Claim:
1. A catheter comprising: a hypotube having a proximal section and a distal section with an inflation lumen and a longitudinal axis defined therethrough, the distal section having a skive defined by a first angled cut, an axial cut, and a second angled cut, wherein the first angled cut extends at a first angle relative the longitudinal axis that is not perpendicular thereto, the second angled cut extends at a second angle relative the longitudinal axis that is not perpendicular thereto, and the axial cut is substantially parallel to the longitudinal axis; a midshaft member including a guidewire lumen and an inflation lumen defined therethrough, the inflation lumen of the midshaft member in fluid communication with the inflation lumen of the hypotube, the inflation lumen of the midshaft member configured to receive at least a portion of the distal section of the hypotube; a distal tubular shaft member extending distally from the midshaft member, the distal tubular shaft member comprising an outer tubular member and an inner tubular member disposed within the outer tubular member, wherein the inner tubular member extends from the midshaft member and has a guidewire lumen defined therein, the outer tubular member extends from the midshaft member and defines an inflation lumen between the outer tubular member and the inner tubular member, the guidewire lumen of the distal tubular shaft member in fluid communication with the guidewire lumen of the midshaft member, the inflation lumen of the distal tubular shaft member in fluid communication with the inflation lumen of the midshaft member; and a balloon coupled to the distal tubular shaft member and in fluid communication with the inflation lumen of the distal tubular shaft.
