A guidewire lumen for a catheter, comprising a tubular portion and a sleeve disposed over less than an entire length of the tubular portion so that the sleeve is not disposed around at least part of the tubular portion, the tubular portion being formed of a first polymer and the sleeve being formed of a second polymer, the second polymer comprising one or more of a polyamide, a nylon, a polyether block amide, and polyurethane.
A guidewire lumen for a catheter, comprising a tubular portion formed of a first material and a sleeve formed of a second material disposed around part of the tubular portion so that the sleeve is not disposed around at least part of the tubular portion, and a metallic marker band disposed around and in direct contact with a portion of the tubular portion, the sleeve being disposed over and in direct contact with the marker band and extending from proximate a distal end of the tubular portion to a point proximal of and proximate the marker band.
A catheter comprising:
- a guidewire lumen comprising a tubular portion and proximal and distal sleeves disposed over less than an entire length of the tubular portion so that the sleeve is not disposed around at least part of the tubular portion, the tubular portion being formed of a first material and the sleeves being formed of a second material, and a metallic marker band disposed between the distal sleeve and the tubular portion and in direct contact with the distal sleeve and the tubular portion;
- a balloon bonded to the distal sleeve;
- and
- a catheter shaft bonded to the proximal sleeve.
