Title (DE) STENT-GRAFT-SYSTEM UND EIN VERFAHREN ZUR KOPPELUNG VON STENT-GRAFT ALS STENT-GRAFT-SYSTEM
(EN) STENT GRAFT SYSTEM AND A METHOD FOR COUPLING STENT GRAFTS AS A STENT GRAFT SYSTEM
(FR) SYSTÈME STENT-GREFFON ET PROCÉDÉ DE COUPLAGE D'UN STENT-GREFFON COMME SYSTÈME STENT-GREFFON
Abstract:
(DE) Die Erfindung betrifft ein Stent-Graft-System (1) mit einem auf einen Durchmesser bezogenen expandierbaren ersten Stent-Graft (2) und mindestens einem zweiten Stent-Graft (3), wobei der erste Stent-Graft (2) zumindest Bereichsweise, eine schlauchförmige Netzstruktur (4) aufweist, die in einem expandierten Modus eine Netzstruktur (4) mit im Wesentlichen kreisrunden, ringförmigen Maschen (5) aufweist, wobei der mindestens zweite Stent-Graft (3) an einem distalen Ende (6) nach außen stehende Widerhaken (7) aufweist, über die der mindestens zweite Stent-Graft (3) an den ersten Stent-Graft (2) im expandierten Modus ankoppelbar ist, wobei der mindestens zweite Stent-Graft (3) mit dem distalen Ende (6) eine mit seinem Durchmesser korrespondierende kreisrunde, ringförmige Masche (5) durchstößt und mit den jeweiligen nach außen stehenden Wderhaken (7) an der kreisrunden, ringförmigen Masche (5) eingreift. Ferner betrifft die Erfindung Verfahren zur Koppelung von Stent-Grafts als Stent-Graft-System.
(EN) The invention relates to a stent graft system (1) with a first stent graft (2) expandable in respect of a diameter, and with at least a second stent graft (3), wherein the first stent graft (2) at least in some areas has a tubular net structure (4) which, in an expanded mode, has a net structure (4) with substantially round annular meshes (5), wherein the at least second stent graft (3) has, at a distal end (6), outwardly extending barbs (7) via which the at least second stent graft (3) can be coupled to the first stent graft (2) in the expanded mode, wherein the distal end (6) of the at least second stent graft (3) passes through a round annular mesh (5) of corresponding diameter and, with its outwardly extending barbs (7), engages on the round annular mesh (5). The invention further relates to a method for coupling stent grafts as a stent graft system.
(FR) L'invention concerne un système stent-greffon (1) comprenant un premier stent-greffon (2) expansible par rapport à un diamètre et au moins un deuxième stent-greffon (3), le premier stent-greffon (2) présentant au moins par endroits une structure en filet tubulaire (4) ayant des mailles (5) annulaires, sensiblement circulaires, le ou les deuxièmes stents-greffons (3) présentant sur une extrémité distale (6) des ergots (7) dépassant vers l'extérieur, par le biais desquels le ou les deuxièmes stents-greffons (3) peuvent être couplés au premier stent-greffon (2) en mode expansé. Le ou les deuxièmes stents-greffons (3) transpercent avec l'extrémité distale (6) une maille (5) annulaire, circulaire correspondant à son diamètre et viennent en prise avec les ergots (7) respectifs, dépassant vers l'extérieur, contre la maille (5) annulaire circulaire. L'invention concerne en outre des procédés pour le couplage de stent-greffon comme système de stent-greffon.
