Catheter having transitioning shaft segments
First Claim
1. A balloon catheter comprising:
- an elongate tubular shaft including an outer tubular member 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 outer tubular member, 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; 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 outer tubular member, 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 inner tubular member comprises a trilayer tubular member, and the proximal end of the distal end section is disposed within the inner chamber.

Abstract
Balloon catheter includes an elongate tubular shaft having an outer tubular member having proximal and distal portions, and an inner tubular member having a distal length extending distally from the distal portion of the outer tubular member. The elongate tubular shaft has an inflation lumen and a guidewire lumen defined therein. The guidewire lumen extends along at least the distal length of inner tubular member. The balloon catheter also includes a distal end section coupled to a distal end of the inner tubular member and having a proximal end and a distal end. The balloon catheter also includes a balloon having a proximal portion sealingly coupled to the distal portion of the outer tubular member, a distal portion sealingly coupled to the distal end section, and a working length therebetween. The balloon defines an inner chamber. The proximal end of the distal end section is disposed within the inner chamber.
