Abstract:
(DE) Die Erfindung betrifft einen Stent (1) mit einem tubulären Stützgerüst (2) aus axial aufeinanderfolgenden untereinander verbundenen Ringsegmenten (3-16). Erfindungsgemäss sind zumindest zwei benachbarte Ringsegmente (6) und (7) bzw. (12 und 13) durch formschlüssig ineinander greifende Koppelelemente (20, 21) verbunden, welche als zueinander komplementäre Klauenverbinder (31, 32) ausgestaltet sind. Die Koppelelemente (20, 21) stehen in Stentlängsachse L axial gegenüber den Ringsegmenten (6 und 7); (12 und 13) vor. Ferner können Ringsegmente (3-6; 7-12; 13-16) durch feste Verbinderstreben (22) untereinander zu Stentabschnitten (23, 24, 25) zusammengeschlossen sein.
(EN) The invention relates to a stent (1) comprising a tubular supporting frame (2) that consists of axially successive interconnected ring segments (3-16). According to the invention, at least two neighboring ring segments (6 and 7 or 12 and 13) are connected by means of coupling elements that positively engage with each other and are embodied as complementary clamping connectors (31, 32). The coupling elements (20, 21) axially protrude from the ring segments (6 and 7; 12 and 13) along the longitudinal axis (L) of the stent. In addition, ring segments (3-6; 7-12; 13-16) can be interlocked by means of fixed connector struts (22) so as to form stent sections (23, 24, 25).
(FR) L'invention concerne un stent (1) comprenant une armature tubulaire (2) constituée de segments annulaires (3-16) se succédant dans le sens axial et reliés entre eux. Selon l'invention, au moins deux segments annulaires voisins (6 et 7 ou 12 et 13) sont reliés par des éléments d'accouplement (20, 21) s'emboîtant par liaison de forme, ces éléments se présentant sous la forme de griffes de liaison complémentaires (31, 32). Lesdits éléments d'accouplement (20, 21) font saillie axialement par rapport aux segments annulaires (6 et 7 ; 12 et 13) dans le sens longitudinal (L) du stent. Par ailleurs, des segments annulaires (3-6 ; 7-12 ; 13-16) peuvent être assemblés par l'intermédiaire d'entretoises de liaison fixes (22) de façon à former des sections de stent (23, 24, 25).
