1. A catheter comprising:
an elongate tubular shaft having a proximal portion and a distal portion, the elongate tubular shaft including an inner tubular member having a distal length extending distally from the distal portion of the elongate tubular shaft, the elongate tubular shaft having an inflation lumen and a guidewire lumen defined therein, the guidewire lumen extending along at least the distal length of the inner tubular member;
a distal tip member having a proximal end and a distal end, wherein the distal tip member is monolithic and the proximal end of the distal tip member is secured to a distal end of the inner tubular member, the distal tip member having a guidewire lumen in communication with the guidewire lumen of the inner tubular member; and
a balloon having a proximal cone section, a distal cone section and a working length between the proximal cone section and the distal cone section, a proximal portion of the balloon sealingly coupled to the distal portion of the elongate tubular shaft and a distal portion of the balloon sealingly coupled to the distal tip member, the balloon defining an inner chamber in fluid communication with the inflation lumen;
wherein the proximal end of the distal tip member is disposed within the inner chamber along the working length of the balloon, and further wherein the distal tip member has a generally cylindrical configuration with uniform diameter and wall thickness.
