Abstract:
1. A catheter comprising: a monolithic hypotube defining a proximal shaft member 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; 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 monolithic hypotube, the inflation lumen of the midshaft member configured to receive at least a portion of the distal section of the monolithic hypotube, wherein at least a portion of the distal section of the hypotube is disposed within the inflation lumen of the midshaft member, with the inflation lumen of the hypotube in fluid communication with the inflation lumen of the midshaft member; a distal tubular shaft member extending distally from the midshaft member, the distal tubular shaft member having a guidewire lumen and an inflation lumen defined therein, 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, wherein the first angled cut extends distally beyond the midshaft member into the distal tubular shaft member; and a balloon coupled to the distal tubular shaft member and in fluid communication with the inflation lumen of the distal tubular shaft member.
