This invention relates to a dilatation balloon formed from an extruded tubular preform by blowing, said balloon having a body, at least one cone and at least one waist portion wherein said balloon has a lubricity coating gradient from the body portion which has the lowest coat thickness to the waist portion which has the highest coat thickness said coating applied to said extruded tubular preform prior to forming said balloon by blowing.
La présente invention concerne un ballonnet de dilatation réalisé par soufflage à partir d'une avant-forme tubulaire extrudée. Ce ballonnet comporte un corps, au moins un cône, et au moins une zone resserrée. En outre, le ballonnet présente un gradient de revêtement lubrifiant partant de la partie du corps dont l'épaisseur de revêtement est la plus faible et aboutissant à la zone resserrée où l'épaisseur de revêtement est la plus élevée. En l'occurrence, ce revêtement est appliqué sur l'avant-forme tubulaire extrudée avant le formage du ballonnet par soufflage.
