Title (EN) EXPANDABLE SHEATH WITH LONGITUDINALLY EXTENDING REINFORCING MEMBERS
(FR) GAINE EXTENSIBLE DOTÉE D'ÉLÉMENTS DE RENFORCEMENT S'ÉTENDANT LONGITUDINALEMENT
Abstract:
(EN) An expandable delivery sheath includes an elastic outer tubular layer and an inner tubular layer. The inner tubular layer include a thick wall portion integrally connected to a thin wall portion. The thin wall portion can include longitudinal reinforcing members/rods that facilitate unfolding during the passage of the implant, thus decreasing the push force and increasing the consistency of the push force. The inner tubular layer can have a non-expanded or folded condition wherein the thin wall portion folds onto an outer surface of the thick wall portion under urging of the elastic outer tubular layer. When an implant passes therethrough, the outer tubular layer stretches and the inner tubular layer unfolds into an expanded lumen diameter. Once the implant passes, the outer tubular layer again urges the inner tubular layer into the non-expanded condition with the sheath reassuming its smaller profile.
(FR) L'invention concerne une gaine de distribution extensible qui comprend une couche tubulaire externe élastique et une couche tubulaire interne. La couche tubulaire interne comprend une partie de paroi épaisse reliée d'un seul tenant à une partie de paroi mince. La partie de paroi mince peut comprendre des éléments/tiges de renforcement longitudinaux qui facilitent le dépliage lors du passage de l'implant, réduisant ainsi la force de poussée et augmentant la cohérence de la force de poussée. La couche tubulaire interne peut présenter un état comprimé ou plié dans lequel la partie de paroi mince se plie sur une surface externe de la partie de paroi épaisse sous la poussée de la couche tubulaire externe élastique. Lorsqu'un implant passe à travers celle-ci, la couche tubulaire externe s'étire et la couche tubulaire interne se déplie dans un diamètre de lumière expansé. Une fois que l'implant passe, la couche tubulaire externe pousse à nouveau la couche tubulaire interne dans l'état comprimé, la gaine retrouvant alors son profil le plus petit.
