Title
(EN) PROLATE SPHEROID-SHAPED BALLOON
(FR) BALLONNET EN FORME DE SPHÉROÏDE APLATI
Abstract
(EN) A balloon system is disclosed for positioning a distal end of a catheter at a treatment site. The system includes an elongated catheter shaft that is formed with a lumen and a tubular shaped balloon membrane that is made of a compliant material. For the system, the proximal and distal ends of the balloon membrane are affixed to an outer surface of the shaft to establish an inflation chamber between the balloon membrane and the outer surface of the shaft. The balloon membrane can have a non-uniform thickness between the proximal and distal ends of the membrane to establish a selected membrane shape when the balloon is inflated. For example, the selected membrane shape can be a prolate spheroid. With this arrangement, a relatively short and a relatively flat inter-contact surface in the midway region of the membrane is obtained when the balloon is inflated.
(FR) L'invention concerne un système de ballonnet pour positionner une extrémité distale d'un cathéter au niveau d'un site de traitement. Le système comprend une tige de cathéter allongée qui est pourvue d'une lumière, et une membrane de ballonnet de forme tubulaire qui est constituée d'un matériau conforme. Pour le système, les extrémités proximale et distale de la membrane de ballonnet sont fixées à une surface extérieure de la tige pour établir une chambre de gonflage entre la membrane de ballonnet et la surface extérieure de la tige. La membrane de ballonnet peut avoir une épaisseur non-uniforme entre les extrémités proximale et distale de la membrane pour établir une forme de membrane sélectionnée lorsque le ballonnet est gonflé. Par exemple, la forme de membrane sélectionnée peut être un sphéroïde aplati. Avec cet agencement, une surface de contact intermédiaire relativement plate et relativement courte dans la région centrale de la membrane est obtenue lorsque le ballonnet est gonflé.
