Abstract

L'invention concerne un cathéter intravasculaire (10) qui possède une combinaison de caractéristiques: de plus grandes souplesse, douceur et radio-opacité et une meilleure résistance à l'ovalisation et au vrillage. La région proximale (14) d'un arbre (12) comprend une couche polymère interne lubrifiante (26), une couche de renfort (32) et une couche externe (30). La couche de renfort (32) peut comprendre une tresse comportant deux ou plusieurs composants métalliques (42) et plusieurs filaments uniques (41), de préférence en LCP. Les éléments polymères de la tresse assurent une meilleure souplesse et une plus grande douceur, en plus d'une pression d'éclatement plus élevée. Les éléments métalliques de la tresse assurent une plus grande radio-opacité et une meilleure résistance à l'ovalisation et au vrillage. Le cathéter (10) peut aussi comprendre un ou plusieurs éléments axiaux disposés entre les éléments hélicoïdaux formant la tresse. Les éléments axiaux (34) offrent un certain nombre d'avantages, y compris le maintien de la correspondance un pour un lors des manipulations axiales, le maintien d'une flexibilité uniforme dans plusieurs plans de flexion, la réduction des risques d'un effet d'enroulement, l'augmentation uniforme de la rigidité du cathéter et l'augmentation de la pression d'éclatement.
