Title
(EN) SHAPE ADAPTABLE MULTI-LAYERED INTRA-SACCULAR FLOW REDUCTION DEVICE AND METHODS OF MANUFACTURING SAME
(FR) DISPOSITIF DE RÉDUCTION DE FLUX INTRA-SACCULAIRE MULTI-COUCHE CONFORMABLE ET SES PROCÉDÉS DE FABRICATION
Abstract
(EN)
A vaso-occlusive device having a delivery configuration when restrained within a delivery catheter and having a deployed configuration when released from the delivery catheter into an aneurysmal sac is provided, the device comprising a tubular structure including a distal portion configured for expanding within the aneurysmal sac when distally deployed from the delivery catheter into the aneurysmal sac, a proximal portion configured for inverting and expanding into the expanded distal portion when distally deployed from the delivery catheter, thereby creating multi-layer scaffolding within the aneurysmal sac, and an inflection region between the distal portion and the proximal portion, wherein the inflection region is configured for urging the inversion of the proximal portion into the expanded distal portion.
(FR)
L'invention concerne un dispositif vaso-occlusif ayant une configuration de mise en place lorsqu'il est retenu à l'intérieur d'un cathéter de mise en place et ayant une configuration déployée lorsqu'il est libéré du cathéter de mise en place dans un sac anévrismal, le dispositif comprenant une structure tubulaire comprenant une partie distale conçue pour se déployer à l'intérieur du sac anévrismal lorsqu'elle est déployée de manière distale à partir du cathéter de mise en place dans le sac anévrismal, une partie proximale conçue pour s'inverser et se déployer dans la partie distale déployée lorsqu'elle est déployée de manière distale à partir du cathéter de mise en place, créant ainsi un échafaudage multicouche à l'intérieur du sac anévrismal, et une région d'inflexion entre la partie distale et la partie proximale, la région d'inflexion étant conçue pour pousser l'inversion de la partie proximale dans la partie distale déployée.
