A catheter balloon molding system designed to facilitate multi-expansion step balloon forming processes using a segmented mold form. A multi-mating segment (12) of the mold form, defining one end portion of the balloon (11a) , is retained throughout the multiple steps and the parison is kept in place in the multi-mating segment between expansion steps while the mold form is reconfigured for the next expansion step.
L'invention concerne un système de moulage de ballonnets pour cathéter conçu pour faciliter les processus de formation de ballonnets par étapes de dilatation multiples à l'aide d'une forme de moulage segmentée. Un segment (12) à ajustements multiples de la forme de moulage, définissant une partie terminale du ballonnet (11a), est conservé pendant toutes les étapes multiples et la paraison est maintenue en place dans le segment à ajustements multiples entre les étapes de dilatation pendant que la forme de moulage est reconfigurée pour l'étape de dilatation suivante.
