Title (EN) ACTIVE INTRODUCER SHEATH SYSTEM
(FR) SYSTÈME ACTIF DE GAINE DE DISPOSITIF D'INTRODUCTION
Abstract:
(EN) The active introducer sheath systems disclosed herein are expanded by activating a translation mechanism at the handle. The sheath has an inner cylindrical structure of comingled fixed and mobile elongate rods bound together by an attachment line. Activating the translation mechanism causes the mobile rods to move axially with respect to the fixed rods, changing the internal tension in the attachment line. Increased tension draws the fixed and mobile rods closer together, decreasing the diameter of the cylindrical structure. Decreased tension in the attachment line enables the fixed and mobile rods to move apart, increasing the diameter of the cylindrical structure. A prosthetic device, such as a prosthetic heart valve, can be routed through the expanded sheath and to the implantation site. During implantation, the sheath can be contracted back to its original outer diameter, and expanded again for retrieval of the delivery apparatus.
(FR) L'invention concerne des systèmes actifs de gaine de dispositif d'introduction qui sont étendus par activation d'un mécanisme de translation au niveau de la poignée. La gaine a une structure cylindrique interne de tiges allongées fixes et mobiles combinées liées ensemble par une ligne de fixation. L'activation du mécanisme de translation amène les tiges mobiles à se déplacer axialement par rapport aux tiges fixes, modifiant la tension interne dans la ligne de fixation. Une tension accrue tire les tiges fixes et mobiles pour les rapprocher les unes des autres afin de réduire le diamètre de la structure cylindrique. Une tension réduite dans la ligne de fixation permet aux tiges fixes et mobiles de s'écarter afin d'augmenter le diamètre de la structure cylindrique. Un dispositif prothétique, tel qu'une valvule cardiaque prothétique, peut être acheminé à travers la gaine étendue et vers le site d'implantation. Pendant l'implantation, la gaine peut être ramenée par contraction à son diamètre externe d'origine et étendue à nouveau pour la récupération de l'appareil de pose.
