Abstract

On décrit un ballonnet gonflable et un cathéter destinés à être insérés dans un conduit corporel. Le cathéter (10) comporte un axe (12) qui porte un ballonnet (24) gonflable par un lumen (14) central disposé dans l'axe et chargé d'envoyer un fluide de gonflage. Ce ballonnet est fabriqué en une combinaison d'un élastomère thermoplastique, de préférence un élastomère thermoplastique technique, et d'un matériau polymère structurel non docile, cette combinaison se présentant éventuellement sous forme d'un mélange. Une autre possibilité de combinaison peut donner un ballonnet en couches doté par exemple d'une couche polymère structurelle interne qui est non docile et d'une couche élastomère externe douce et résistante à l'abrasion. On décrit aussi des procédés qui permettent de fabriquer un tel ballonnet en une combinaison d'un élastomère thermoplastique et d'un matériau polymère structurel non docile.
