Title (EN) DEVICE FOR RESTRICTING FLOW IN BRAIN ANEURYSMS AND ASSEMBLY FOR POSITIONING AND RELEASING THE DEVICE
(ES) DISPOSITIVO RESTRICTOR DE FLUJO EN ANEURISMAS CEREBRALES Y CONJUNTO POSICIONADOR-LIBERADOR DEL DISPOSITIVO
(FR) DISPOSITIFS LIMITEURS DE FLUX DANS LES ANÉVRISMES CÉRÉBRAUX ET ENSEMBLE DE POSITIONNEMENT/LIBÉRATION DU DISPOSITIF
Abstract:
(EN) The invention relates to a device for restricting flow in brain aneurysms and to an assembly for positioning and releasing same, wherein the device comprises a body made from a radially expandable, laminar material and consisting of a succession of arms connected together by means of joining bridges between which cells are defined, the cells being openings that pass through the body. The body comprises: a general peripheral high-porosity zone having the largest cells; an intermediate medium-porosity zone surrounded by the general peripheral high-porosity zone and having intermediate-sized cells; and a central low-porosity zone surrounded by the intermediate medium-porosity zone and having the smallest cells, such that the device can be implanted in the neck of the aneurysm to restrict the inflow towards same, without blocking the normal blood flow in the main vessel and adjacent vessels where the devices installed. According to the invention, a system for navigating, positioning and releasing the device is also provided, allowing the specialist to manipulate the device and appropriately implant same according to the requirements of each patient.
(ES) 1. Un dispositivo restrictor de flujo en aneurismas cerebrales y conjunto posicionador-liberador del mismo, en donde el dispositivo comprende un cuerpo de material laminar expandible radialmente, que consiste en una sucesión de brazos interconectados entre sí por medio de puentes de unión entre los que se definen celdas, que son aberturas pasantes a través del cuerpo, presentando dicho cuerpo una zona general periférica de alta porosidad donde las celdas son las de mayor tamaño, una zona intermedia de mediana porosidad, rodeada por dicha zona general periférica de alta porosidad, y en donde las celdas tienen un tamaño intermedio, y una zona central de baja porosidad, rodeada por dicha zona intermedia de mediana porosidad, y en donde las celdas tienen el tamaño menor, de manera que el dispositivo puede implantarse en el cuello del aneurisma para restringir el influjo hacia el mismo sin obstaculizar el flujo sanguíneo normal en el vaso principal y vasos adyacentes donde se instala el dispositivo. Hay además un sistema de navegación, posicionamiento y liberación del dispositivo que le permiten al especialista la manipulación y adecuada implantación del mismo según las necesidades de cada paciente.
(FR) 1. Dispositif limiteur de flux dans les anévrisme cérébraux et ensemble de positionnement/libération dudit dispositif. Le dispositif comprend un corps formé d’un matériau plan, extensible radialement, constitué d’une succession de bras reliés entre eux par des ponts de liaison, entre lesquels sont formées des cellules qui sont des ouvertures traversantes du corps, ledit corps présentant une zone principale périphérique à porosité élevée, qui comporte les cellules les plus grandes, une zone intermédiaire à porosité moyenne, entourée par ladite zone périphérique principale à porosité élevée qui comporte des cellules de taille intermédiaire, et une zone centrale à faible porosité qui comporte les cellules les plus petites, de telle manière que le dispositif peut être implanté sur le collet de l’anévrisme pour limiter le flux sanguin entrant dans ce dernier sans obstruer le flux sanguin normal dans le vaisseau principal et les vaisseaux adjacents au niveau desquels le dispositif est installé. Un système de navigation, de positionnement et de libération du dispositif permet la manipulation et l’implantation adéquate du dispositif par le spécialiste, conformément aux besoins de chaque patient.
