The introducer sheath can be loaded onto a vasoocclusive device after removal of the vasoocclusive device from a microcatheter, to permit the vasoocclusive embolic coil assembly to be used again during a clinical procedure. The sheath includes a hollow, elongated tubular member with a longitudinal slot formed in the upper wall of the elongated tubular member and extending along the length of elongated tubular member. The upper wall of the elongated tubular member adjacent to the slot has an angled configuration to accept the vasoocclusive device. The sheath may include wing members extending outwardly from the angled configuration on the outside surface of the hollow, elongated tubular member to facilitate insertion of the vasoocclusive device into the sheath. The elongated tubular member may also consist of a segment with no slot attached to a flexible pusher member to facilitate initiation of loading of the vasoocclusive device into the sheath.
On peut charger la gaine d'introduction sur un dispositif vasoocclusif après avoir retiré celui-ci d'un microcathéter pour permettre à l'assemblage vasoocclusif de spire métallique pour embolisation d'être réutilisé durant une procédure clinique. La gaine comprend un élément tubulaire creux et oblong doté d'une fente longitudinale formée dans la paroi supérieure de l'élément tubulaire oblong et qui s'étend sur la longueur de l'élément tubulaire oblong. La paroi supérieure de l'élément tubulaire oblong adjacent à la fente se caractérise par une configuration inclinée pour accepter le dispositif vasoocclusif. La gaine peut comprendre des éléments alaires qui s'étendent vers l'extérieur de la configuration inclinée sur la surface externe de l'élément tubulaire creux et oblong afin de faciliter l'insertion du dispositif vasoocclusif dans la gaine. L'élément tubulaire oblong peut également être pourvu d'un segment sans fente attaché à un élément directeur souple pour faciliter l'initiation du chargement du dispositif vasoocclusif dans la gaine.
