Title
(EN) A BALLOON FOR CATHETERS AND RELATED PRODUCTION PROCESS
(FR) BALLONNET POUR CATHÉTERS ET PROCÉDÉ DE FABRICATION ASSOCIÉ
Abstract
(EN)
A balloon (10) for an angioplasty catheter expandable by means of a pressurized inflation liquid comprises at least one wall portion (12) provided with passageways (16) for diffusing an active agent conveyed by the aforesaid pressurized liquid. The passageways (16) are provided with obturators (18) that can be opened under the pressure exerted by the pressurized liquid, the obturators being in the form of convex septa with convexity facing radially outwardly being frangible under the pressure of the pressurized liquid.
(FR)
L'invention porte sur un ballonnet (10) pour un cathéter d'angioplastie dilatable au moyen d'un liquide de gonflage pressurisé. Ledit ballonnet comporte au moins une partie de paroi (12) pourvue de passages (16) pour diffuser un agent actif transporté par le liquide pressurisé susmentionné. Les passages (16) sont pourvus d'obturateurs (18) qui peuvent être ouverts sous la pression exercée par le liquide pressurisé, par exemple sous la forme de cloisons frangibles sous la pression du liquide pressurisé.
