Abstract
A guidewire lumen for a catheter includes a tubular portion and a sleeve bonded over less than an entire length of the tubular portion. The tubular portion is formed of a first material and the sleeve is formed of a second material. The second material may bond better to certain materials than the first material.
Claims41
A guidewire lumen for a catheter, comprising a tubular portion and a sleeve disposed over less than an entire length 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, and a metallic marker band disposed around a portion of the tubular portion, the sleeve being disposed over 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 method of making a catheter, comprising:
- providing a sleeve over less than an entire length of a tubular portion of a guidewire lumen, the tubular portion being formed of a first material and the sleeve being formed of a second material;
- providing a marker band over the tubular portion and beneath the sleeve;
- and
- bonding the sleeve to a catheter component.
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, 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;
- a balloon bonded to the distal sleeve;
- and
- a catheter shaft bonded to the proximal sleeve.
