Title
(EN) NON-COEXTRUSION METHOD OF MAKING MULTI-LAYER ANGIOPLASTY BALLOONS
(FR) PROCEDE DE FABRICATION SANS CO-EXTRUSION DE BALLONNETS D'ANGIOPLASTIE A COUCHES MULTIPLES
Abstract
(EN)
A non-coextrusion process for making multi-layer angioplasty balloons involves pre-forming separate parisons (10, 12) and then concentrically disposing the plural parisons to form a composite parison which is then subjected to a blow-molding process. The resulting balloon can have its properties tailored by appropriate selection of the particular plastics to be used for the multiple parisons.
(FR)
Un procédé sans co-extrusion servant à fabriquer des ballonnets d'angioplastie à couches multiples consiste à former préalablement des paraisons séparées (10, 12) et à placer concentriquement ces paraisons, de manière à obtenir une paraison composite qu'on soumet ensuite à une opération de soufflage. La sélection appropriée des plastiques utilisés pour les paraisons multiples permet de personnaliser les propriétés du ballonnet obtenu.
