balloon directly attached to the distal polymer tube end such that a lumen of the balloon is in fluid communication with the first lumen; where the alloy tube lumen and the first lumen together comprise a substantially patent path of fluid communication between the alloy tube end and the balloon lumen; and where the second lumen forms a fluid-patent path of mechanical communication for a wire guide, which extends from a wire guide aperture near the proximal polymer tube end through the balloon lumen to a distal end of the balloon. |
