Patent ID: 8657782

Claim:
A balloon 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 end section coupled to a distal end of the inner tubular member, the distal end section having a proximal end and a distal end, wherein the distal end section includes a distal inner member having a proximal end and a distal end, and a distal tip member having a proximal end and a distal end, the proximal end of the distal inner member coupled to the distal end of the inner tubular member and the proximal end of the distal tip member coupled to the distal end of the distal inner member; and a balloon having a proximal portion, a distal portion and a working length therebetween, the proximal portion of the balloon sealingly coupled to the distal portion of the elongate tubular shaft, the distal portion of the balloon sealingly coupled to the distal end section, the balloon defining an inner chamber in fluid communication with the inflation lumen; wherein the proximal end of the distal end section is disposed within the inner chamber.
