Title (EN) Method of Making a Medical Balloon
(FR) PROCÉDÉ DE FABRICATION D'UN BALLONNET MÉDICAL
Abstract:
(EN) A medical balloon (24,30)for a balloon catheter (10)is described. The balloon(30)has at least a first layer (40)made from a first material and a second layer (42)made from a second material, said first (40)and second (42)layers being in overlying relationship with one another and being integral with one another; wherein the first layer (40)has a softening or melting temperature which is higher than a softening or melting temperature of the second layer (42). A method of forming the medical balloon (30)is also described, including locating a raw tubing(131)in a mould(112); preheating and inflating the raw tubing (131)so as to cause it to stretch; heating the raw tubing (131)to soften or melt the second layer(42); setting the inflated raw tubing (131)to form the medical balloon(30); and cooling the set balloon(30).
(FR) La présente invention concerne un ballonnet médical (24, 30) pour un cathéter à ballonnet (10). Le ballonnet (30) comporte au moins une première couche (40) formée à partir d'un premier matériau et une seconde couche (42) formée à partir d'un second matériau, lesdites première (40) et seconde couches (42) étant en relation de superposition mutuelle et étant solidaires. La première couche (40) possède une température de ramollissement ou de fusion qui est supérieure à une température de ramollissement ou de fusion de la seconde couche (42). L'invention concerne également un procédé de fabrication du ballonnet médical (30) comprenant le placement d'un tube brut (131) dans un moule (112); le préchauffage et le gonflage du tube brut (131) pour entraîner son étirement; le durcissement du tube brut (131) gonflé pour former le ballonnet médical (30); et le refroidissement du ballonnet durci (30).
