Abstract
Ballonnets à usage médical, notamment pour cathéters d'angioplastie, réalisés à partir de certains élastomères thermoplastiques de copolymère bloc, ce copolymère étant constitué de segments durs d'un polyester ou d'un polyamide et de segments mous d'un polyéther; les segments durs de polyester sont des polyesters d'un acide dicarboxylic aromatique et d'un diol C¿2?-C¿4?; les segments durs de polyamide sont des polyamides d'acides carboxyliques C¿6? ou plus et de diamines organiques C¿6? ou plus, ou d'acides aliphatiques .omega.-amino-.alpha.C¿6? ou plus, et les segments souples de polyéther sont des polyéthers de diols C¿2?-C¿10?; le copolymère bloc présente un module de flexion faible, à savoir inférieur à 150,000 psi; le copolymère bloc présente une dureté, sur l'échelle D de Shore, supérieure à 60; et le pourcentage en poids du polymère bloc attribuable aux segments durs se situe entre environ 50 et 95 %. Ces polymères permettent d'obtenir des ballonnets très résistants, à paroi mince, élastiques ou semi-élastiques, et donc des cathéters de faible section. Ces catheter de faible section présentent une bonne aptitude à la pénétration, une bonne maniabilité et une bonne aptitude à la réutilisation après un premier gonflage.
