Title (EN) IMPROVED EMBOLIC COIL
(FR) SPIRALE AMELIOREE POUR EMBOLISATION
Abstract:
(EN) An embolic coil comprises an elongated core element formed of a shape memory material treated to define a memorized secondary coil shape and an elongated outer element wound around the elongated core element to define a primary coil shape of the embolic coil. A method of forming an embolic coil, comprises the steps of imparting a memorized shape to a core element formed of a shape memory material, wherein the memorized shape defines a secondary coil of the embolic coil and straightening the core element in combination with the steps of winding an elongated outer element around the straightened core element to form a primary coil of the embolic coil and releasing the straightened core element when the device has been positioned at a deployment location to form the secondary coil of the embolic coil.
(FR) L'invention concerne une spirale pour embolisation, qui comprend : un élément central allongé fait d'une matière à mémoire de forme ayant été traitée en vue de définir une forme mémorisée de spirale secondaire ; et un élément extérieur allongé, enroulé autour de l'élément central allongé, qui définit la forme primaire de la spirale. L'invention concerne aussi un procédé de formation de la spirale pour embolisation, qui comporte les étapes consistant à : donner une forme mémorisée à un élément central fait d'une matière à mémoire de forme, cette forme définissant une forme secondaire de la spirale ; redresser l'élément central ; enrouler un élément extérieur allongé autour de l'élément central redressé pour produire la forme primaire de la spirale ; et libérer l'élément central redressé lorsque le dispositif a été positionné dans un site de déploiement, afin de produire la forme secondaire de la spirale.
