Title
(EN) VASCULAR REMODELING DEVICE
(FR) DISPOSITIF DE REMODELAGE VASCULAIRE
Abstract
(EN)
Described herein are flexible implantable devices or stents that can conform to the shape of vessels of the neurovasculature. In some embodiments, the devices can direct blood flow within a vessel away from an aneurysm or limit blood flow to the aneurysm. In some embodiments, a vascular remodeling device includes a first section and a protruding section. During deployment, the device expands from a compressed configuration to an expanded configuration. The first section anchors the device in an afferent vessel and/or in an efferent vessel of a bifurcation and the protruding section is positioned in the junction of the bifurcation having an aneurysm and across the neck of the aneurysm or at least partially within the aneurysm.

La présente invention concerne des dispositifs implantables flexibles ou des endoprothèses qui peuvent s'adapter à la forme de vaisseaux de la neurovascularisation. Dans certains modes de réalisation, les dispositifs peuvent diriger la circulation sanguine dans un vaisseau dans la direction opposée à un anévrisme ou limiter la circulation sanguine vers l'anévrisme. Dans certains modes de réalisation, un dispositif de remodelage vasculaire comprend une première section et une section saillante. Pendant le déploiement, le dispositif s'étend depuis une configuration rétractée vers une configuration déployée. La première section ancre le dispositif dans un vaisseau afférent et/ou dans un vaisseau efférent d'une bifurcation et la section saillante est positionnée dans la jonction de la bifurcation ayant un anévrisme et de part et d'autre du col de l'anévrisme ou au moins partiellement dans l'anévrisme.
