Abstract

UNA VALVULA DE CORAZON PRTTESICA (VALVULA) COMPUESTA DE UN ANILLO BASE (1) ADAPTADO PARA ALOJAR UN ANILLO DE SUTURA EN SU EXTERIOR Y DOS FILIOLOS (8,9) DISPUESTOS PARA ASUMIR UNA POSICION ABIERTA Y UNA POSCION CERRADA EN ORDEN PARA REGULAR EL FLUJO SANGUINEO EN UNA DIRECCION, EN DONDE, EL ANILLO BASE (1) ES PROVISTO CON DOS CAVIDADES (5) CON SUPERFICIES CURVADAS SITUADAS EN PROSICIONES OPUESTAS DIAMETRALMENTE. CADA UNO DE LOS HUECOS COMUNICA CON EL EXTERIOR A TRAVES DE UNA ABERTURA COMO CHIMINEA (7'') FORMADA EN EL CUERPO DEL ANILLO BASE (1) EN CORRESPONDENCIA CON LOS HUECOS PLANA (14) QUE LIMITA CON SU PARTE SUPERIOR Y MAS BAJA, SEPARADAS POR UN CUERPO SEPARADOR (6) ESENCIALMENTE EN LA FORMA DE UNA GUIA SEMIESFERICA.
