Patent

CA 2470024

A guide catheter has properties that promote enhanced visibility of the guide catheter using fluoroscopic or ultrasonic imaging techniques. The tip of the guide catheter may incorporate a material that is both fluoro and echo visible. The first material also may be provided in various amounts along the length of the guide catheter. In addition, the guide catheter may incorporate a reinforcing braid that includes one or more strands of a second material that is radio-opaque. As a result, the result guide catheter achieves improved radio-opacity and echogenicity.

L'invention concerne un cathéter guide dont les propriétés permettent une visibilité améliorée de ce cathéter au moyen de techniques d'imagerie fluoroscopique ou ultrasonore. L'embout du cathéter guide peut incorporer un matériau à la fois fluorescent et visible par échographie. Le premier matériau peut aussi être disposé dans des quantités variables le long du cathéter guide. La cathéter guide peut, en outre, comprendre une tresse renforçante comprenant un ou plusieurs brins d'un second matériau radio-opaque. En conséquence, ce cathéter guide possède une radio-opacité ainsi qu'une échogénicité améliorées.
