Title
(EN) PROCESS FOR MACHINE REPOSITIONING OF A PRE-CRIMPED DRUG-COATED STENT
(FR) PROCÉDÉ DE REPOSITIONNEMENT DE MACHINE D'UN STENT REVÊTU D'UN MÉDICAMENT PRÉ-SERTI
Abstract
(EN)
The invention relates to a process for repositioning a drug-coated stent (2) that is pre-crimped on a balloon (30) of a balloon catheter (3) extending in an axial direction (z), so that an inner surface (2a) of the stent (2) lies against an outer surface (30b) of the balloon (30), the process having the following steps: Moving the stent (2), by means of at least one contact element (40, 41, 42), in the axial direction (z) with respect to the balloon (30) of the balloon catheter (3), to reposition the stent (2) with respect to the balloon (30), and, to reposition the stent (2), the at least one contact element (40, 41, 42) gripping the stent (2) with a protection device (60, 61, 62; 70) between them, to prevent contact between the stent (2) and the at least one contact element (40, 41, 42).
(FR)
L'invention concerne un procédé de repositionnement d'un stent revêtu de médicament (2) qui est pré-serti sur un ballonnet (30) d'un cathéter à ballonnet (3) s'étendant dans une direction axiale (z), de sorte qu'une surface interne (2a) du stent (2) se trouve contre une surface externe (30b) du ballonnet (30), le procédé comprenant les étapes suivantes : le déplacement du stent (2), au moyen d'au moins un élément de contact (40, 41, 42), dans la direction axiale (z) par rapport au ballonnet (30) du cathéter à ballonnet (3), pour repositionner le stent (2) par rapport au ballonnet (30), et, pour repositionner le stent (2), le ou les éléments de contact (40, 41, 42) saisissant le stent (2) avec un dispositif de protection (60, 61, 62 ; 70) entre eux, pour empêcher le contact entre le stent (2) et le ou les éléments de contact (40, 41, 42).
