Abstract
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.A flow restrictor device in cerebral aneurysms and positioner-releasing assembly thereof, wherein the device comprises a body of radially expandable sheet material, consisting of a succession of interconnected arms by means of connecting bridges between those defined cells, which are through openings through the body, said body presenting a general peripheral area of high porosity where the cells are the largest, an intermediate zone of medium porosity, surrounded by said general peripheral area of high porosity, and where the cells have an intermediate size, and a central zone of low porosity, surrounded by said intermediate zone of medium porosity, and where the cells are smaller, so that the device can be implanted in the neck of the aneurysm to restrict the influx towards it without impeding normal blood flow in the main vessel and adjacent vessels where it is installed the device. There is also a navigation system, positioning and release of the device that allow the specialist the manipulation and proper implementation of the device according to the needs of each patient.
