Abstract

L'invention concerne un ballonnet médical de dilatation à double couche qui comprend une couche intérieure contenant un polymère choisi dans le groupe constitué d'un polyester, d'un polyéther, d'un polyamide et de leurs copolymères et une couche extérieure qui contient un polyamide. Éventuellement, ce ballonnet à double couche comprend également un stent monté sur le ballonnet. Le stent est éventuellement un stent d'élution de médicaments. Un procédé permettant de former un ballonnet de dilatation à double couche consiste à former un extrudat à double couche constitué d'une couche extérieure contenant un polyamide et une couche intérieure contenant un polymère choisi dans le groupe constitué d'un polyester, d'un polyéther, d'un polyamide et de leurs copolymères. Le procédé consiste également à former le ballonnet à double couche à partir de l'extrudant à double couche dans une machine de formation de ballonnets. Le ballonnet présente une force de rétention d'environ 10.000 à environ 60.000 p.s.i.
