Abstract

Una prótesis de válvula cardiaca que comprende un cuerpo de válvula anular que tiene una pared interior formando un camino de paso central a través de ella generalmente de sección transversal circular, un par de hojas dimensionadas para bloquear el flujo de sangre a través delimitado camino de paso cuando las referidas hojas están dispuestas en una posición cerrada, teniendo cada una de las citadas hojas un borde mayor arqueado que hace tope en el referido cuerpo de la válvula en la posición cerrada y borde menor practicamente plano, y medios que acoplan con posibilidad de pivotar cada una de las citadas hojas y el referido cuerpo de la válvula para un movimiento de rotación relativo entre las posiciones abierta y cerrada, cuyos medios de acoplamiento incluyen pares de depresiones formadas en posiciones generalmente opuestas en la citada pared interior y pares de guías que se extienden lateralmente desde cada una de las citadas hojas, teniendo cada una de las depresiones citadas una secciónsuperior o de aguas arriba que está alineada prácticamente paralela al eje del referido camino de paso central y una sección inferior o de aguas abajo que forma un ángulo hacia fuera desde el punto de unión.
