Abstract
A rapid exchange dilation catheter having an elongated tubular shaft section with a guidewire port for entry of a guidewire into said distal section at an exchange joint. A stiffening wire is positioned within the elongated tubular shaft with its distal end anchored approximate the exchange joint and its proximal end freely floating within the proximal section of the catheter.
Claims8
A catheter comprising;
- an elongated tubular shaft comprising a distal section and a proximal section, said tubular shaft defining a guidewire port between said proximal section and said distal section for entry of a guidewire into said distal section;
- and
- a stiffening wire positioned within said elongated tubular shaft and having a distal portion anchored within said tubular shaft distal section and a free proximal end extending into said tubular shaft proximal section.
A catheter having a proximal end and a distal end, said catheter comprising:
- an elongated tubular shaft having a guide wire port for entry of a guidewire;
- a balloon attached to the catheter distal end;
- a guidewire tube defining a guidewire lumen extending within said tubular shaft from said guidewire port to said distal end of said catheter,
- an exchange joint located adjacent said guidewire port, said guidewire tube being bonded to said tubular shaft to retain said guidewire tube relative to said tubular shaft at said exchange joint, with a space between said guidewire tube and tubular shaft providing an inflation lumen for said balloon, and
- a stiffening wire positioned within said tubular shaft, said stiffening wire secured at said exchange joint and having a free proximal end extending towards said proximal shaft end.
