Title (EN) BIFURCATED STENT WITH TWISTED HINGES
(FR) IMBRICATION DE POINTS D'ARTICULATION DE TORSION DANS UN SYSTÈME BIFURQUÉ
Abstract:
(EN) A bifurcated stent (1) that uses turning segments (53) to reduce the strain at regions which bend at extreme angles. The turning segments can be placed on side branch petals or on connectors connecting the petals to the stent body. Combining the turning segments with connectors of different length and tethers provides for a stent with high flexibility that can accommodate various shaped body vessels. This design allows the bifurcation branch to extend easily, to a useful distance, and to be deployed along oblique angles. Moreover, this design avoids the problems of angularly strained side branch.
(FR) L'invention concerne un système bifurqué faisant intervenir des éléments incurvés pour réduire les déformations se produisant dans des zones incurvées à des angles extrêmes. Les éléments incurvés peuvent être placés sur des pétales de branches latérales ou sur des connecteurs reliant les pétales au corps de stent. La combinaison des éléments incurvés et des connecteurs qui présentent des longueurs différentes et des fils de fixation différents permet d'obtenir un stent présentant une grande flexibilité et pouvant s'adapter à des vaisseaux corporels de formes variées. Cette conception permet à la branche de bifurcation de se prolonger facilement, à une distance utile, et d'être déployée le long d'angles obliques. En particulier, l'avantage de l'invention est qu'elle permet d'éviter les problèmes de branches latérales angulairement déformées.
