Abstract

Una válvula cardiaca protésica caracterizada exterior periférico, generalmente anular, que tiene una superficie de pared exterior, al menos una laminilla dispuesta en dicho cuerpo, incluyendo dicha laminilla superficies de borde lateral opuestas y superficies de borde delantera y trasera, y medios de soporte de la laminilla capaces de soportar a dicha laminilla de manera que pueda realizar un movimiento en respuesta a inversiones del sentido de flujo de fluido a través de dicho cuerpo, entre una posición abierta, en la que dicha laminilla se encuentra sustancialmente paralela paso de fluido a través de dicho cuerpo, y una posición cerrada, en la que dicha laminilla se extiende en ángulo a través de dicho cuerpo, comprendiendo dichos medios de soporte de la camilla salientes laterales en superficies de bordes laterales opuestas de la laminilla se extiende en ángulo a través de dicho cuerpo, comprendiendo dichos medios de soporte de la laminilla salientes laterales en superficies de borde laterales opuestas de la laminilla y medios de cavidad de guía para cada uno de dichos salientes laterales, estando cada uno de dichos medios de cavidad de guía dispuestos en la superficie de pared inferior de dicho cuerpo, entre dichas superficies de borde delantero y dichas superficies de borde trasero de dicha laminilla, estando dispuesto cada uno de dichos medios de cavidad de guía para recibir uno de dichos salientes laterales con el fin de guiar en un movimiento (le pivotamiento y de traslación limitado a cada una de dichas laminillas entre dichas posiciones abierta y cerrada, en respuesta a inversiones en la dirección del paso de fluido a través de dicho cuerpo.
