CATHETER HAVING TRANSITIONING SHAFT SEGMENTS

摘要

Method of forming a balloon catheter includes providing 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 method also includes coupling a distal end section to a distal end of the inner tubular member and having a proximal end and a distal end. The method also includes coupling a proximal end of a balloon to the distal portion of the outer tubular member, and coupling a distal portion of the balloon to the distal end section. The balloon has a working length between the proximal end and the distal end. The balloon defines an inner chamber. The proximal end of the distal end section is disposed within the inner chamber.

1. A method of forming a balloon catheter comprising:
providing 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 inner tubular member; coupling a distal end section to a distal end of the inner tubular member, the distal end section having a proximal end and a distal end; and coupling a proximal portion of a balloon to the distal portion of the outer tubular member, and coupling a distal portion of the balloon to the distal end section, the balloon having a working length between the proximal portion and the distal portion, 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.
