Abstract
Un élément de cathéter intravasculaire à faible friction est constitué d'une matrice de polyester dans laquelle est incorporé un granulé fin et glissant comprenant de préférence une ou plusieurs particules glissantes appropriées choisies dans le groupe consistant en graphite, disulfure de molybdène, TiC, MoC, difluorure de graphite et des fluoropolymères. Ce polyester est de préférence un copolymère contenant une quantité prédominante de térephtalate de polybutylène et de moindres quantités de composants telles que du polytétraméthylène éther glycol qui a été estérifié avec un téréphtalate de diméthyle, de l'HYTREL? par exemple. Avec ce matériau à faible friction on fabrique généralement des éléments tubulaires internes ou externes de cathéters de dilatation à fil fixe ou entourant le fil. En plus de ce granulé glissant, ou peut incorporer dans cette matrice un fluide à base de polysiloxane.
