Claim Text:
1. A catheter comprising: a hypotube defining a first lumen and having proximal and distal ends, and proximal, intermediate, and distal portions disposed between the proximal and distal ends; an inflation tube with distal and proximal ends, wherein the proximal end of the inflation tube is bonded to the intermediate portion of the hypotube and a portion of the inflation tube is disposed over the distal portion of the hypotube such that the portion of the inflation tube overlaps the distal portion of the hypotube, forming a second lumen therebetween; and a guidewire tube with a proximal end, a distal end, and an outer surface extending from the proximal end to the distal end, the proximal end forming a guidewire port, the guidewire tube extending through an opening in the hypotube and distally through the hypotube, forming a guidewire lumen; wherein the second lumen extends radially outward from an outer surface of the distal portion of the hypotube to an inner surface of the portion of the inflation tube overlapping the distal portion of the hypotube.
